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

There's a fellow (Derick) that has a 904 recreation he's working on (P904@shaw.ca). He has a 930 box with the Vellios conversion for sale for $8500, a good price in my opinion considering the steps you have to go through.

Dr. 914s comments on the 915 conversion seem quite right on. I used the Vellios conversion on mine, and had similar experiences. The 915 does shift nicely now, but I used a 915 shift tower, custom made linkage from metric sized metal tubing, and a nicely converted transmission. All the items can be taken care of pretty easily, and even the clutch cable works OK. I used the 90 degree adapter from Patrick to change the orientation of the pulley to horizontal.

A billet side plate with a mount for the electronic speedo sendor would be a nice part, but I used the standard one with a machined area between two stiffening ribs to mount the sender.

The Vellios tailpiece seems to take care of the spacing, as my transmission fit without any clearance issues. I also used the WEVO transmission mounts to help the shifting, and a Rich Johnson front mount.

I used an early (1975) 915 transmission, so I had the course splined output shafts already. I simply had to swap them for the 914 ones, and the axles were taken care of. I have been slowly assembling the necessary parts to go back to the larger CV jointed axles, but that's for a future project.

Another minor point is that you have to come up with some way of switching the backup lights as the 915 doesn't have the required boss on the side. I mounted a microswitch to the transmission, and an activating lever on the shift rod itself.
