Have you seen a 915 tranny swap thread?, With pictures would be great. Options

OK,

I screwed up on another board and gave very incomplete data to someone.

I can't find a 915 swap thread using the search function.

I am looking for a thread that explains ALL of the issues with this conversion.

If you guys know of any thread on any board.

Please let me know. I really want to help this guy get it right.

Thanks fellas,

Clayton

Having both a 914 issued from the FACTORY with a 915 transmission and one next to it with an aftermarket 915, I would NEVER have anything but a 901 in my 914-6 (of course this has nothing to do with the V something conversions)

We worked a long time to make the 915 shift as perfectly as possible in a 914-6 and retain its original look. To begine with the wevo intrudes upon mounting ANY muffler on the car so it is out! The vellios is an old casting and has to be massaged with a little machine work for a more precise shift. Using it also means an electric speedo and pickup cut into the side cover as when the ring gear and pinion is swapped the pickup has to go on the opposite side. We experimented with moving the clutch roller assembly sideways for best operation but dumped it in favor of our custom made aluminum part that allows a pull clutch, eliminating the roller assembly while still using the 915 helper spring assembly and pedal 911 pedal cluster with helper spring. These are necessary for a reasonably pressured clutch release. The 915 also has to be spaced down as not to hit the trunk floor, and 914-6 transmission mounts are used. The shifter is another matter: Jim Patrick makes his own shift kit that is a serious departure from any factory piece, but we use a conventional setup that includes all bolt in parts and two parts fabricated from factory parts. They include a stock factory short shift (NOT aftermarket SHORT SHIFT!!!!!!) 70-72 tunnel bar, front 70-72 shift adjustment collar welded to the end of a 73-76 tunnel bar, and a rear 73-76 bar perfectly straigtened to 39 ''. The cv axles are the stock 914 ones and bolt right in with no modification. This setup bolts perfectly into the vellious 916 transmission conversion, and shifts the best we could EVER achieve, allowing one to shift very quickly and precisely at track speeds. This setup also necessitates the use of the rich johnson bulkhead mount as the so called "quick six" mount does not allow for the shift rod to be removed without lowering the engine!!!!!
Conclusion: Clutch works very effortlessly, transmission shifts smoothly and quickly, the electric speedometer is accurate, and the original 73-76 914 transmission and shift linkage is still superior!
