Product Description

WR 2.2 Engine Kit

The newest version of the WR 2.2 is the result of over 15 years of experimenting and development with big bore and stroker version of the Porsche 356/912 Type 616 engine. It has been developed as a complete package that is super reliable and can be assembled by most Porsche mechanics without special tools or instructions. Machine work is necessary to accommodate the larger 91mm cylinders in the case, but no internal clearancing is necessary for the longer stroke crankshaft.

Current testing shows power between 155 - 160 hp and torque numbers in the same range. The new WR2.2 hasn't been developed with only peak power in mind. The goal has always been to provide usable power throughout the RPM range. Average power between 3500 and 5500 rpm has always been the target. 

The newest version has improved power in the mid and high rpm ranges, while still providing the same incredible low end torque and throttle response. Details of the engine kit are outlined below.


  • WR 84mm billet crankshaft rated to 700hp $3150
  • WR 4130 Gland Nut with Oilite bronze pilot bushing $75
