My gearbox doesn't have many miles left and I'm looking to swap it to a 6 speed. I will be also building an engine soon to be near 400bhp.

So question for the cleaver people, my gearbox code is TY754VN2AA and i assume my diff will be 3.545.
What 6 speed box code should I be looking out for so I do not have to swap the diff, drive shafts and hubs??

cheers for your help

 

Ty856wn2ca, 3ca, 4ca are uk non dccd 6speed , and correct for uk wrx dif ratio

 

Thats great, thanks alot
