it doesnt have to be a Gene Berg tranny, unless you are considering a 5
speed tranny.

If you are going 4 speed, then any reputable shop can build you a race
4 speed with aftermarket ring & pinion and aftermarket gears. Also a gusseted
case would be a good idea, as well as billet side covers and a super diff.

You are looking at around $1500 minimum for a tranny like that, possibly up
to $2000.

If you wanted to save a little money (but with more risk of breaking stuff)
you could go with a Super beetle R&P and a stock 1st & 2nd gear and this
would save you about $500.

A Berg 5 speed will cost you $3000 to $3500 at least.
