doing a 4g64 build on a evo for track purposes for a buddy. I have a 2.1 fully built and trying to see what he would need for his goals specifically

Just need to know what length rods he would need and a good compression

HP Goal: 500-600 tops probably running an fp green or red turbo to keep the spool for low rpm
Stick with a 2.4L for a little more response out the corners

I have read everyone doing builds for street/drag but cannot seem to find track only information

 

If recommend to stay with stock compression. Running higher will just cause unnecessary problems down the road.

 

I don't know of many track cars running more than 2.2L
You aren't really going to be at low RPM in an evo on the track much

 

I swapped out my 2.4 for a 2.2. 2.4 isn't really that great for track use. Your limited rpm regardless of what people say or do, drag racing you still have to shift into 5th at the end being you run out of revs, road racing your in higher rpm range which will kill the crank. 2.4 has its benefits on the street. Your not over reving on the street and it will give you great tq for whatever. In my opinion the red and green would be to small for a 2.4 anyways. Way more engine then turbo. Your better off with a black.

 

I got TS Comptuned's old personal handmedown 2.4 paired with a BBK 3B, though it's hardly a track car. I never push it for more than 2 or 3 laps in a row so I don't know for sure how it would hold up in a serious competition. Lately it's just autocross where the powerband murders all the casuals who show up, but again these aren't competitive days (so it's not really fair to them, cause this thing just teleports between corners).

this was the motor: https://www.evolutionm.net/forums/pr...ispreloading=1

and this is what it's doing now, retired in california, on a low reading dyno:

does not bog from a launch, I can say that

 

94mm stroke, 9:1 compression. It'll be plenty responsive.

 

Awesome! Thank you

 

Yeah thats what I said lol 2.2
