Hello,
I'm in the process of building a long travel dune buggy right now and want to use a Porsche gearbox. It looks like the 930 will be the best bet for the application and I was hoping you guys could help me out with the differences between the various trannies.
From what I remember the 930s were available from '79-86 and there were numerous engine combos that sat behind them. Are there also differences inside the gearbox, for instance, did the turbo models have a stronger ring/pinion and gear stacks than the non turbos or just a stronger PP/clutch?
Trans will be mated to a V8 with a Kennedy adapter (more than likey a Northstar or small block aluminum Ford, not sure yet).
Typical ring and pinion ratios are 4.11 and 4.86 for sand use. I've read there are a lot of gearing options available so I'm going to assume a 4.11 is possible to obtain (or something close). What are the ratios for 1st-4th?
If you have any info you feel would be helpful please let me know as I know nothing about these transaxles
