Stage 2 SUPERCHARGER KIT for the PORSCHE® 968


Video Available Product Installation Services Available

Taking our 968 Stage 1 kit Up a Notch! Where our Stage I kit was designed for street use, our Stage II kit is ready for the track. This kit provides a new set of four 3rd generation (improved) injectors, a larger crankshaft pulley, and brings in significantly more boost. This is an advanced kit for the experienced tuner. Because of the higher CFM air flow provided, changes will be needed to ensure an adequate fuel supply.

Yet, there is no need for intercoolers or special head gaskets. In fact, the engine does not have to come apart at all for this kit! Even the Air Conditioner stays!

The Results: Our 968 Stage II kit will produce almost 350 HP of safe, reliable, trouble-free HP on your 968.

Top Technology! The 928 Motorsports Supercharger kit for the Porsche® 968 will provide more horsepower and torque and do it efficiently, reliably and quietly with no loss of drivability or daily ease of operation. You will substantially increase your 968's acceleration and fun-factor! This rugged supercharger's precision construction and the exclusive ceramic-coated impeller assures full high speed performance at all RPM's along with outstanding reliability and quiet operation. No special care or maintenance is needed.

Dyno-proven Results: This Supercharger kit installed on a 1992 Porsche® 968 with manual transmission (photos below) produced 296 HP at the tire and 348 HP at the engine, up from the stock numbers of 187 HP at the tire and 215 HP at the engine. A gain of 133 HP. Further, the test car was "driven" on the dyno for several hours to ensure belt tracking and tension staid correct throughout all RPM, ranges, gears, and loads.

Some Features:

  • Designed for maximum safe boost at the track
  • Completely street-drivable.

Warranty: These are factory NEW kits and are warranted direct to you. 928 Motorsports warrants against any and all defects in workmanship and material for 1 year from the date of purchase regardless of mileage or use. Raptor Superchargers warrants the supercharger head unit for 1 year, but racing voids their warranty. This is common with most supercharger manufacturers.
