Gearbox


A popular modification to the standard S9B gearbox is simply to replace it with an S80 gearbox from a post 98 Integra Type R to gain better acceleration.  This is mainly due to the renouned fact that 2nd gear, in the S9B gearbox, is too long for any decent acceleration.  It is rumoured that the standard gearbox was developed for economy and the motorway, thus keeping the revs down.

Gearbox Ratios:
1st Gear
2nd Gear
3rd Gear
4th Gear
5th Gear
Final Drive

S9B
3.230
1.900
1.360
1.034
0.848
4.266

S80
3.230
2.105
1.458
1.034
0.787
4.785

As you can see, the S80 gearbox ratios are shorter in 2nd and 3rd whilst longer in 5th, also the final drive is different too.


This chart compares the speeds obtained from the two gearboxes at 8000 rpm and running on standard 195/55/15 wheels and tyres.
