right then.while at 1st the 6 speed from a punto 55 seems a great upgrade there are a few issues.

the main stumbleing block is actually finding one as these are very hard to come by 2nd hand.

the next thing is the 6 speed 'box is slightly longer than the 5 speed box so you will get some rubbing on the end of the 'box at full lock.

its not a straight fit either.you will need to transfer over the cinq selector mechanism.



what you need to be aware is the difference in ratios.the 6th gear is actually lower than a cinqs fifth gear so not really any god for top speeds nor motorway cruising.
a cinq on sporting alloys would do 93mph at 6000 revs in 6th
also a cinq speedo drive would give you a higher reading than actual speed.
novitec used to do taller 5th gear kits but these have been discontinued.

however the closer gears in a 6 speed will allow you to keep the car in the power band more,right up the gears.

now unfortunatly,later seis use a difference driveshaft set up so i cannot confirm whether or not they are a straight fit or not

heres a comparison of ratios on 3 punto models

55/60/75* 55 6sp Sporting 6sp
1st 3.909 3.545 3.909
2nd 2.157 2.157 2.158
3rd 1.480 1.480 1.480
4th 1.121 1.121 1.121
5th 0.902 0.902 0.921
6th N/A 0.744 0.766
F/D 3.563/ 4.923 4.071
3.733

* Final drive is different depending on the wheels, the 13" models get a higher ratio FD to compensate for smaller rolling diameter

thanks to pete(fixitagaintommorow) and stonenewt for the info

Custard, just to add. You can pop the inner driveshaft cups out of the cento box, and put them into the 6 speed. That solves any driveshaft issues
