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..
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.

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.

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"
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.
