Hey guys im wondering about the 4g64. i can get my hands on one for next to nothing. its a sohc injected 4g64 non turbo. is this the only way these engines come out? or do they come out stock dohc? and turbo?

The sohc is what you usually find, the dohc is not as widespread. There is no manufacturer turbo 4g64 from what I know.

You can also have found a narrow block, or wide bloc so be aware of that. I've run into several narrow blocks lately because the cars they come in are showing up at the salvage yard.

Here's the list to figure out what you have found. http://projectzerog.com/mitsubishi_engines.shtml

Here the one that talks about turning it to DOHC.

There was only one year and one specific model of 4G64 that was DOHC. The 1994 Mitsubishi Galant GS, however, any DOHC from a DSM will fit onto a 4G64 block with some minor modifications. You have to know what your are looking for to make your swap viable though, sensors and plumbing vary between years.

To elaborate on what JD posted, the Narrow Block 4G64 will be found in all FWD, and AWD vehicles, while Wide Block can only be sourced from RWD trucks and Vans. The difference between the two is the width between the mounting holes on the bellhousing, a Wide Block will not bolt up to a transmission designed for a Narrow Block and vise versa.

Thanks guys. is there any diffrence in the actually engines running and HP compatibilitys in the wide and narrow blocks? or is it simply only diffrent for the diffrent types of transmission. from what i no it was in a 4wd van. so narrow block?
If i were to get it would i need the engine harness and ecu from the van?

also when doing a sohc to dohc swap im geussing youd have to go to a dohc ecu?

The Wide and Narrow blocks are identical other than bolt spacing for the transmission.

What are you trying to swap the motor into?

As for your block, if it was an AWD expo "van" then its Narrow block, if it was a 4X4 Space Van from the Late 80's its Wide Block.

The wiring and ECU you want depends on your ultimate goal for the vehicle and the configuration you set it up for. If you want to run a turbo setup, you will want to source a wire harness and ECU from a DSM (All Turbo DSM's are DOHC).

im not sure atm ive been keen on the idea of a rwd colt, or if i were to keep it 4wd just build a drag or street early evo!

Id definatly run the engine turbo and work all the internals, but atm its all only an idea as im still doing my 4g63t rwd conversion!

In NZ we have a Mitsubishi Chariot (1998) it has 4G64 Dohc(GDi shit box) engine, can these blocks be used in the conversion with evo1 head(dohc 4g63t) if so what about later model 4g63t head from evo4? Thanks guys
