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.

DSM 4g63 Engine Build
This is the video I made for the rebuild I did on my 1995 Eagle Talon TSi
AWD. It took us over 6 months of hard work consisting of many almost
sleepless nights, and countless frustrating moments that almost made us

Removing the head of a 4G63 in 10x speed.
The project got delayed a few months. After finishing it and cranking it
over, Interference in the cylinder was discovered. Shamefully, I admit my
mistakes were: 1) Not putting the spark plugs in immediately after
installing the head. 2) The bad habit of using my Valve Cover as a parts
tray and 3) Putting off the project too long, so I didn't recognize a
missing bolt from a custom fabrication.
The head needed new valve seats, valves and some welding. Wiseco and the
machinist both thought I'd be OK running the piston after smoothing out hot
spots, but I ordered a new piston not wanting to risk the deep gouge in it
with the high Boost I plan to run.
Peace of mind is priceless.
The danger in being over confident is sometimes you skip triple checking
stuff. I've built that engine at least 5 times and got careless.

4G63 Dragster - First Track Day
Atco Raceway - 4/18/09
First day at the track with our 4G63 Dragster project. The converter is
too tight to build Boost on the line
at the moment but we're working on it!
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.
