Found site thanks, my question is this a 98 Spec R gearing are 4:785 final drive vs 91 SiR 4:266 0 final drive. Also, really don't see the close similarity as people speak of the B16A1 gearing to the Type R. My, question is let's compare a B16A1 final drive 4:266 vs 98 Type R final drive 4:40. Does that mean at say 80 mph with B16 rpm is at 4K oppose to Type R at same speed rpm is higher or lower. That's one main thing not too familiar with & I've had plenty of cars.
