anyone know a bbs with a buick grand national gns or gnx forum? i know this isnt third gen related but i cant seem to find anywhere to post my question about this car......its not MY car so i dont know the exact mods, all i know is, its heavily moded....and for somereason when it gets 2 psi of boost it starts detonating and blows head gaskets like a ****.....im thinking the waste gate isnt releasing the boost that OR the air going into the cylinder is WAY too hot somehow.......i dunno i know pretty much nothing about turbo so let me know if anyone has any insite as to where i can ask my question....sorry about posting non thirdgen content...

If he's blowing headgaskets at 2psi something is very definatly majorly wrong. Should probably make sure that the fuel pressure is rising with the boost. TR's came with crappy fuel pumps, and are only worse now. Might need to replace the pump.
