Flywheel for 914-6 - Use existing or buy new? Options

[patssle]

I have a 3.0L (separated from a 915) that I will be connecting to my 901 trans to install into the 914. I know the two options are to use the current 3.0L flywheel and get the KEP ring-gear. The other option is to just buy a new KEP flywheel that has the ring-gear already on it. I am running carbs so I do NOT need any sensors/timing.

Are there any reasons why one is better than the other? A new flywheel is slightly (not much) more expensive, but you get a whole new flywheel. The 911 clutch is slightly larger (228mm) but the Stage II 914 KEP clutch is 215mm but seems more than adequate (270 ft. lbs. of torque).

Thanks!

The 901 transmissions in our 914s use a pull clutch too. The plastic pulley mounted to the side of the case reverses the direction of the clutch cable pull to allow the use of the same basic clutch throwout mechanism used by the 911 901 boxes. The 915 transmission used with the 3.0 911 engines also used a pull mechanism, but had a over-center helper spring down on the transmission and also one on the clutch pedal to make the effort required to operate the clutch more uniform over its travel. Only the '72-'73 911 901 boxes used a push mechanism to operate the clutch. It is possible to adapt that linkage to the 914. Stoddard did that on his 914-6 that was described in one of the "Up-fixen der Porsche" books from the PCA. Most people who have gone to larger 911 engines in their 914s have just stayed with the standard 914 clutch linkage, which works fine.
