Based on the S15 6-speed transmission, this transmission is made with a
gear ratio for truly enjoyable high performance driving as well as increased
gear strength.

Ideal Gear Ratio
For more enjoyable performance and drift driving, the first and second
gear ratios have been brought closer to third gear and the sixth gear
ratio closer to fifth gear. Most of the competition gears in the market
emphasize strength and ease of production in the design process and
deliver a lower gear engagement ratio with rougher tooth surfaces that
can cause a noisy whizzing sound when used for everyday driving.
NISMO carefully considered these factors, and developed gear ratio
specifications that allow for normal, street driving as well.

Improved Gear Strength
Greater strength was gained by changing the gear ratio and
increasing the gear’s diameter. Where the gear ratio was not
changed, the module was fortified by reducing the number of both
counter and main gear teeth and increasing the size of the individual
gear teeth. The thrust power shock to the front of the counter-shaft caused by shock torque was diminished by reducing the torsion
angle. This also helps to avoid potential damage to the end surface
of the counter-reverse gear.

Superior Operational Feeling
The NISMO Reinforced Cross Transmission draws on the strengths
of the standard FS6R92A. Through reinforcement and optimization
of the gear ratio, we’ve reached a level of operation incomparably
better than competition-only dog transmissions or the synchro
transmissions of the past.

Use on S15 (SR20DE), S14, S13
Because the S15 speedometer obtains its signal from an ABS
sensor, there is no speed drive gear on the transmission. Because
of this, no speedometer indications are available on the S13 and
S14. When installing the NISMO Reinforced Cross Transmission in
the S13 or S14, a special speedometer drive gear is available
separately and must be attached (Car by car workup ).
