How to port and polish a turbo exhaust housing

I'll fill this in later. The "book" I typed in this field before didn't save. Come back later if you want to read more about the theories behind porting and polishing.

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!!!





How to Rebuild a Turbo - Part 1 of 2
Rebuilding a td05h 16g turbo. This process can be applied to many journal bearing turbochargers. :) It definitely comes in handy to know how to do this when you are in this type of hobby. 4/25/12: Small explanation on the balancing of the rotating assembly since I get so many comments regarding it. This particular turbocharger, td05h, has its rotating assembly components balanced separately. This means each individual part (compressor wheel, turbine wheel/shaft) gets balanced separately. This allows for easy interchangeability of parts in case they need replacing. This is why I am able to install a td05 20g wheel on this turbo without having to balance the entire rotating assembly. THIS IS NOT THE CASE FOR ALL turboS OUT THERE. You need to research whether your specific turbo (if it's not td05h) was balanced as an assembly or "component balanced" like I explained above. I hope this information helps. Good luck in your projects.

Boost Leak Testing 202: Hair Spray 1080HD
Why do I know about this? I'm tired of being the one knowing all the weird crap. If everyone knows it, it won't be weird anymore. It will be commonplace. By the time I'm done sealing up all of my own Boost leaks, all of you will also be experts as well. I'm sure most of you would teach me something, too... but you subscribed, so here it comes... something I learned in my travels... Also, thanks Ilya M. I've only heard about it twice in my life. It worked great for the one time I've ever needed it, and I'm a huge fan.

Cutting Excess Guide from ProComp 210 SBC Head, custom Porting Combustion Chambers 4
Part Four of Port modificatins on ProComp 210cc aluminum SBC heads. Guide over hang from installation and correcting the combustion chambers to unshroud the spark plug is a big deal on these heads. China castings leave a lot to be desired, but still with all the work you must do it is still the bargin of the year and is a force to be reckond with when "bang per buck" is needed. The base of the spark plug should not be exposed in the chamber, and any valve guide "Overhang" will obstruck flow and create fuel "sheer" which seperates vapor to droplets that wont burn. Most Big Name companies will not take time to detial these issues as production cost prohibit these mods, so have your local machine shop take apart your heads and look for these problems before you bolt them on your prize engine. www.headbytes.com 615-212-7168

Installing a T-28 turbo on a 98 Eclipse GSX
This is an easy install. Everything is in the same location as on the factory turbo, and bolts right on. Those of you who have never installed or haven't upgraded a turbo yet might find this video more useful than those who have. Torque specs from the factory service manual are listed for what's most important. It's imperative that new turbo bolts are used with new FACTORY turbo washers. They're a specially designed spring washer, and are single-use. Use of other kinds of washers may cause bolts to break or vibrate loose. This turbo was on the car prior to this installation, but it received a port job to match the burly EVO III manifold. We installed a head-feed turbo oil feed line rather than use the factory hard lines connected to the oil filter housing. Some argue that the oil pressure from the filter housing can be harmful to the life of the turbo, but IMO, that only applies to turbos with full circumference bearing center sections. Either way, the Stainless Steel line is cool. I'll post the part number for the plug needed to block off the old line location.
