    Default 205 S2 Mi16 Gearbox??

    I'm sure this has been talked about a few times before, but i'm after any advise/help on what people suggest on the ideal gearbox for my 205. Running XU10j4 Mi16 with matching box and quaife LSD. Peter T stage 2 inlet and stage 1 cam. Power kicks in at 4500/5000rpm, but find it a little sluggish down low. Car is a semi daily driver and does go on the Fwy a little bit, so don't want it revving it tits off at 100kph. I intend on the odd track day in the near future. Any advice would be much appreciated.

    GTi ratios with a 4.06 cwp.

    Not 4.06. What happened to the original gearbox from the car? You could use that with the Mi16 cwp.

    Just use the Mi16/S16 box. Its got shorter first and second and nicer higher gears. Perfect for a 16v 205. Theres a slight jump 2-3 but not worth writing home about.

    Otherwise just reduce your cam a little.

    Cameron is sort of correct. Your current Mi16 box, with its 4.43 cwp, has the same 1st and 2nd as a GTi box. Thus you'd see no difference there. A gain in acceleration comes from the shorter 3rd and 4th, which would keep it on the boil between gear changes. It's a case of you can't have your cake and eat it too. Big cams = lower and closer gears.

    As Pete says. Big cams = short gears. Something Rich W may be considering also! If you have the time and money a custom box is the way to go. Until thwn I would try the box you have lying around. Otherwise use your stage 1 cam on the inlet (that work pete?) and standard exhaust cam

    Thanks Pete and Cam. Unfortunately the old 1.9 gearbox is long gone. Doesn't sound like a huge gain to change ratios for the effort and money, for what the car is being used for. If a box comes up for sale at the right price though, it will be worth looking in to.

    Hi Griffo,

    PM or Email to me your phone number, but don't get your expectations up yet.

    There is a possibility I may be able to help with a gearbox.
