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?

I have been preaching about this for a while. The clutch is a bastard setup, not hard just a mismash of parts.

You have to use a throwout bearing and clutch disk from a 70-71 911. The disk has the correct splines for a 901 but it is 225 mm in diameter. The throwout bearing is a special piece to match the clutch fork. The rest of the clutch pieces can come from any pull type clutch setup.

You will also need to machine the clutch pivot mount hole in the case. You have to add a steel T shaped insert, pressed in from the INSIDE. This will keep the threads from pulling out of the case when you use a stronger 911 pressure plate. Then you have to get an after market clutch pivot. The stock ones break.

The cable is from a 75 911, and it will bolt in. Use the 914 clutch trunion, and you are set.
