the turbo on the car? idk why you would want it. its a stock T2 exhaust side with a early turbo buick compressor. its a home made "super 60" with the correct housing. its REALLY nothing special. I think a .63 housing would do WONDERs for the car. if not a hair larger than .63. but i cant complain, the car is AMAZING on the street. almost instant spool, never stops pulling, and it gets great mpgs still. id recommend this comby to anyone with a 2.5 street car.
