Honda
JDM Short Gearset |
 Japanese
and European 5-speed NSX are equipped with a gearset that offers tighter
2-4 gear ratios. The US gearset results in shift
points in the lower gears that places the resulting engine speed below
the optimal power point. The JDM short gears allow better acceleration
especially noticeable in the shift between 1st and 2nd as the engine
does not fall out of the useable powerband. The JDM Short Gearset includes all parts to
retrofit your US-spec gearbox. This modification results in faster
acceleration times. Excellent in combination with the NSX-R 4.23 or
Comptech 4.55 final drive gears.
The kits include the mainshaft and gears for the counter and mainshaft.
For high mileage NSX, we recommend replacing the common gears found in
all NSX transmissions. |

We offer as an option the "common gears"
found in the US and Japanese 5-spd transmissions. These three gears
include the countershaft 1st gear, mainshaft 5th gear, and countershaft
5th gear. These gears do not need to be replaced in transmission
rebuilds unless there is existing damage or there is wear from mileage
(we usually recommend replacing these if the transmission has more than
150k miles. |
