Considering another tranny project, 70-71 901 in a 914 Options

[Red-Beard]

The late 901 and the 915 use the same style clutch and it's a 225 clutch, so it's more capable, HP wise.

Internally, the 70-71 901 is the same as the early 914 901. Doing a sideshift conversion on one of these would be relatively easy.

What is the clutch cable setup for the 915 in a 914?

Using the70-71 911 trans is the way to go. All you have to do is swap in the side shift parts from a 914 trans. That is what I am doing. I already have the transmission. If you use a 914 trans, you have to move the clutch pivot point 14 mm and find the clutch fork from the 70-71 911.

The pivot can be bought from Pelican, or Mid America, or any of the other P-car parts suppliers out there. The insert will have to me made by a machinist,but considering that it's just a piece of stee bar stock turned and tapped, it should be farily cheap. The problem is that unless you use a 2.2 pressure plate, the stress is too much for the threads in the magnesium case of the 901 trans. Putting a steel insert with a large flange on the backside spreads out the load, and provides steel threads for the pivot.

The Flywheel can come from any 911 that uses a pull type clutch, as can the pressure plate. It is a flat flywheel. The 914/6 flywheel is a cup type, and can't be used with this setup.
