jspec racing hehehe
anyways..
I have a R34 GTT Gearbox, picked it up for $1500, with 17,000kms on it, i thrash the absolute crap out of my car, and this box loves it (200rwkw)
if you can afford $3,000 for a new one, get a gearset for your s15 box, would be the same price or around that and less f**king around.
just an idea
