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.
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
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!!!
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...
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
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)
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...

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
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.
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. ;)

4g63 Block Oil Gallery Mod
This modification is intended to improve your 4g series engine's oil
delivery. People frequently discover large chunks of flash in their
engine's main oil gallery. It's because the galleries are part of the
cast, they're not machined into the block. There is also a very rough
sharp edge where the main oil gallery is bored into the block, and oil must
make a slightly greater-than 90° turn in order to begin its course to the
parts it lubricates. Both of these conditions cause turbulence in the oil
flow. My goal in this video is to eliminate as much of that as I can.
This is a cheap and easy modification if you have the tools, and the
patience. Any engine with cast-in oil galleries could probably benefit
from this. Be careful not to cut into the high pressure oil gallery or
else you will circulate un-filtered oil to the #1 main, oil pump, and rear
balance shaft. You will also deprive the rest of the engine the oil
pressure it needs to operate. So in short, punch a hole in that and it's
trash. I did this my way, everyone may choose to do this a different way.
I just wanted to make this video to raise awareness.
Also, there's a great thread on DSMtuners about this. Pictures and
everything. Written by a machinist and friend of the DSM community. Go
give him some reps because he's posted a lot of great info about the DSM
oil system over the years.
How to build a 4g63 Coil On Plug Assembly
This is just like all other do it yourself projects.
1) Buy parts that make doing the job easiest for you. 2) Put the stuff
together. 3) Install it.
No really, I used the JMFabrications Coil Plate, ordered all new UF269
Chrysler coils and wiring from Toyota. This video is intended to
compliment thread #290665 at DSMTuners dot com which contains wiring
diagrams and part numbers for these specific products.
The only thing I did different was use 3/16" grommets in the harness holes
rather than elongating them to prevent wire chaffing. I went a little
overboard with the convoluted tubing, but it looks fantastic.
you can get coils from Chrysler models...

required. The factory coil pack on these cars is good for 30+ PSI.
Hyundai Assembly 4 - Balancing Rods
I edited this video to its finished state, and RojoDelChocolate handed me a
track with no collaboration that was the right length and rhythm. I
literally did nothing to the video once the audio track was dropped in, and
that's just how it went. I can't believe it. It's like when you're
pumping gas into a Ford F150 full-blast and release the pump handle to stop
right on $80.00 even. He's got more musical talent in his pinky fingernail
than I have mechanical ability in my spleen, appendix and tonsils combined.
Thank you RojoDelChocolate.
Here I'm cleaning up the fly cuts, balancing the piston and rod assemblies
and preparing to double-check my valve clearance. I had to start by
cleaning up and re-lubricating every part that was removed to prevent
contamination of the assembly. This is the tedious part of doing the job
We learned that this whole engine assembly was pretty far-gone in previous
videos, way past its service limits, so making it fit and work again takes
extensive testing, machining, and re-testing to ensure all of the parts
fit. This is likely the most challenging build I will perform on any car
in my driveway. It has been so far. But because I have not demonstrated
the basics of engine balancing beyond what a machine shop has to do to zero
balance a flat-plane crankshaft, I thought I'd give it its own video right
here with one of the test assemblies.
When you balance rods by themselves, you balance the big-end and the
pin-bore separately. You get weights of both ends of the rod using a jig
and a process that I don't demonstrate in this video. The reason you do
this is because the position of the weight behaves differently relative to
its distance from the crankshaft pin. Weight on the big end has less of an
effect than if there's extra weight on the pin bore. The best balanced
engines have every part of the piston and rod assemblies balanced
separately within .1 grams using the method I just described, and not the
method shown in this video.
The method shown here involves weighing ALL of the piston and rod assembly
components together, and then taking out the difference just on the casting
lines of the connecting rod. They were already off-balance and had never
been balanced before. This is an improvement, not perfection. It's still
something this engine needed to have done. I'm not using the
big-end/small-end method here because these pistons are pressed-on and if I
try to remove them from the rod, it will shatter the piston skirts. No
thank you. I'm not replacing these pistons.
The reason I grind down the casting lines is because it's weight is in a
neutral territory, extending from the big end to the small end. It's
easier to take an even amount off when you grind across the entire length
of the rods. This method leaves a lot up to assumption as there's no way
to determine which end of the rod is heavier, or if the weight is in a
wrist pin or piston. All this does is ensure the crankshaft is spinning an
even amount of weight on all 4 of its rod journals. Grams of weight turn
into pounds of force at idle speeds. My goal is to remove that vibration
at any and all rotations per minute if I can. So I make them all the same
within 1.0 grams of their combined weight.
If you're assembling and balancing all NEW parts, not parts that have worn
together and need to go back in the same holes... you will have to balance
the individual parts and pieces. This is the poor man's method. Even with
the new parts you still do the poor man's method once you're done balancing
the individual parts and assemble them, but sometimes when you're lucky
with the new parts, you can just swap around the rods, pins and fasteners
to balance the weights on each assembly and not have to grind anything at
all. That's awfully nice when that happens. You know the Hyundai won't
let me get away with that.
Removing stress risers might help strengthen the rods, but it's not what
I'm after here or else I would have removed the whole casting line from all
of them. These rods should be fine for my goals. My goal is to remove
just enough from all of the fatter rods (weight wise) to match the lightest
Balancing an inline 4 engine with a flat-plane crank is easy if you have
already balanced the crankshaft. This crank was already balanced for the
GSX motor on a previous occasion. It's zero'd out. In order to balance
the rotating assembly, all you do is make the piston and rod assemblies
weigh identically to its neighbors. Just 3 grams of weight can produce
over a hundred pounds of lateral forces at red-line so this is an aspect of
engine building that you should not overlook. All you need to do is get
all of them within 1 gram. The scale I'm using measures whole grams, so
that's all I can do anyway. This method is acceptable for balancing a
rotating assembly as long as you're smart about how to remove the weight.
Crooked Alternator Diagnosis
Got belt problems? Watch this video. Common issue on Mitsubishis. If you
find your tensioner frequently coming loose, if you have belt squeal
issues, if you kick your alternator belt off doing high RPM shifts, this
video was made for you. This is the first of a 2-part series.
What I do here is take my car apart to confirm the problem, and so you can
see it. Because the alternator is supported by a soft cast-aluminum piece
of the oil filter housing, because the hole is significantly larger than
the bolt, and because the bolt is rough hardened steel... a common failure
occurs over time that can lead to all kinds of belt problems. This video
demonstrates what you're likely to find if the issues in the top paragraph
Tools used in disassembly. 10mm, 12mm, 13mm gear wrenches and a deep-well
12mm socket (just the socket). I used a mini-pry bar briefly to free the
lower alternator bolt.
