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.
Blueprint 108 - inspect the deck
There's a reason why there are no subtitled specifications in this video
for the block. It's because they don't exist in either service manual, 1g
or 2g. You're not supposed to remove material from a block on the deck
surface because it has ill effects on parts of the combustion chamber
geometry, and alters your compression ratio. It can be done intentionally
in some cases for a desired side-affect, but if you have to deck a 4g63
head, it would be advised to use a thicker head gasket. The Mitsubishi
Multi-Layered-Steel or MLS gasket is slightly thicker than the OEM
composite gasket. Also, HKS, Power Enterprise, Cometic, and other
performance brands all make MLS gaskets that are .065 and thicker.
THERE IS ONE ERROR IN THE VIDEO. I said a block with .002" warpage is
junk. I was completely and totally wrong. While I don't wish to spread
misinformation, I don't think it's a big enough error to warrant re-editing
this video. I just wasn't paying attention. .002" warpage on a cylinder
head is the service limit before it needs machining. I meant to say
.02"... or two HUNDREDTHS (not thousandths) of an inch.
...and here's my justification...
A warped block to me is junk either way even if its minimal because your
MLS gasket will never seal unless both the head and the block are perfectly
flat. Trust your machine shop to get the values for how much is taken off,
and buy the correct thickness gasket for your machine work.
A factory head gasket (composite) is .051"
The MLS Mitsubishi gasket is available in the stock .051 and a .062"
Cometic makes gaskets up to .072"
There are some brands that go as high as .127", but I'd have thrown both
the block and head away long before then.
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. ;)

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
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.
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.
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!!!
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.
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)
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
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
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.

Good luck finding info about this using Hyundai and Kia in searches.

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

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.

GSX Startup (Nov. '09)
I wanted to deliver a video without my normal beats and fast-forward edits.
I wanted to represent this moment for the subscribers, fans and friends
exactly the way it happened.
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...

Hyundai Assembly 10 - ECMlink Install & Speed Density config
I wasn't paid for or asked to make this video. Whenever someone makes a
product that improves one's quality of life and experience... and I buy it,
then you see me use that product on my channel because that's just what I
do. This video is just intended to be my ten cent tour of how easy it was
to install ECMlink and to configure my 92 Hyundai Elantra for Speed Density
airflow metering. Really I just followed directions that were on the
ECMtuning website, and you should always follow the manufacturer's
recommendations over mine. I just wanted to show this one off because...
1) I love ECMlink.
2) I get lots of questions about what software I'm using in my videos.
3) I collect tools. Though some people call this a "mod", to me it doesn't
stop there. This is a diagnostic tool. It's a tuning aide. It's a
data-logger. It's a power-adder and economy Booster. It's a complete engine management
solution that doesn't require cutting or soldering a single wire on your
electrical harness to use it.
But fourth and most importantly...
4) I've always had a great experience with this product as well as all the
awesome people who make it and support it… I'm very grateful to Dave and
Tom, especially for attending gatherings, events and Dyno days to give back the
community. I'm thankful for all the contributors in the forums who
continue sharing their knowledge.

jjrock5's ECMlink install on a 2nd generation DSM:
My personal testimony:
10 years ago, I won DSMlink v2 in a raffle at the DSMCA GT9 gathering. Tom
was there giving away an ECU. Somehow my number was drawn. I won it. It
is the holy grail of raffle prizes at a DSM event, and any one of the 10
people who have ever been so lucky will all tell you this.
In 2005, I had been using the MAFT system for fuel tuning and I was beyond
ready for something new because I wasn't getting the results I wanted.
After installing DSMlink, the car's next journey was a DSMCA Dyno Day where once again, Tom
was there supporting entrants with their tunes on his product. By the time
the 6th pull was over, Tom had dialed in EIGHTY horsepower at red line that
I didn't previously have. The car used to peak and fall off, but the power
curve peaked and held all the way to red line afterwards. The video
doesn't lie, but sadly it was captured with a potato cam. The before/after
results were astounding. The one who's vociferously surprised by the
before/after in the video - is Tom. While peak power did not increase,
there was a 33% gain in power output at 7000 RPMs.
Without DSMlink: https://www.youtube.com/watch?v=7dZRjkpX5Lk
If you look at the order page and balk at the price, something's wrong with
you. If you were to divide the price of ECMlink by the number of features
it contains, they would cost only a few cents each. If you compare it to
stand-alone solutions, it's an outright bargain. Of course, if you own
ECMlink already, then like me... you feel sorry for everyone who doesn't
have it unless you're racing against them.
Some of the electrical procedures outlined in the factory service manual
require special tools which are now antiquated and/or discontinued, or the
procedure is rife with complicated processes to do simple tasks (setting
the idle speed for instance). You will never see me follow the FSM methods
for these tasks in my videos. I am going to grab my laptop, plug in my
ECMlink cable and check the box or button that gives me easy and immediate
solutions to my problem. I offer no apologies for this. If you're here
because I sent you the link when you asked me what software I'm using, I
hope you feel I've done my very best to answer your question.
For the patient people who watched all the way to the end, that link goes
to a video that is not public. That is your reward. Thank you all for
your time and attention, and especially, Thank You Tom! Thank you for your
contributions to the DSMCA community that built me. Thank you for the
raffle. Nothing happens by accident. I won my first ECMtuning product,
you gained a life-long customer out of me, and this video is my way of
saying "thanks" for all you have done to help our community thrive on race

Cylinder Head 205 - Degree DOHC 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
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
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
