HPI 6SPEED CROSS MISSION for S15

■The ideal gear ratio allows you to fully enjoy circuit racing and drifting.

The ratio of 1st to 2nd gear was brought closer to 3rd gear, and the ratio of 6th gear was brought closer to 5th gear. Also,

Competition-specific gear is designed with an emphasis on strength and ease of manufacture, and the gear

The bite ratio, which is important for quietness, is low, and the tooth surface is roughly polished, resulting in a "whirring" sound.

The sound is very strong and not suitable for everyday use. Please consider this point when using it for everyday purposes.

We have selected specifications that can withstand such conditions and set the gear ratio accordingly.

HPI enhances the performance of Nismo transmissions through its own internal processing.

They succeeded in raising it even further, and its potential is supported by many drivers.

I'm continuing.

■The increased gear diameter due to the gear ratio change has improved strength.

Furthermore, by changing the module (gear specifications) without changing the gear ratio, the counter...

The strength is increased by reducing the number of teeth on each main gear and making each tooth larger.

By reducing the twist angle of the tooth, the counteracting force from the impact torque input was achieved.

- Reduces thrust impact force in the forward direction of the axis, and the end of the counter reverse gear

We have implemented measures to prevent surface damage.

■While retaining the best features of the standard 'FS6R92A', the strength and gear ratio have been optimized.

This means that dog transmissions and old-fashioned synchronizer mechanisms, which were designed solely for competition,

It offers unparalleled ease of use compared to other systems.

■The S15's speedometer receives its signal from the ABS sensor,

The transmission does not have a speed drive gear. Therefore, S13, S14

Therefore, it was impossible to display the speedometer. Taking this into consideration,

The speedometer drive gear is installed, as well as the parts necessary for the replacement.

We have addressed the issue. (Nismo product / Nissan genuine part)
