For Sale: Cam Driven Vacuum Pump Setup for all Mezger Engine GT3s - Standard on 997.2 GT3/Cup - An Upgrade for 996 and 997.1 GT3's. - OEM Porsche Parts

BRAND NEW NEVER USED.

Improved brake pedal feel and more consistent vacuum supply to the brake booster at all RPMs and Altitudes.  This is a bolt on plug-and-play upgrade for all 996 and 997.1 GT3 engines, and was standard starting with the 997.2 GT3 and CUP cars.   This vacuum pump replaces the driver's side lower cam cover/oil scavenge pump to add the tandem cam-driven vacuum pump integrated into the scavenge pump.  The vacuum hose then runs from the pump to the factory port above.  

This installation can be done with the engine in the car.  The driver's side exhaust cam will need to be timed as part of the installation process.

997 107 022 91 - Cam Cover with combination oil scavenge pump and tandem vacuum pump
997 105 036 70 - Vacuum hose line including integrated bracket

I learned about this modification from @powdrhound who did this mod on his 996 Turbo engine (Note that the Turbo and GT3 vacuum pumps are different due to the higher redline on the GT3, but all other parts used are the same).  He discusses this modification here: https://rennlist.com/forums/996-turb...tallation.html

Asking $1250 shipped to CONUS for this kit.  New cost from Sunset Porsche was over $1500. 

All new parts never installed in original Porsche packaging.  The only thing that needs to be added is a plug of some type to block off the manifold vacuum port that this pump replaces once installed.
