Hi all,

I am wondering if the 4G64 engine would be a good choice for the Locost build. It is a 2.4 L 4 cylinder engine.

I have a mighty max pickup truck with 8 valve 4g64 engine in it. It is smooth and powerful. And I have been working on the engine quite a few times and i became very familiar with the engine.

The 8 Valve 4g64 is for the pickup truck. But the 4G64 engine found in Mitsubishi Galant is 16-Valve. And i heard people put 4g63 head onto a 4g64 block and it makes crazy power.

So my goal for the build is to make somewhere around 150 HP. And use NOS to boost power. It is going to be insane for such a small car.

So galant 4G64 engine with mighty max 5 speed transmission. Any potential issues?

The best advice you'll receive here.. is to use what you know and whats available to you. if you are comfortable with the 4g64 and it is available.. then go for it!

i think the 4g64/4g63 platform would be perfect for this application. your wide block 64 in stock form would not be able to take a ton of boost but even if you planned on 300HP that would be tons of power in a locost.

actually there are wideblock and narrow block 4g64 blocks and the internals all work with either. the issue is the tranny mounts. wideblocks come from RWD platforms, mighty max, pajero, etc. the FWD narrow blocks are found on front wheel drive platforms, eclipse, galant, etc. (the mitsubishi AWD vehicles are still based on the FWD motors)

check out this forum for lots of RWD mitsubishi info.

you can actually use a narrow 4g63 in RWD but you will not be able to use that tranny.

it is possible to get to a good CHEAP fairly high horse and fairly light weight drive train with the 4g63/4 platform though.

(ive built several 4g6x motors and have a 700hp build in the works. plus i have a stock 4g63 narrow block in storage for if i ever get around to building my own locost)

Thanks Zedicus,

I didn't know there are wide blocks and narrow blocks. I thought the only difference was the heads.... Why they call them both 4g64 when the head and the block are different....(Mighty max VS Galant)

But anyway, thanks for the good information. I am wondering what kind of horsepower can a stock wide block 4G64 take? You are right, 300HP is a lot for locost. My goal is to build one with 150 horsepower so it would be a pleasure for road use and add Nitrous when somebody want to race me.... Heheheheh.... I am wondering if the stock 8 valve 4g64 can take it...

Start with Bill Hincher at Japanese Auto Repair in Toledo Ohio.
The same guy that ZeroG had make a mold and start producing 3G and 4G conversion bellhousings to fit the T5 (or was it the W58? I disremember).
Nice guy, I've chatted with him several times. http://www.japaneseautotoledo.com/
He also makes Subie and Honda conversion stuff.
