I put a series 5 engine and turbo into my series 4 turbo and used the s4 wiring harness and ECU. I have the racingbeat REVTII w/ FCD. i ran great fro about 2 days boosting at 11-12 psi. I took it on a trip to northern VA from southern SC and about 5 hrs. into the trip it started boosting at about 15 psi.. being 250 miles from my destination i had to keep going and sure enough it spiked to 15 psi on last time a the front rotor blew
. pretty sure my waste gate or ABV wasn't opening at all... but i haven't had time to look at it yet...all in know is Okpa on rotor #1. ....amazingly enough it made it to VA on one rotor
