I think the RB is about 3500rpm in 5th, which will be a similar gear to the RAs 4th.


See if you can get any part numbers (doubt it tho) from inside the box if you open it up and I'll see if I can find anything.

well mines is sitting bang on 4000 rpm at 60, revving its guts out. it feels familiar to the RB. i hope ive not bought another one - i wanted something a bit more practical :cry: :cry: :cry:

3rd gear 1.271 /1.653
4th gear 0.954 /1.272
5th speed 0.740 /0.911

I can't confirm which one it is. I'd hazard a guess at the RB ratios. There's also a Nismo gearset which is closer still I believe.

RB ratio..
possible high chance
but the material look very different from RA as well.
