can u fit a uk turbo gearbox on a wrx ?as ive heard they have a longer gear ratio .if so how would this afect the performance of the wrx with its larger bhp?

 

mr smash,

The final drive [ diff ] ratio is different on a JDM car to a UK car and it will conflict with the rear diff is the ratios don't match. You need like for like I'm afraid.

We have many boxes from stock call me to see if we can help.
