So my plan for this car is to utilise the 915 gearbox that I already have. I bought the box some 20 odd years ago to put in my Karmann Ghia along with the big Type 4 engine that's also getting fitted, but a change in direction has meant that it's been sitting around collecting dust waiting for an appropriate project to put it in.
The one part of the oval project that has given me the the most challenges is the 915 gearbox conversion. Most people that opt to go down the Porsche 5 speed route use the much easier to fit 901 gearbox from the Porsche 914 / 912. Whilst not as strong as the later 915 box it shares the VW mountings, uses a cable pull style clutch and is much simpler to install. I opted to go with the 915 as the 901 was not suitable for the power of the big Type 4 that I had planned to hook up to it, plus I did not like the dogleg shift pattern of the 901.
If you read my last post - 'Hydraulic clutch slave' which was about fitting a hydraulic clutch to a Porsche 915 gearbox you might have thought that it was a good solution to an otherwise difficult issue to solve. Well that is what I thought until I tried to fit everything together. What I actually found was that the slave cylinder that I used was too long and meant that it fouled on the clutch assembly when the engine was installed in the gearbox. With limited time to buy and fit another shorter unit I decided to look at converting the old pull style 915 clutch release to a traditional push style.
I've decided that running two lots of forums on the same thing is probably a bit of a waste of my time so I intend to close down the forums on my personal site (www.t-34.co.uk). There's probably not much of value (not in the public forums at any rate) but there is a pretty good thread on the 915 gearbox conversion that I will try to bring across. To do this i will probably have to migrate all of the members across as well.

Will keep you posted
