Boxster 5speed cable shifter for a 915?, anybody think about this? Options

[jim912928]

I'm still gathering parts to start my six conversion in the spring. About the only thing left for me to iron out is the tranny question. I have both a nice 914 side shifter and a nice 915 that came with my 3.2l. I've investigated the WEVO with the 915 (expensive though), conversion clutch package and using my 901 (cheaper but I do like the 915 gearing better). I was notified from someone on the other 914 board that a thread was going on about using a boxster 5speed cable shifter/cables/tranny shaft end piece (slips on the shift rod and cables attach to it). The end piece is the same size as the 915 shift rod.

Anybody here have any thoughts on this, anybody try it?

If you already have the 914 sideshifter, that would be your easiest and cheapest choice. However, you will need a new flywheel and notched bellhousing to run the electronics.

If you already have the 915, I would highly recommend hunkering down and springing for the WEVO kit. You won't have to replace the flywheel, pressure plate, etc., so all of your clutch setup is taken care of, and the converted 915 is certainly geared for the torque of the engine. If you need the name of a shop in Illinois that can do that for you, I would try Perfect Power in Buffalo Grove, IL, or if you don't mind a slightly longer drive, Brad Mayeur in Peoria, IL would be good to handle the 915 trans conversion.

The Boxter cable shifter is very difficult to adapt to a 915 trans. The work to get the geometry correct for the cable push and pull throw lengths are not even remotely close for each box.

I went with this system which is sold by PMS. I am raising the shift tower higher to obtain better ergonomics (like a 935) and could not get a straight plane for the shift rods to go with a WEVO which I would have spent the money if it worked.
The reason I liked this system is it can be located forward, back, tilted, higher than the factory shifter location.

I found out about this system from a friend who has one installed in a sand rail with a 3.2 and 930 trans that I drove out in the desert for a day. Everything was covered up in aluminum bodywork so I did not know it was a cable setup. Once I got out of the drivers seat and looked underneath I was impressed at how well it worked. A 930 box is a notchy shifting unit anyway and I have driven them in a 911 Turbo. The operation of the cable shifter was so impressive I abandoned going with the WEVO setup.
