What would be the differences between the gearboxes for S1/S2/GTT?

Are they interchangeable, is one stronger than the other?

I noticed that rebuild kits for S1 and S2 differ..

 

Thanks

Yeah I've heard there might be some differences but havent been able to find any exact info. Looking to buy a second hand gearbox for my ecr33 and would prefer a s2 box due to cheaper and easier to find rebuild kits and if they have a bit better internals. Problem is, sellers dont usually know what series their box is

OK, thanks for that.

I would assume that with development of the car (S1/S2/GTT) design changed would have been made.

I read somewhere that the  late S2  (so 1998) gearboxes have larger synchros .. (no confirmed)

You should possibly ask about that in the forum .. I have no experience with these boxes, but it might be worth looking into buying a GTT gearbox (and the clutch conversion)

For R33 S2, the gearbox was changed 05/1998. The part number is 32010-21U60!
