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.
More ebay 20g drag passes
Trolled by mother nature.
I thought plugging in my o2 sensor might make a difference. Scarily that's
not how things worked out. My fuel trims are all jacked up with or without
it. Airflow counts are down. I have more to do to this thing, but in an
effort to keep things real, I'm uploading what happened and what I found in
The PRIMARY reason for racing is development of both self and your
equipment. If your goal is to have an awesome street car, you can't
fully-achieve that goal without rigorous testing where numbers and facts
are clearly evident. You JUST CAN'T do that on the STREET. There are no
numbers on the street, no measurement of a baseline nor any improvements
you might make. There's no measurement of a drivers' skill outside of,
"did you win or didn't you?"
I didn't come to the track with the expectation of MY driving needing to be
improved. I was simply getting numbers, so I wasn't a tree-nazi like I was
in the Friday Night No-Lift-To-Shift video. There was more incentive for
me to just not red-light and see what she'll do.
This evening I didn't feel like the track crew were on their A-game.
Sometimes they held staged cars for an inordinately long period of time...
which once I'm staged, I'm on the rev limiter, and once they left me there
awaiting the tree for over 20 seconds, heating my car up and leaving me
disadvantaged out of the hole. Other times they treated the starting
lanes, dried off my opponent's side but not mine, not giving instruction to
hold or wait. In fact, one guy was signaling me forward while another crew
member was standing in front of my car spraying the lane. What do you
expect for only $15? I'm grateful for them, but the communication could
stand improvement over what I saw tonight.
Perhaps I'm just a bit miffed with my setup and looking for someone else to
blame? The track officials certainly don't deserve any for how it ran this
Wheels, Plastidip and Mickeys
What starts as an innocent venture into wheel painting ends in a sticky,
sticky episode of badassery.
Plastidip is spray-on rubber. This is the first time I've ever worked with
My review: It comes in colors but my favorite is black. It's good stuff.
What I did should have had me spraying it on last... because mounting tires
will remove it from a wheel. Most people doing this painted their wheels
while tires were mounted. This is what happens when you don't. So what?
It's spray-on rubber. Spray on some more and you're good.
If you want the BEST results with it (since it can be expensive in some
regions), allow no less than 10 minutes between coats, and spray LIGHT
COATS. That's capitalized because squeezing out a light coat of spray-on
rubber is much easier said than done. It's like lightly-spraying Silly
String, or setting your fire extinguisher to "low". Or trying to bathe in
a waterfall with good intentions, but getting knocked on your ass by the
force of falling water instead. I'm amazed at how easy a product like this
is to work with in concept. It sprays differently than paint, but its
application is easily mastered once you get the feel for it. I give it...

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 Elantra
cylinder head. Good luck finding another one like it. (read more)...
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
Why the Lovell factor is important:
Lovell gas factor calculator:
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!!!
Hyundai Assembly 5 - Fighting The Valve Clearance
In previous videos I showed the 2 factors that really need to be
scrutinized. Valve clearance and how you degree your camshafts. Of course
we got sidetracked with plenty of other tips and tricks but I wanted to
upload this video to illustrate that the process really isn't as easy as
the animations, demonstrations and explanations make it look. The
reasoning is sound, but the work to execute it can be very tedious.
Setting up the valvetrain on this engine was very tedious. I say "was"
because following this video, we can put that whole topic to bed. This is
what it took. Not many people have the patience to deal with this, and I
wanted to showcase here for those who are at the peak of their frustration
with their builds. This kind of stuff can happen to anyone. Let my pain
and suffering help you not feel so all alone.
My apologies for the lack of new groundbreaking technical info. It's not a
complicated task to install ARP head studs, and that was my plot twist.
There are a couple of hurdles you may encounter depending on the production
year of your engine, but they're well illustrated in this video. I'm not
sure if their installation warrants a video all unto itself, but if you
feel it does, speak up because I have 3 more engines to build. I can still
I just wanted to demonstrate that progress is being made on this, and
despite the long breaks between uploads, a LOT is going on behind the
scenes. This was 20 hours of repetitive work and I hope it's at least
mildly entertaining. For me, this was the most boring video I've ever
edited here because I had to re-live the same steps so many times, over and
over again. I could very easily have inserted an hour of it in the wrong
place and nobody would ever have known because it all looks the same. The
text overlays are there only so you can be aware of what's different. A
voiceover would have been pointless because the techniques illustrated are
discussed ad-nauseum in the Cylinder Head 205 and 206 videos. The valve
cover gasket installation process was covered in "Valve Cover Modification
and Polishing", and the discussion about compression ratios is explained in
"Calculate Your Compression Ratio". If you like the job the parts washer
did, check out my DIY parts washer video. ;)

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)
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.
4g63 Balance Shaft Elimination - bearing modification
This is the first part of a two part series about balance shaft elimination
on 4g series engines. This video details the bearings, the other video
will cover the front case modifications. I've already got a low-def video
of the front case mods, and I plan to re-shoot that one in HD when I'm in
the assembly phase. It's linked in the video.
The balance shafts are designed to cancel out harmonic vibrations caused by
combustion and the spinning rotating assembly. They may offer a greater
degree of comfort to the driver and passengers, but with that comfort comes
Often, when a 4g63 timing belt gives up, it's because the balance shaft
belt breaks or comes loose and takes the timing belt out with it. When
that happens, it can total your pistons, valves, damage the crankshaft,
wrist pins, timing belt tensioner and crank angle sensor. Basically, it
can total your motor. The balance shafts also have a combined weigh over
10 lbs and both are driven off the timing belt making them additional and
heavy rotating mass. If you've got a lightweight flywheel but still have
balance shafts, you have your priorities mixed up.
So here's what you do with the bearings. It's easy. You can do this at
home. You CAN do it with the motor in the car, BUT DON'T. You must enjoy
punishment to do this like that.
The end result will slightly increase your oil pressure, but usually not
enough to cause concern unless you have a full-circumference bearing turbo, ball bearing turbo--with your oil feed coming off the oil
filter housing. The head feed would be better in that case because it's
regulated at 15 PSI.
Hyundai Assembly 6 - Manifolds & Turbo
I love music videos. They're so much easier to narrate. I don't want to
upset anyone by not providing commentary about what I'm doing or where this
build is going... and this is the video where all that stuff comes
together. Quite frankly, I missed you. I really enjoy these little talks
In this video is a little fabrication, maintenance, comparison and
assembly. Un-boxings, cleanup, break-fix... Variety! You know... The
stuff that keeps happening as you wrap up any build. It's not a longblock
until it has manifolds, and a turbo
build has a few more things than just that in order to make it complete.
My attention has now turned towards preparing the chassis and accessories
for installation and I promise there will be more involved videos following
this one for the hardcore auto techs. Whether you're watching or wrenching
on this one, all this stage does is create anxiety for wanting to hurry up
and finish the install, but don't rush. Do it right!
These are the non-reusable parts for the turbo install. ALL of the other part numbers in
the video were shown:
MF241255 x2 Oil Drain Bolts (upper)
MF101229 x2 Oil Drain Bolts (lower)
MF660031 x2 Oil Drain Gasket (washer)
MR258477 x2 Oil Drain Gasket (flange)
MF660064 x2 Oil Feed Crush Washer (turbo)
MF660063 x2 Oil Feed Crush Washer (head)
MF660065 x4 Coolant Crush Washer (turbo)
MD132656 x4 turbo Bolt (M10 x 80 x
MD132933 x8 turbo Spring Washers
Thank you all for keeping up with this build. Thanks especially for the
kind comments and interest in this project! You guys are the best!
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:
There's also this at EvolutionM:
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.
First ebay 20g drag passes
I made 2 passes. On the first one, nearly everything that could go wrong
did. But I'm a persistent bastard. I fixed it all, found everybody and then
made this run. It wasn't until after I got home that I realized I had no
in-car video footage of the first run when I broke despite having set it
up... I kicked the alternator belt off no-lift-to-shifting into 4th gear
around 800 feet and coasted to a 13.3 at 82mph against a 10 second Mustang. Overheating with no power
steering I limped it back and put the belt back on, only burning myself 9
times, and then got back out and made this run. The guys in front of us
broke, too. I guess it was contagious? This run is on 93 octane pump
gas. I shouldn't have been in such a hurry. It left me a little
unprepared. You learn things about other things while doing things--is the
best I can explain it. It didn't knock at all, so clearly the new injectors
are working fine... but I didn't take time to burp the coolant system, so
it ran hot. My alternator belt was loose, and it bailed on me. I was
focusing on explaining the video (I deleted that scene from frustration)
rather than putting the car back together, and failed to plug in a very
important sensor. I would have caught it, but didn't get a chance to look
at the logs until I got home. I have to operate so many pieces of equipment
in addition to actually driving that it's very distracting. The guy in
my second race had a beautiful 1967 Dodge Dart, and he was a very good
sport! It was a great race where adrenaline is involved, and I was focused
but wary of whether or not the alternator belt would stay on. I really
appreciate the guys that keep old muscle alive. That car's almost 50 years
old. That's making history right there... He cut a great 60 foot after they
cleaned up the track, but I wish that car didn't break in his lane prior to
his pass if it was a problem for his run. I tried to leave nothing out
and keep it short & sweet. I was lucky to have a track-side cameraman for
the second race. Thanks Taylor! Having that sensor plugged in would have
left me much more confident in the log data and offer a much better
assessment of this turbo, but it is what
it is. Here it is...
Grinding Oil Return Channels
I started cleaning the rust out, and got carried away. I didn't want to do
as extensive of a cleanup job as I did on the GSX, but still wanted to make
improvements because of the kinds of oil-related problems it experienced.
There's a method to this madness. It will make more sense once I get
around to bolting the oil pan back on. The techniques in this video are
things I had to do right now if I was going to do them at all. Some of
them really needed to be done anyway.
You really don't see people do these tricks on imports. Just because you
don't see it, it doesn't mean it can't help. I hope you enjoyed the motor
oil drag races in the middle of the video. They speak for the science
behind this mod... without having to get all scientific. Those results
speak clearly for themselves, and there's plenty of chances to get
scientific as the Glyptal treatment of the GSX is completed.
In this video...
I used steel wire cup brushes for both an air DIY grinder, and a Dremel to
remove the rust.
I used a cone-shaped carbide double-cut burr to smooth the crankcase.
I polished the crankcase with coarse and medium sanding rolls for both an
air DIY grinder and a Dremel.
I used a 1/4" ball carbide double-cut burr to grind the channel.
I used a pack of Harbor Freight #95947 10-Piece Tube Brush Kit.
Hyundai Assembly 3 - Head Assembly & Specialty Tools
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.
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.

2g 7-bolt 4g63 Engine Removal & Disassembly
Tearing down the GSX to see what broke, and what I need to buy. Sitting
for a year and letting the battery drain took a toll on the polished
finish... and it looks like a piece of 4th gear wanted to take a look at
the outside world. Holy transmission case, and it's off to TRE to see
what's salvageable. Looks like the clutch could stand to be replaced, too.
Timing belt has taken some abuse from the higher rev limit and I was
expecting that. EGT probe is fried and I don't even care. Since I'm
running DSMlink and can log Boost,
I'm removing all my gauges anyway. Front case seal (freeze plug) is
leaking a tad, and the crank seal shows signs of excessive crankcase
pressure. I'm going to make some changes... I've got a lot of other
tricks up my sleeve, so stay tuned.

the ECU and the Wideband sensor. No spoilers. :P Fine, I just ruined it
for you. The rest of the video's in the edits and will be out soon. Those

What's not explained in the video, I'm sure is on Wikipedia. For instance,
Installing an eBay 20g
I'm reviewing an ebay 20g TD05 internally-gated turbocharger. You've seen me open it, assess it,
and port it. Now I'm going to install it and see how it fits on my car.
Its dimensions are close enough to a Mitsubishi turbo that it fits well, but it didn't play nice
with my aftermarket stuff as the video illustrates.
You'll see what I mean...
The wastegate actuator nipple aims straight toward the compressor housing,
and I don't like it. I fixed it with a pair of pliers and an allen wrench
at 5:55 in a way that's far less likely to break it. The flanges and bolt
centers lined up fine and without any issues, though others have claimed to
have had them with this turbo. The
compressor cover is an obvious giveaway regarding identifying this turbo. It does not wear the cast-in designation
TD05H that the Mitsubishi turbos do, but
for $228, what do you expect?
If you chose to go this route, just manage your expectations. Be aware
that it might not bolt up perfectly to your particular car, and be willing
to fix what isn't perfect.
