A properly geared transmission, whether a 5 or 6 speed is a huge improvement in performance.

this is what i am thinking, if i ever rebuild the box, or should i say when not if... i'd want an lsd, and look at the ratio's, but what?

top of 130? it must be like adding a fair dollop of horsepower...

I have often used a 5th gear ratio equavlient to the current 4th and replaced 2,3,4 gears properly matched. That makes a very nice trans with a warmed over 964 engine.

Default Tip to 6 speed

Iím considering buying a C2 thatís Automatical Triptronic itís a great price and has a lot of stuff that I would do if I got 1 stock. Only major drawback is Triptronic
Someone mentioned $9,000 for 6 speed is that the same starting from a Automatic? If not how much more?
Anything else I should consider?
Yes I realize itíll hurt resale but itís a keeper so whatever.

Iím wanting to convert a factory 91 964 Triptronic to Euro spec 6speec with LSD. I have heard that Iím looking at around $15,000 does this sound right?
What else is required to go from Auto to standard?

Lots of stuff... top-of-the-waves list is: driveshafts, starter, clutch kit and flywheel (obviously), pedal box (with floorboard, carpet), hydraulic (master, slave, hard and soft lines), transmission mounting components, shifter (linkages, lever, boots, bushings and welded box(though I skipped this)), electronics (speed sensor and bracket(?) , jumpers, reverse light wiring), and throttle cable. Probably best if you find a wreck/part-out for most of these.

You're better off selling your car and buying a manual.
I swapped my 5 speed for a custom geared 6 speed. Needless to say it was seriously expensive, and I'm sure a year later it's only
More money. Those transmissions are hard to find

Search my username for my build thread. I think it was around 30k ( trans, custom gears, gt lsd)

Honestly it changed the car. Feels so much quicker with the right ratios keeping it in the power band. It's like adding 50hp. Doesn't make sense from a financial standpoint, but that's easily forgotten once you drive it.
