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 versions 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 at over 155hp and over 150lbft of torque with a stock exhaust system.  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 runs cooler and 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.

COMMONLY ASKED QUESTIONS

Can I use my mechanical tach with the WR 2.2?

No, you'll need to change to an electric tach. We have had customers modify the tach drive front cover for full flow output, and this will work, but it's not common.

Can I build a WR 2.2 with a 6V system?

The answer is yes, and we have had several customers do it. The 6V starter has enough cranking power for the 2.2 engine, but if you're already upgrading the engine why not upgrade the electrical system. You'll need to source a 6V electric tach, and you'll also need to use the very expensive Wosp 6V hi torque starter to use with the 215mm flywheel.

Do I really need the 215mm 901 clutch?

No, not really. There is nothing wrong with having a clutch that is too weak for the engine's torque output. We have lots of 1.9, 2.1 and 2.2 engines using the 200mm clutch.  That said, the 200mm factory clutch is not able to handle the 160lbft output of the new 2.2 engine, that's why we developed the new flywheel to use the 215mm clutch package. 

Will the WR 2.2 make more power with a different exhaust?

The general answer is yes. The WR 2.2 with a 4:1 header system will make over 170hp, but most drivers find this type of system way too loud. The quality and lifespan of the currently available Dansk oem muffler is not great.  The new WR Stainless Sport I and Sport II mufflers are a high quality option for the 356 or 912 and add a little power over stock with a great sound. See the listing on this page for these mufflers.
