So I'm test-fitting my engine and transmission in the car right now, and I'm having some problems. Perhaps someone can offer some advice.
Engine is a 2.7 liter, transmission is a 901 pull clutch, mount (for now) is a Patrick Motorsport piece. Issue #1: supposedly the clutch cable to use is a 72-74 911 unit. The sheath is a little short, though, and making a bracket isn't necessarily easy because part of the crankcase prevents me from having a straight shot. I have an idea of how to do this, but I'm wondering if anyone's done this before. Here's a pic: Attached image(s) |

This is what I can say for the 911 pull clutch transmission:
It was problematic in the 911 application because Porsche had to make a cable "push" the throwout fork. It had to go through all sorts of different gyrations to make the cable sheath effectively do the work. In a 914, it's just the thing to eliminate the cable pulley. You have the same strength issues as other 901 boxes, but there's also additional strain on the ball pivot. A heavy clutch like those intended for 915 boxes can break or tear that pivot right out. The best way to handle a stronger motor like a 3.2 is to upgrade to a stronger gearbox, like a 915. I'm sorry to have suggested otherwise. I decided to go pull clutch more as an experiment than anything. If I had just stayed with a push clutch, everything would have been done by now, but no, I just HAD to challenge the pulley. Now it laughs at me as I try to figure out how I want to make a bracket for the cable. (IMG:style_emoticons/default/gunner.gif) (IMG:style_emoticons/default/ar15.gif) |
