as above realy. you cant buy them any more. it is all made by jkd even the casing! may be worth a bid. and 4th gear is 1:1 and fifth is an over drive.

I used to run one happily with 155 BHP & 119 fLbs Torque(aspirated not turbo) But it was straight cut. I was told Helical JKD 5 speed wern't good over 100 BHP, not sure how accurate that was, but remember it maybe difficult to get spares as I'm sure JKD are no more !:(

i assume its the box from the cooper sport 5

if so they had trouble coping with the 65bhp of the cooper s works (coopers claimed 90bhp but didnt get any were near 90bhp)

i spoke to a relatively tame driver and he had the box changed 3 times under warranty.

It is not so much power as torque that will kill it, my understanding was it is suitable for mild tune NA 1275's and nothing more.

Id agree with Tom I heard they were'nt up to more than 80/90bhp..
I know a lad putting one into a highly tuned N/A 1380 at the moment, I tried to talk him out of it but he's insistant on a 5speed... in my eyes an unnecessary expense.. one I think he may find out the hard way!!! *surprised*
