Jamie's Boosted Hyundai Elantra (Oct '11)

This is an old video that I've decided to post practically un-edited. A few parts were skipped regarding off-topic babble in order to keep it under 10 minutes. You've seen this car in another video. There really is no way to determine how many different cars contributed to this build. Every last part on it (except the one featured in this video) was previously used on another vehicle. Absolutely nothing came new in a box. The owner put enough 4g63's together in a lifetime to have extra gaskets and seals laying around to exclusively use junkyard parts to build a whole car. In the last video, you saw me contribute all the turbo parts to this build. Used 150,000 mile old stock DSM turbo parts including a worked 14b. I'm happy to show it to you all put together. Check the other video of this car if you want more details on the engine build. None of the internals have changed.

Cylinder Head 204 - Porting & Polishing
This is a first-generation 1992 1.6L Hyundai Elantra small-combustion-chamber head. Thats what it is. It's a J1 engine's cylinder head. In Cylinder Head 106 I talked about the mainstream porting theories as they are discussed. We looked at a cylinder head that I have thousands of dollars of professional work performed on, and a bone-stock second-generation head that I didn't port. In this video I just might do something you haven't seen done before. For some, that may be uncomfortable. The port and polish job I perform here is what I think will work best for my current build. This is not an extreme killer port job. What will be different here is where port textures are concerned, I will be following the advice of a reputable source that will remain un-named. You're free to port yours differently than I do in this video, and I give you that out, around the 20 minute marker. The Hyundai is far from being an ultimate-performance build. It's a $400 box of scraps with nothing but time invested. It's perfect for this video. My finished product WILL be an improvement over what I had. I don't yet have access to a flow bench. I still have an achievement to un-lock. As far as you should be concerned with the techniques I employ... without flow numbers there is no evidence of what this will do, but we will gather lots of info from dynp sessions and drag strip time slips. If I could test it on a flow bench, I would. There are MANY, and when I say many, I mean thousands of flame war mongering pirates floating around on rough seas with a hair trigger cannon finger itching to fire if you port a head any differently than what the herd mentality says to do while porting a cylinder head. I cover the herd mentality because it has merit. It's been tested. Tried and true. But I don't follow it to the letter of the law. I'm definitely not here to de-bunk it. I would port a cylinder head differently for each build based on how that engine was used. There's an extremely valid reason why relating to air speed. It's not the texture of a port that maximizes the effect of fuel atomization, but the velocity of the air running through an x or y sized valve. The driving factor in this is the piston speed. I'm not going to give you the technical information, but will refer you to information about the Lovell factor. There's a better description of this in the links below, and even a calculator to help you find your engine's sweet spot. Why the Lovell factor is important: https://www.highpowermedia.com/blog/3346/the-effect-of-valve-size Lovell gas factor calculator: http://www.rbracing-rsr.com/lovellgascalc.html Only people who have flow testing equipment know for sure what really works and have the capability to produce a perfectly-matched port job for the ultimate performance build. Those guys know the definition of ultimate, and THEY are floating below the water Aegis-class submarines ready to blow your comment up if you don't know what you're talking about. They don't care if you're an armchair mechanic or a herd of pirates. I will say, they're zoomed in pretty close on me right now, and I'm expecting to take a few hits. My work will be tested based on Dyno and drag strip performance, and the results will be posted here. Fortunately, those kinds of videos are a WHOLE LOT EASIER TO MAKE!!!





Cylinder Head 205 - Degree 4g63 Camshafts
This video is all about establishing your valve timing baseline, and adjusting your camshafts to the manufacturer's spec. It's only ONE of several steps that should be performed when you're assembling your engine on an engine stand. Establishing these conditions with accuracy while your engine installed in the car is a near-impossibility, and the reason why... is demonstrated in this video. There are several challenges to overcome when performing these procedures on a 4gxx series Mitsubishi engine, and they're all defeated here. The cylinder head used in this video is a J1 spec '92 Hyundai Elantra small-combustion chamber head which has had several valve jobs and has been resurfaced multiple times by budget engine remanufacturers who didn't care about quality control, as well as performance shops who do. It has had no less than .040" removed from the head gasket surface, the valves are recessed because of all the valve jobs performed, and at some point when it was cut, it wasn't level. Removing material from the deck surface will change the installed camshaft centerline, and that will change your engine's valve timing events even if all other parts remain the same. I would claim this is a multi-part video except that I've got the videos broken up by topic already, and this one is all about setting your cams to the manufacturer's specification. It is not the end of testing that will be performed with these tools. The basics concerning the process and tool fabrication are covered here. Further discussion on this topic concerning the effects of advancing or retarding camshafts from spec, and for checking your valve clearance will be in the videos that follow. I had to end this video after the manufacturer's spec was achieved to make it easier to digest, and because it would have created a video greater than one hour in length despite the break-neck speeds that things happen here on Jafromobile. Where your cams are set determine how the swept volume of the combustion chamber gets used. The information on the manufacturer's spec sheet is their recommendation for baseline settings that will help you get the most out of those camshafts. Whether or not your engine can operate with those specifications without additional hardware or without causing a catastrophic failure will be expanded upon in Cylinder Head 206. The next video should be used as a companion to this video because establishing the manufacturer's baseline is not the end of the assembly or testing process. It's only half the battle. Should you be lucky enough to find your combination of parts allow your camshafts to fit and requires no additional adjustment after assembly, the steps in this video and in Cylinder Head 206 should still be performed if you are doing the assembly yourself. Failure to inspect these variables may lead to a tuning nightmare once the engine is back in the car, hard starts, or worse... bent valves and damaged wrist pins. Making these tools and performing these steps will give you the peace of mind to know with certainty that your engine is operating safely at its peak performance.





Hyundai 4g63 Assembly Part 3
I have bad news. The big camera's playback heads bit the dust from extensive prolonged use. I wore out the tape drive. No manner of cleaning tapes can fix what it's been through. I've talked many times about how much footage goes into one of my 15 to 30 minute videos, and for every hour of video footage I've shot, the camera does double-duty because after shooting, it has to be played back in real time during capture. I've done more than 130 videos this way, probably over 2000 hours of use in the harshest of environments, and it just couldn't handle it any longer. I shot several more tapes beyond what's in this video that I can't even import because the play heads failed. I don't know if any of that video even stuck to the tapes? The lost footage from the last video was an early and un-recognized sign of what was soon to come. I know I joked about it, but in reality it's really not very funny at all. I can't afford a backup for a piece of equipment like this, so it's something I don't have. As bad as this news might feel to you, I feel it 21,000 times over and I mean that. This couldn't come at a worse time and expense for me, and at a point where my production was really starting to wrap up on this project to move on to bigger and better things. It's the only camera I have that can do what I do here on this channel, so I'm forced to stop production for now. Even though my camera is huge, 7 year old HDV technology, these things still sell for several thousand dollars used because they record un-compressed video unlike every other flash storage based solution available at twice the price. 3CCD 1080/60i HD cameras that shoot to tape have advantages that you can't affordably achieve with solid-state media. I have to use un-compressed footage to do what I do here or else there's nothing left of the video quality after 7 exports and a final mpeg compression. The Sony Action Cam can't do it, we learned that in a previous test video. Even if it could, it can't do close-ups and everything's fisheyed. Buying a low-end 4K camera is impractical because I can't efficiently or effectively edit that video without a $9,000 computer. Jafromobile is just not that big of a channel, and I do this completely un-sponsored and at my own expense with the help of a handful of friends who volunteer their talent, time and information. It's the epitome of low-budget and what it earns still doesn't come close covering the channel's equipment and expenses as they occur. People have urged that I do a kickstarter, but I can't bring myself to ask for that from the community. I don't sell a product or offer services so there is no profit margin. I can't accept money for something that happens only at the speed of my available resources. To me, this channel is my proverbial gift horse to all of you. http://en.wiktionary.org/wiki/don't_look_a_gift_horse_in_the_mouth I know what you're thinking and I realize this is a grim conclusion to this video. It sounds like I'm down for the count, but don't rush to the down vote button just yet. As of the upload date of this video, I'm paying out of pocket to fix a ridiculously expensive 3CCD 1080HD broadcast quality video camera so that these projects can resume, and so that I can bring the final assembly steps to you in the same quality you've grown used to seeing here on Jafromobile. If I wear out a camera every 3 years, then so be it. This is love, and no expense is too great. The big camera is being fixed by its manufacturer, and I'm expecting the repair to cost as much as replacing it. I sincerely hope that's not the case. Hopefully my production only has to take a short break. Once production resumes and I can import these tapes, I've got some really awesome stuff coming up and I hope every last one of you is here to see it. I may have a few other backlogged nuggets I can upload, and as always I'm happy to discuss this in the comments and provide updates on the repair as I get them. Update: Awaiting quote due by 5/16 according to the repair agreement. 5/9/2014 9:17:00 AM DELIVERED NEWPORT NEWS, VA US 5/9/2014 5:36:00 AM DESTINATION SCAN NEWPORT NEWS, VA US 5/9/2014 12:04:00 AM ARRIVAL SCAN NEWPORT NEWS, VA US 5/12/2014 - Repair paid in full $440. Far less than I was expecting. I'm glad they still make parts for 7 year old professional equipment. Thank You Canon, USA! Repair should be complete within 7 business days from receipt of payment. The quote only took them 24 hours and they quoted a week just for the estimate, so at this rate I should be back up and running once again very soon. Thank ALL of you for your kind words, HUGE generosity, and all of the moral support. I swear I have the best subscribers on YouTube!





New Year's Eve Hyundai Teardown
It goes like this. One of the best friends I've ever had built this car from junk parts. He said it best, "it was built from literally a box of scraps". It ran an 13.2 in the quarter mile using no aftermarket performance parts of any kind. That quarter mile time was limited by traction. I know this car had more in it, but I never managed to get it to stick before encountering this. More on this build... The proper bolts were not always available, but the builder knows isht from Shinola. Even though this engine defies all engineering logic from Mitsubishi, the builder knew what would work and what would not. Budget was of the most primary of his concerns, and it shows at every turn, and it's what brought us to the kind of failure we find in this video. I asked him what bearings he used. He said, "...the least expensive ones I could find. Picture Aluglides. Now picture generic Aluglides. I paid half-as-much for those bearings as I would for generic Aluglides. Bolt too long? Put a nut on it and shorten it. Oil pan too close to the pickup? Hammer a big dent in it to make clearance for it. Wrong water pipe? Put a brass hardware store tee in the line to tap a turbo coolant feed. Forget buying ARP's, this is an all-standard re-used factory fastenere'd no-oil-squirter .030"-overbore 6-bolt with the cut-off balance shaft mod. It's using a small combustion chamber head off of a 1.6L Mirage with a 2.0L non-turbo block. The plug wires are used. The radiator hoses were used. Everything but the head gasket came from a junk car. The FWD turbo gearbox is from my 150,000 mile old Plymouth Laser that donated the block to the Colt. This is one of the most amusing cars I've ever wrapped my fingers around because of these kinds of character-building attributes. Nevermind that the chassis has less than 70,000 miles on it (not bad for a '92), it's just that it's built without using any new parts. Parts were substituted when they were not available, and it's ridiculously powerful. Thank you Jamie. You discovered your answer. I'm happy to help. I'll be changing some things like the oil pan bolts, bearing quality, some of the plumbing and fixing a few wiring harness problems, but I'm not changing anything else if I can avoid it. This car was never intended to have anything upgraded to deliver raw power, and I'll do my best to keep it that way, replacing and restoring what failed so that we can keep pushing these generic non-turbo .030" over pistons to the limit. Apparently, 24 PSI from a 14b is not enough. In the meantime, my diagnosis is that excessive oil pressure lead to the breakdown of the #1 bearing. After all, it's the 1st bearing in-line in the oil system on the main gallery. It's the most isolated from clutch harmonics, yet it was the one that spun. The #1 bearing supplies the oil pump. The teardrop on the head is nearly gone from head resurfacing, and this is a no-balance-shaft no-oil-squirter block. I think high oil pressure is why it falls on its face above 6000 rpms. There's a restriction upstream from the lifters and they deflate at high RPMs, losing lift. I'll fix it. I've got the parts.





Jamie's 92 Hyundai Elantra with bastard 4g63 swap
There's a history both behind this car, and the friendship with this person. I met him 10 years ago following a random conversation that I injected myself into between 2 strangers at an auto parts store. I had just bought a '92 Civic CX with crap compression and was picking up some service parts to keep it limping and useful while I built my DSM. I overheard him mention "4g63" to somebody as I walked by, so I turned around and introduced myself without any clue that he was one of the "realest" people I've ever known. What occurred for me in the following discussion was an awakening on my part. He led me to an adjacent parking lot where an un-assuming Hyundai Elantra sat. This isn't the one, but is one of many factory cars that he's swapped a 4g63 into. What he managed to get through my big thick skull was there were lots of great inconspicuous chassis that you can simply bolt a 4g63 into. Over time it became evident where you can find lots of "racing" parts, from factory equipment on various mini-vans, station wagons, much of the Hyundai line-up from '92-'95. During the "DSM Years", there were plenty of cars from other manufacturers that made dynamite donors, and this sparked my ability to be frugal in some of my ventures. If you ever meet Jamie, expect his knowledge of car parts both inside and outside the realm of Mitsubishi to be as unassuming on the surface as the car in this video. He has true talent. Finds peace and happiness in a junkyard full of decay, and skills that create useful high-performance art from what many consider rubbish. Because he's already taken time walking around with parts from one car and bolting them on to others to see if they'll fit, worked as a machinist's apprentice rebuilding everything under the sun, and done the tech work to analyze failures in all of it, he's often my go-to guy for advice when things aren't working correctly. Many times he's come through for me in a pinch and shed light on something I didn't understand. That goes both for examples in the automotive domain, and in real life when I've hit hard times. Many of my parts for the Colt came from his past builds on various Mitsubishis and Hyundais. In fact... many of my Colt parts have come from this very car. He gave this chassis to somebody, and they returned it later because life didn't let them finish it. I don't think it took even a month once he put his mind to working on it to get it in this state, and it was motorless-and-in-pieces. I can't wait to see these parts get bolted on this car. I think we'll have a new textbook definition of sleeper when he's done.





Major Huge Announcement
This video is a quick update on the projects here on Jafromobile right now, as well as a tour and history lesson on my latest addition. I'm always hard at work to bring you all new material based on Mitsubishi production and partnerships from 1987-1999. Also covered are what's necessary to resurrect a car that's been sitting for many years. If it's got a 4g63, to me... it's always worth saving. My channel now has 4 Mitsubishi-powered projects in the works which should be capable of delivering tons of new material. I'd like to welcome all of you from the forums. My history with Mitsubishi began in 1997, and hasn't taken a day off since. Owning one of these has been long overdue for me, and you guys have been a wealth of knowledge that helped me along my travels. An asset to the DSM community, even though this isn't a DSM.





Calculate Your Compression Ratio
This is everything you need to do to calculate your compression ratio. No foolin'. Every equation and process demonstrated. Find all your variables. Know your exact compression ratio in every cylinder. This is how you do it. Just because your service manual says your car is 7.8:1 or 8.5:1 compression doesn't mean that it is. Whenever there are casting irregularities, variations in piston height, parts that have been machined, non-OE parts, or changes to your head gasket selection, your compression ratio WILL change. It's highly probable that you're only CLOSE to spec if you've never touched your engine at all since it was "born", and that it doesn't MATCH spec. Even if it did, how would you know? This. 5 variables. V1 Swept Volume V2 Deck Volume V3 Piston-to-deck clearance V4 Piston dish cc's V5 Head combustion chamber cc's The ratio math: V1+V2+V3+V4+V5 = volume of combustion chamber at BDC V2+V3+V4+V5 = volume of combustion chamber at TDC The ratio is... (V1+V2+V3+V4+V5) ÷ (V2+V3+V4+V5) : (V2+V3+V4+V5) ÷ (V2+V3+V4+V5) or BDC ÷ TDC : TDC ÷ TDC First you fill in the variables, then you calculate volumes, then you add the volumes, then you reduce the ratio (fraction). It's that easy. Here are your magic numbers: 0.7854 = Pi quartered to the ten thousandth 16.387 = number of cc's in a cubic inch. If you divide any number in cc's by 16.387 it gives you inches. If you multiply any number in cubic inches by 16.387 it gives you cc's. Quartering pi lets you use the calculation: BORE x BORE x STROKE x .7854 = volume of a cylinder instead of... π x (BORE ÷ 2) x (BORE ÷ 2) x STROKE = volume of a cylinder Either way is right. You get the same result if you calculate pi to the ten thousandth. While I apologize for all the math, no I don't. I'm really not sorry. You actually clicked here for it whether you realize it or not. This is ALL the math, the tests, and the whole process to calculate your cylinder volumes and compression individually even if you don't know any of your variables yet. All of my numbers are present for those who want to calculate out the last 3 cylinders out of curiosity just to see how it affects cylinder volumes and compression ratios from one cylinder to the next. Why would I do that for you? Why would I deprive you of that practice? Just assume that all 4 of my combustion chambers are 41.75 ml if you do this. Clicking like share and subscribe helps a channel grow. It also motivates me. Don't sweat the camera. It's enough to know that so many of you care about what I'm doing here. From the bottom of my atmospheric dump, I thank you all! This gift horse's teeth are all over the place, but he sometimes poops gold nuggets. PS: Use ATF for your piston dish volume tests, not alcohol. Of course it's better just to use the spec sheet included with your pistons... but not everyone gets that luxury. Water is just fine for head combustion chamber tests. Dry and re-oil all parts that water touches.





CRANKWALKED? 7-bolt teardown 1080HD
Now this is a story all about how My bearings got flipped-turned upside down And I'd like to take a minute just sit right there And tell you how I used to mix and burn my gas and my air. In RVA suburbs born and raised On the dragstrip is where I spent most of my days Chillin out, maxin, relaxing all cool, 'n all shooting some BS outside with my tools When a couple of guys who were up to no good Started running races in my neighborhood I heard one little knock and my rods got scared And said "You put it in the garage until you figure out where..." I Begged and pleaded that it not be that way, But it didn't want to start and run another day. I kissed it goodbye, because the motor punched its ticket I got out my camera, said "I might as well kick it." Crankwalk yo this is bad Drinking metal shavings from an oil pan. Is this what the rumor of crankwalk is like? Hmm this won't be alright But wait I heard knocking, grinding and all that Is this the type of failure that should happen to this cool cat? I don't think so, I'll see when I get there I hope they're prepared for this video I share. Well I pulled all the bolts and when I came out There were chunks in my fluids in the pan and they drained out I aint all depressed cause I seen this before. I got my books and my wrench and we'll do it once more. I sprang into action like lightning disassembled I whistled while I worked and my hands never trembled If anything you could say that this bling is rare, and when I saw what broke I stained my underwear. I turned off the air compressor 'bout 7 or 8 And I yelled to crankcase "Yo holmes, smell ya later" I looked at my internals they were finally there To sit on my workbench and stink up the air. Audio track by RojoDelChocolate. Here's the 48,000 mile-old 7-bolt I blew up summer 2011 after over 150 drag passes, a half dozen Dyno sessions, 4 transmissions, 3 clutches and 10 years of hard all-weather use.





Jafromobile Update
LOOK! The update is actually typed here in the description. The gear-head in me never stops. I took a vacation. It still doesn't stop when I do that, either. It's just who I am. I owe you all an update. This has been the longest break in uploading I've ever taken. I've never posted anything personal like this before. I probably won't leave this up for long, but several of you have sent me messages checking on me to make sure I'm okay... and this is the easiest way to reach you all at once. The GSX build has to take a very temporary back seat. Call it a Rebecca Black... whatever you want... it's generating a stockpile I can't work around and front-seat passengers must take first-priority. My shelves are full of disassembled cars and it's become one of them. The main problem is that the middle of the garage... where the car should be... It's filled up with a yellow thing. A yellow thing that I love and want to finish. I hit a roadblock, but I bought the thing that lets me cut the thing out of the other thing so I can weld it in that thing. I've got it all figured out now... I had to take a break to figure it out. I went to California for a week. The Galant: This thing so far has cost me a lot of money since the last video, and those efforts have yet to fix the problem. I love the Galant, and it's getting a lot of my resources lately... but its problems take time and space to resolve. It's parts are practically as big as the car. I have nowhere to put them. The GSX: see... here I go again, I just can't stop thinking about it. I need a CLEAN garage to build the motor. The Hyundai: We learned that putting drag radials on a 102 mph Hyundai still nets you a 102 mph because it needs a clutch for all that extra traction. I need a garage to install a clutch. That's the update on my projects. I'm still working very hard on them to get all of them done, but I just have to finish what started on the Colt first... even though it takes time. What will follow immediately since I know other car people might enjoy the car things I saw on vacation... I look to these events for inspiration and they really get my creative chemistry flowing. I don't care how old something is, it just has more character. I don't care what brand it is, they all have their merits. Everything mechanical tells a story. The history of previous attempts to re-engineer the automobile are why we drive DSMs today. We're always re-engineering these things ourselves. It's important to see how other people do things, or else there's no way to learn from someone else's failures... and there's no way to measure your own success... see how to set your goals... Thank you for watching my videos, and I hope you can excuse me posting these events the way they occurred. They're all in vivid 1080HD as I was testing a Sony HXR-NX70U with a Merlin2 steadicam. I think many of you would be interested in seeing this material. DSM content is forthcoming, and will be uploaded very soon.





Out with the old, in with the new.
I bet you were expecting a different car. Sorry. I didn't want to, nor did I ask to troll you with this video. It's just what it is. I set out to burn some rubber, drop some bass, and have some fun in the Hyundai... and this is what happened. Testing in this video... aside from the opening scene, I shot this video at 1080p30 using an head-mounted Sony HDR-AS30V Action Cam. The camera was contained in the incuded waterproof case because I needed to test the audio with it. It sounds great with out it. It sounds only good with it. This is a test to see how I can adjust my shooting style to add 1st-person perspective to my videos for everyone's benefit. The follow-up video will be shot entirely with the "big camera" (Canon XH-A1s)





Why so SIRIUS? Kia 4g64?
This video assumes you're aware that various iterations of the 4g series Mitsubishi engines are designated as Sirius I & II. For detailed information about which engines qualify as which, visit: http://en.wikipedia.org/wiki/Mitsubishi_Sirius_engine There's also this at EvolutionM: http://forums.evolutionm.net/evo-engine-turbo-drivetrain/278462-official-hyundai-2-4l-g4js -4g64-thread.html Good luck finding info about this using Hyundai and Kia in searches. Wikipedia doesn't have any info about it grouped with the Sonatas either. There is no question what this is, well illustrated in this video. I apologize for the length of this video, but a lot of ground is covered in a short time. Hopefully there's some information in here you may someday use. I'm just trying to expose it because there doesn't seem to be any real information floating around in the forums about this yet. The car is a first-generation 1999-2005 Kia Optima sedan. It has the EVO equivalent of a 4g64 2.4L. Before using any of these parts, do your research, cross-reference your parts and know what you're getting into. Using parts from this rotating assembly in a 2g Eclipse will require aftermarket rods and/or custom pistons. This is information for those who wish to frankenstein their builds, or save a buck... whichever.... either one of those requires skill.





Jafro's Hyundai Elantra Surprise
There are some things you can't put a price on. I'm not just talking about the Hyundai. I'm talking about Jamie. I have the best friends in the world. Look what Jamie just did for all of your entertainment. He literally donated it to me to play with on this channel. This isn't just for me. Think about it. It's the only FWD DSM in my driveway, and the only one I'm likely to have. With this combination of parts, I could not have a greater challenge making this car stick. Because right now it doesn't at all. Torque steer ends at about 5700 RPMs in third gear. Boost is instantaneous. This car could never make good use of any larger of a turbo. I'm convinced with the right combo of tricks to gain timing and tweaks to make it stick, and that it will run deep into the 12's just like it is. This car is a kick in the pants to drive. A rolling burnout. Be careful with that downshift.

1g AWD Rear Subframe Bushing Replacement
These are Boostx rear subframe bushings for a 1g AWD. The factory rubber bushings can be affected by heat, cold, oils, age, air, dry rotting... they were 22 years old, and might not have been bad for a stock chassis... but this car isn't stock anymore. We're attempting to replace them in this video in order to stiffen the rear sub-frame and improve this car's launch characteristics. If the bushings are weaker than the power you're putting down vs. the weight you're moving, they can give, affecting toe, camber, caster and generally reduce the traction and handling characteristics of the car. Substituting Polyurethane bushings in place of the factory rubber bushings is a great way to solve this problem. Removing the factory bushings seems complicated if you've never done it. What it really takes is just patience and fire (and a lot of it). During this video you'll see us get impatient and grab an air chisel. That's the wrong tool for the job. It makes for cool video footage, but it simply can't do what fire does for this job. The torch you use makes a difference. The nozzle on most propane torches is a little too small to do this efficiently. The bigger nozzle the better. You'll see and hear us cover this. You can burn these bushings out with a small fire, but you'll make up for that with your time. I've received lots of great comments whenever I break out the torch. Yes, I'd love to have an Oxy-acetylene rosebud that can burn through plate steel. Yes, I'd love to have had the foresight to buy a MAP cylinder instead of propane. But the propane method for burning these out is really ideal because it's less likely to melt the steel bushing surrounds. Less of the rubber becomes airborne particulates with a colder flame. But yes, it takes longer. I think we spent a half-hour to 45 minutes torching both sets of bushings out. Once the majority of the rubber is burnt away from the sleeve, use a brass-bristled wire wheel to remove the rest. We didn't have a brass wheel big enough for the K-member bushings, so we used a steel wheel. Just keep in mind not to be too aggressive or use the wrong tools like carbide bits or grinding stones for the excess because you want to leave as much metal in there as you can. The bushings need to fit tight inside the sleeves when you're done. There are 6 washers used on the AWD subframe that have rubber castings on them to fit inside the factory rubber bushings. With the poly bushings there are no provisions for these washers the way they are. The rubber is no longer necessary, so burning that off allows you to re-use the washers rather than replace them. Be aware of which washers come from where. 2 of them have dimples in them that recess into the rear "moustache bar, boomerang bar, thing that holds the rear in". You want the big-side of that bushing against the dimpled washer, and the ring side of the bushing against the chassis where those parts meet. If you press the bushing in backwards, there's nothing to hold that spacer ring supplied with those bushings into the assembly. It will just fall off. I can't wait to hear about how these things work out because my 2g has a 100% factory suspension including the struts that came with it 160,000 miles ago. I'd like to give it the same treatment that this car received.
