I've already done a good bit of searching and have yet to find what I'm looking for, so here goes-
Is there a good, comprehensive thread which explores/discusses the tradeoffs (functional performance, prices, availability) of the various options for converting a 915 tranny for adaptation to a 914-6 conversion project. Thanks. |

Porsche went to the 915 with the release of the 2.4L engine for a reason. I have a 901 attached to a 2.4S motor, and I have broken it three times now. Big tires, torque biasing diff, and 944 turbo CVs means the weak spot is now the trans. Unless you baby it, a 901 wont last behind a high horsepower motor. And what is the fun of having a 914 you have to baby????
I don't like the 915. But I was considering it before I decided to upgrade to the 4.0 Monster motor. Lots of friends in PCA tell me the 915 won't handle a really hopped up 3.2 used for racing. I have seen lots of 915s eaten up at the track. Should not be as bad in a 914 because it is lighter. |
