Too much boost = blown head gasket
I was toying with a Honda on my way to work last Friday...it sounded something like this:
squeel, vroom, whoosh, shift, squeel, vroom, whoosh, POP!, sputter, shake, puke, silence.
Good thing is I've gotten good at changing head gaskets. Took me about 4 hours to do the whole job
.
Running at 21psi, I was just asking for trouble. It was way out of the stock turbo's effiency and was just super-heating the air. Turned it down to 18psi after the head gasket and it feels just as fast if not faster.
