Here's a short video of my 4g64 with 4g63 head Build-up.
I still need to tune the motor a little as you can see or hear in the video, the motor sounds a little rich specially after 7000 rpms. Dyno video coming soon... Hope you liked it..

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.
RARE 2.6L Stroker 4G63/4G64 Hybrid 6-BOLT Race Engine - 1st Gen AWD DSM
This is the documentary of the blood, sweat, and beers that went into the
2.0L conversion to a 2.6L Stroker engine race car. Built for the DSM
Shootout with some friendly gear heads. Its been for one test drive around
the block and it was a blast just to see this beast drive under its own
power after months of hard work.
THIS CAR IS CURRENTLY BEING PARTED OUT. ALL ENGINE PARTS ARE FOR SALE,
SERIOUS INQUIRES ONLY... HEAD HAS SOLD, BUT THE SHORT-BLOCK IS UP FOR GRABS
ALONG WITH EVERYTHING ELSE LISTED AT THE END OF THE VIDEO. MOST OF YOU GUYS
SHOULD KNOW WHAT THESE PARTS ARE WORTH ALREADY SO PLEASE SEND SERIOUS
OFFERS TO ( firstname.lastname@example.org ) THANKS!

Eclipse Spyder 4g64 Valve Tick Fixed
I noticed nobody has a video of how to fix a 4G64's infamous valve tick...
so i did it myself! For those of you who are experienced mechanics i
apologize for breaking it down so much. The job itself isn't complex at
all, took me about two hours total work time. I hope this helps and if you
have any questions just leave a comment.
The link for the valve lash adjusters is:
If that doesn't work just google "4G64 Lash Adjusters"
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...

What isn't covered in that thread is the necessity of a capacitive
discharge system. In order for this to be any kind of upgrade a CDI is
required. The factory coil pack on these cars is good for 30+ PSI.
4G63 back from the ashes---First half of engine rebuild
After over a YEAR of promises that I'd get this vid done, I went halfway
and got the engine pull and most of the shortblock work edited and
documented. Here for your viewing deliciousness is PART 1! (link to torque
specs for the engine here: http://bit.ly/17KDEED)
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.
4G63 Mitsubishi Powered Mustang - WTF?!
Never would have thought we would see a 122ci 4G63 Mitsubishi powered Fox
Body Mustang when we went
to Georgia for the LIGHTS OUT V drag race (DVD Pre Order -
This unique x275 car, built by CDub Racing out of Louisville, KY caught
everyones attention at the race just by the freak noise that it put out
compared to the rest of the field.

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.
6&7-Bolt 4g63 Front Case & Oil Pump Rebuild
Here we disassemble, clean, inspect and rebuild both popular 4g63 front
cases. This is not difficult, you just need to know what to look for.
Something else that happens in this video is the analysis of one of the
factors that caused my 7-bolt engine to fail. It wasn't the only cause,
and we'll talk about that later, but left to its own devices and without
the other contributing factors, it would have been the only cause.
