Long story short but my rear turbo seal blew out, I purchased 2 turbos that had the steel wheel conversion and had been flowed and ported. After a long night of doin the swap only to find out the seals in the front turbo I purchased where kaput. So after another lengthy period I installed my good stock front turbo and an running the larger rear turbo. The only issue I have is until about 7psi the rear turbo flutters due to the boost from the already spooling smaller front turbo acting against it. I want to know if I'm causing any damage to my rear turbo by driving with it like this because it's going to be a while before my turbo gets rebuilt
