That mendola gear box would cost more that a porsche 6-speed.:silly:

The VW TI gearbox modfied to a 5 speed is much easier to fit into a beetle. With the Porsche you'll need to do alot with the clutch arrangement as well as the mounting, especially a 915. The 915 gearbox is also about 50 pounds heavier than a TI 5 speed.

Thanks for the information guys.

Now I will be able to make a more informed decision about my transmission.:D

If it were mine I'd set it up with the Beg it and gearing that is friendly with the engines powerband and the tire sizes used on the car....

Very few Porsche trannys have optimum gearing for a TI or TIV engine transplant right out of the box. A gear swap ain't cheap.

i know this is just of topic
i have been going thriugh this process as well.in the end i have gone for a typ 1 irs 4 speed simply for cost and relieabilty.
porsche 901 not strong enough
porsche 915 strong enough but gearing not
typ 1 irs berg 5 speed HOW MUCH ££££
typ 1 irs rebuilt with close gears:) :)
just my views and the way iam going good luck which ever way you go
cheers rob

I have looked at the options and I think I'm going to stick with my built 4 speed for now and probably get the berg 5 speed conversion later on when the funding is available.;)

Thanks for all the information guys.:D
