I thought GT35Rs would be a great choice for turbos. Are you saying that the compressor is to big? Its a T3 turbin housing right? I have lots to learn about turbos. LOL

Those are reall nice turbos, but have safe power capability of 1360 hp! That is way more then most will ever use. The downside to running a turbo that is too large is you typically lose efficiency in the airflow range your engine is requiring. They will also spool slower then a smaller turbo. Those turbos probably have a t4 turbine housing and most likely are a p-trim turbine shaft.You want a T4 housing. He really did not give a ton of info. Those turbos would be best on a real large motor due to the large A/R ratio on the housing. The A/R on a ls1 twin setup should be no larger then .69 AR on the turbine side. A 60-1 HI-FI is a wonderful T4 based turbo that is amazing to about 1000-1100 hp. I would buy through someone like precision or innovative. They use Garrett parts to make a superior turbo.

Thanks again man. I guess I loosing that auction turned out to be a good thing. LOL I cant wait to start building headers and all the pipiing. I made a intake pipe for a vortech Supercharge on my FFR cobra back years ago and it looked awesome. Im thinking of having everything ceramic coated black and painting most of the engine parts black. That would go well with black interior and black Exterior. The project shall be called Black Out. LOL
