Hi, can anybody help me with some information, I need all possible technical info on the BMW 333i.I am busy working on it and I want to change the diff. But I need to know the ratios to see if i can fit the diff of a 323i e30. I have put a racing clutch, gas flowed it etc.. but now I am stuck with the diff issue.

Hi Niek,

Sent you a PM as well. The diff is a 2.93:1 unit and a stock 323 one will make matters even worse considering the direct 5th of the Getrag 265/5 that was std. Contact me for more info.

Cheers
