My turbos recently grenaded and I need advice on whether to rebuild, buy reman., or possibly used. I am positive the rebuild will be extensive because the turbos now make a high pitch noise, meaning the are probably unbalanced or hitting the housing. Thanks in advance for any help

 

imo, it's a good time to get a power fc and go single.

 

Do you still have any boost? If so what is it 10-8-10 etc.? High pitched whine will probabley not mean the housing is being hit by the compressor blades. More likely a bad bearing but not likely both turbo's unless the oil passages are plugged. Rebuild is a good way to go about $150 each turbo if you do it yourself and you get new bearings.
