I've spent some time attempting to research my question and cannot find any information in the forum's archives; so,thought that I would ask my question on this forum.

I am doing a conversion project to install a 1987 3.2 motor into my 914. I plan on using the 901 transmission. In the process of researching parts to make this installation, I came upon a Kennedy pressure plate with a 225mm clutch disc that was essentially new. The owner stated that the part is what I needed to make the conversion mentioned above. So, I purchased the pressure plate and disc from him.

When the hardware arrived, I found that the pressure plate included a ring gear for the starter. My confusion is in noting that the flywheel currently mounted to my 3.2 motor has an integral ring gear. So, do I have an incorrect flywheel or an incorrect pressure plate? The Kennedy design included a removable ring gear for the pressure plate. So, do I simply mount the pressure plate to the 3.2 flywheel WITHOUT the ring gear? Or, is the Kennedy ring gear positioned to mate up with the location of the starter motor on the 901 tranny?

Sorry for the confusion, but I am just trying to understand what is required. Incidentally, the 225mm Kennedy clutch disc appears to be a perfect fit to the 3.2 flywheel installed on the motor.

OK. Yes, the 3.2 has a 9 bolt flywheel. The flywheel that is on the engine does mate up perfectly with the Kennedy 225mm disc. I am assuming that the spline count on the disc will match the output shaft of the 901 tranny. So, my question becomes one of knowing if the starter gear will mate up with my existing 9 bolt flywheel (with integral ring gear) when the starter is mounted to a 901 gearbox. If the answer is "yes" then I guess that I just mount the Kennedy pressure plate WITHOUT mounting the ring gear to the pressure plate that was supplied with the plate assembly.

Incidentally, if someone knows the spline count on the 901 or other data that would allow me to confirm that the 901 will fit the setup I have, please provide that data.

Also, does the same pilot bearing work for the 3.2 flywheel as for the 2.0 liter four cylinder motor?

Have you considered the motronic angle in all of this? I am doing exactly the same thing, and wonder if the integral ring might be for the sensors. Took a bit of a hogging cut to make the 901 fit with the tdc and velocity sensors in place. Then the kep stuff comes into play as an add on. Have to admit I am only part way there - I still have seals to replace. Sounds like you are ahead of me, but I am finishing the fuel lines and have the mount installed. I sooooooo want to hear the 3.2 come alive!
