Garrett TP38 I've got a lead on a Garrett TP38 that is local for $150. Its off a 99-03 7.3l Powerstroke with low miles. Its Specs Should be, .84A/R exhaust turbine housing And compressor side 1.0 A/R. What i would like to know is If that would work good on a Stock LS1 Long block. I'm planning on Starting fab on Front Mount turbo system late this fall and im trying to get a turbo before then. I only plan on 6 PSI on this motor.

Bingo......never was meant to work well on a high flowing LS1 motor. A little worse then even a 60-1 which is pretty much crap at anything over 5000rpms. Minimum, I would suggest a high flowing 70mm with a proper sized exhaust turbine wheel, around ~80+mm or more. The turbine is the most overlooked part of the turbo world...

Alright. Any Turbos Out there perferably of say a stock car or truck that would work good? I'm trying to keep prices down when i can. I know you can't go cheap on a turbo build though.
