Hi,
Iv got a 2004 wrx sti wr1, iv had it decatted and remapped to approx 330 bhp with matched torque.

Im going to get it dynoed next week and will update with results.

What would i need to get it to 380 bhp? Or 400 bhp?

Prices and parts list would be greatfull.

Thanks in advance

sti Top mount is sufficient for 400 bhp as is the std airbox. 550 pinks will run 400 with the addition of a FPR..

the 2.0 sti motor has been known to run up to 450 happily
