Whats a good rear end ratio for a turbo car? currently have 373s,, want the car to be in the deep 9s and still be decent on the street, car is an 01 z28 a4

 

I am going with 3:90's

 

If you're looking to go deep into the 9's with a turbo setup wouldn't a ratio in the lower 3.xx's be best suited?

 

This question would be better suited in the FI section but just to give you an example, 98z28cobrakiller on here has gone 8.98@154mph on a 3.50 gear with a th350 trans. Another example is cablebandit, he went 9.29 with 3.08 gears. You don't need much gear for turbo setups.

 

My buddy with an RX7 has 2.70ish gears and it runs hard, granted its ALOT lighter than our cars. Like said above you don't need much gear for a turbo setup

 

thanks for the response's thinkin a 3.08, 3.23. or 3.55

 

I run a 3.50 in my 9".
