Hang on, I thought Van Adeker's (spelling??) kit was more like $1000.
For that price, I'd do the 5 speed in a second. It's a Toyota, which
mean it will last forever. And it's rated for around 300hp, so you
sure as heck can't break it.
I've had my o/d tranny rebuilt twice on my 6, and each time, the 3rd
gear syncro has gone south. With all the poor quality reproduction
parts being manufactured for rebuilding Triumph gearboxes, I think it's
going to be hard to rebuild the tranny and make it last. If I had
bought the Toyota tranny when my gearbox fell apart the first time, I'd
be ahead of the game by now.
As an added bonus, putting in a Toyota gearbox means you don't have to
worry about the infamous Triumph clutch problems.
When I get the cash, the Toyota box is going in my car!
