ive got 3.3 cylinders and pistons on a 3.0 making it a 3.12
you can probably find some pretty cheap.
Getting higher rpms then the longer stroke, i guess makes the engine consume at least as much air or even more then the 3.3.
Con is that the heads probably gets warmer from the higher rpm, and is a thing im concerning about right now as iwe now converted mine to EFI and get more power.
My engine ran on 1.2 bar with a k27/k29 before so i think with more fuel it should run cooler on EFI then on CIS or?

Anyway ive been running on singel spark (temperature) and titanium retainers (dont know what kind of valve spings) and iwe been way over 8000rpm several times when i just got the car (which is where my gauge stops), but after i while i made sure to not go over 8000rpm. (no rev limiter before efi)

I havent realy pushed the car on efi yet as i know my 915 transmission is the first thing to break, and i dont know what my internals can take in heat and power.
Right now my sachs performance clutch slipped in third as soon as i got boost on 80% throttle :P

Looking for a reasonably priced 930 transmission now. anyone?
