Brand new Turbonetics turbine housing for "Q" trim wheel. Housing is a .96 a/r T4 flange and has a predrilled/tapped spot for checking back pressure. I believe the p/n on the housing reads 0393-81 96. You can see from the pictures that housing is completely clean, never used. Tried to get a pic of the inside as best as possible. Bought it for my car but made a mistake, my car has the newer F1 wheel so it doesn't fit. Asking $150.00, which is already REALLY cheap.
