This is the OEM supercharger that comes off the Series III engine that only comes in the '04-05 GTP and '06+ GT supercharged. It comes with the stock 3.8" pulley and boost bypass valve. If you buy a pulley at the same time, we can install it for no extra charge.

To install this on a car with a Gen 3 supercharger you will need the following parts:

• Gen 5 to L67/L36 Throttle body adapter or Northstar TB kit for Gen 5(best option)
• Gen 5 lower intake
• EGR Block off plate "intake" - NOT for the EGR, but to block off the EVAP solenoid port by the inlet because the Gen 3 has a different EVAP solenoid.
• Supercharger gasket - Garlock or stock replacement.
• Lower intake O-rings
• Intake gaskets
• (2) bottles of GM Supercharger oil

This is a used supercharger that we remove, clean up, inspect, and ship out. It comes with no oil inside (because it would leak out during shipping).
