JB10 5 Speed Gearbox.

[Nick k]

Anybody know whether a JB10 gearbox is worthy as a replacement on a GTT. It was taken from a M reg 1400cc campus thing!! Cheers.

that'll be a JB1, and it's unlikely to be much cop

what are the 3 numbers after JB1?

hmm not sure.. i would of thort it would blow it to bits 2bh..

I think it'll be very similar to the shorter JB5's you find in the other NA's. I blew one to pieces. casing is shorter which to me indicates that the gears in there are not as broad as the JB3, maybe.

JB0, 2 and 4 are 4 speed. JB1, 3 and 5 are 5 speed
