hello their people, my first post. my problem is my gearbox is knackered and im having trouble trying to find a s1 box. the mechanic who is going to fix it for me has sourced a s2 box. the guy who he got it from said the mounts are interchangable but he wasnt 100% sure, also some other mechanic said that it will fit. ive heard that it can be done and ive heard it cant be done. please, please can someone confirm it can or cant. thanks in advance.

 

AS far as I'm aware you can put a S1 box into an S2 but not the other way around

Why not have your original S1 box rebuilt? Bernie at CTS is the bollocks. Only gearbox I haven't actually managed to kill Not silly money either

You cannot directly fit a S2 box into a S1. The mounts are different. However, I believe the casing is the only difference that stops you fitting it. So you could swap all the bits into a S1 casing - if it was worth the hassle.

 

I have a series 1 box done approx 3k, fitted with an uprated mainshaft bearing & series 2 gear ratios.
price is £200 collected & I'm in Sheffield.
