Hi all,
I am close to pushing the button on an SR20DET conversion into my E30. I won't be going crazy initially, just putting in a stock blacktop with FMIC, intake, exhaust, EBC.
I am wondering what diff ratio to go for? I have read on E30 based forums a lot of people like 3.25 or other similarly long ratios. However my mechanic has recommended 4.1, i assume because this the 'middle of the road' stock ratio for S-series cars that the SR20DET came in.
I've owned 2x SR20 powered S13's so i know how they go. i quite like the short and sharp 1st - 2nd. Plus i would rather low down power than long top end just as i see it being more useable. However seeing so many turbo powered E30 owners saying to go for lower ratios has me unsure.
i would be interested to hear people's thoughts, especially from those who have SR powered E30s.
cheers,
Ant
