hey,
i have a b16a2 with a y21 gearbox and i've been wanting to buy a itr 4.7 final drive, what do i need to change from my 4.4 Fd to an itr 4.7?

TIA

 

you need a gsr or type r differential and the complete 4.7 kit. B16 and LS differential have different bolt pattern for the ring gear, and will not work, gsr and type r are the same pattern and will work with the kit. I recommend http://www.hmotorsonline.com they have the final drive for $350.

 

ok,
so i just need to buy the kit from hmotors online?

I have bought tons of parts and motors from them, great price, customer service and reputation. Highly recommended

This would be a good time to get a typr R LSD.
