Poll: gears for a /6 Options

[PanelBilly]

Seems like its money we'll spent to change the gears and take full advantage to all the power a bigger engine produces, but what did you do? And if you didn't, do you regret it or are you happy starting in second?

Agree with Rich. You can support the motor and yank the tranny fairly easily but, if you know your intended use you should be able to put something together that works for your style and your engine.

I'm not in favor of a taller first for one reason, the shaft isn't really strong enough for that type of driving with that type of torque. I've had mine spin the shaft right there. Life is not fun with first rattling around in your tranny nose cone.

I would concentrate on 2nd-4th to take advantage of your power and torque band and plan 5th for best mileage and economy. The only problem with having a tall 5th in an air cooled motor is, they can depend on the RPMs and the fan to keep them cool. This is why the 914-6 received a Za gear for 5th. If you have a front cooler, which I think you do, you can worry less about that. I'm not sure what a Carrera gear set would be but, there's a car of similar power that has a front cooler and, in stock form, would potentially deliver the best cruising fuel economy in 5th. You're also lighter so you may be able to go slightly taller and get away with it.

Here's how the theory played out in my tranny. I'm a 2.5 SS so it will be quite a bit different. I went with a stock first and second then, M, S and instead of the familiar "X" I used the stock 6's Za. I wanted a gear tall enough for cruising but short enough to play well with the S if I had to downshift on a long grade.

You have torque and tons of it. If I recall from building your suspension, you want a street driver that you can have fun in the twisties with.
