+1 for the RS*R Ran Up, I run it in my Stagea. 450ish HP, 22-28psi where stock is 8-12 depending on gear. Touching 200k kms with out any issues, relating to the motor.
Popped difs, gearboxes and turbos, but so far, the rods have stayed in, so thats a good thing no? Not bad for a stock bottom end VQ
