I just had my stock turbo rebuilt about 3 months ago. I am a little concerned because it seems to be making a strange sound when I really get on it.

If I could compare it to something, I would say that it sort of sounds like a peeny in a jar when you shake it.

It sounds as if something is loose in the turbo, maybe a bearing or something, I am clueless. It only happens at WOT, could this just be a problem in the rebuild, or is this actually something that is common with these cars?

Also the car seems to be missing & backfiring at WOT. I don't think this has anything to do with the turbo making that strange sound, but I am not sure what could be making it backfire at WOT. Any suggestions?

Thanks
 
CAUTION...what you are discribing sounds like detonation.DO NOT go WOT untill you see why car is overboosting...

you got a scanmaster??? if so,whats the KR at WOT?

Definitley sounds like overboosting. Don't get on it until you find out why! Check the hoses controlling the wastegate.
