Help with alpina turbos
So I received the ebay alpinas and had one diverter valve bad as soon as I installed. I swapped with one out of my Garrett 2256, the stock n63 turbo, and got it driving but the boost between banks is insane. Bank one with my 2256 diverter valve is right on target, but bank 2 is anywhere from 3-6 psi higher. I marked the wastegate and tried to get closer but ran out of room on the rod to loosen it. Could it really be the diverter valve causing this, I assumed it played no part until releasing boost when you let off the throttle. I have two new ones on the way, but the only issue I have is the imbalance. I went to make the diverters matching from my old turbos and find my second diverter valve ripped to shreds. I bet that’s why I could never get my boost up like I could a year ago. Any advice?
