first : are you guy using wastegates on your turbo setups or running them straight to the carb?
1) The wastegate goes into the exhaust ("hot side") and bleeds off exhaust pressure (before turbine) when you reach the boost you want. It isn't plumbed into the "cold side" anywhere.
where are you getting your turbos?
2) Try to stay away from places that seem too good to be true. There are a lot of junk Chinese made Knock-offs out there that you DON'T want ANY part off. Be very careful what you look at.
A good turbo shop won't steer you wrong!
www.majesticturbo.com has always treated me well.
I have bought brand new Garrett turbos off of ebay, but I stay away from used stuff because you never know for sure what you are getting until its in your hands (and then you probably have to rebuild it anywyas)
The Master Power turbos (
NOT "power master" or "xs power"= chinese) are good quality and are made in Brazil.
and third what size turbos are yall using? im thinking like a T3 or something of that size[/quote]
I have a TO4B with a S-3 trim compresser and "O" trim turbine. - check my sig
