[QUOTE="Haveacamper, post: 614854, member: 2051"] Just wondered if any if those with performance engines around the in 180+BHP have upgraded their gearbox ratios to improve 1st and 2nd. My 091 box 1st gear is pretty much non existent when accelerating off the line. I've had my 3rd and 4th changed but I'm now thinking that 1st and 2nd would be better off closer to the Porsche standard box ratios. 1st and 2nd are ok if pootling around but as I've changed third to span the gap to my longer 4th gear I now have a bit of a gap from 2nd to third. Not sure I fancy the work or cost involved going 5speed especially as I've sunk x amount im to rebuilding the 091 with possibly less than ideal ratios. I appreciate that 1st and 2nd will mean a new main shaft and islets rather than just gearsets [/QUOTE]
