For more enjoyable sports and drift driving, first and second gear ratios have been brought closer to third gear, with the sixth gear ratio closer to fifth gear. With most of the competition oriented gears in the market, strength and ease of production are emphasized in the design process, and a lower gear engagement ratio and rougher tooth surface grinding may cause noisy whizzing sounds for daily use. Nismo carefully considered these factors and developed gear ratio specifications that allow for daily use as well.

By changing the gear ratio and increasing the gear diameter, strength has been improved. Where the gear ratio has not been changed, changing the module by reducing the number of both counter and main gear teeth and increasing the size of individual gear teeth also increases gear strength. By reducing the torsion angle, the thrust power shock to the front of the counter-shaft caused by the input of shock torque is reduced, helping to reduce potential damage to the end face of the counter-reverse gear.

The Nismo Reinforced Cross Transmission draws on the strengths of the standard FS6R92A, and through reinforcement and optimized gear ratio provides a level of operation incomparable with competition only dog transmissions or synchro transmissions of the past.

Use on S15 (SR20DE), S14, S13 Because the S15 speedometer obtains its signal from the ABS sensor, there is no speed drive gear on the transmission. Because of this, no speedometer indications will be available on the S13 and S14. When installing the NISMO Reinforced Cross Transmission in the S13 or S14, a speedometer drive gear has been prepared which must be attached.
