We have a (Pre-Owned) performance gearbox setup that came out of a Nissan Skyline R33 GTR . This is a fantastic opportunity for anyone looking to enhance their vehicle's performance!

What’s Included:

- OS-Giken Close Gear Ratio Set: Offers improved acceleration and performance.

- Factory R33 Transfer Case: Complete with upgraded large spline.

- Extreme Twin Plate Ceramic Clutch. Only 1.2 km of use—practically brand new!

-Strengthen Input Shaft

-Two Shifters:

- C’s Short Shifter (for precise shifting)

- Brand New Nismo Billet Solid Shifter (perfect for a solid, direct feel)

***OS Giken ratios: 2.695, 1.703, 1.236, 1.000, 0.826

***Standard ratios: 3.214, 1.925, 1.302, 1.000, 0.752

Condition: Most components are in excellent condition with minimal wear.

The OS Giken gear component is designed and created from high-quality forged materials, and then undergoes hard shot peening, resulting in increased strength and durability. Furthermore, the gears are helical-cut, rather than straight-cut, to maintain a quiet and smooth operation, accomplishing full comfort for street driving as well as reliability for racing.

OS Giken close-ratio gearset for FS5W30A gearbox in BNR32 and BCNR33 GT-R, ECR33 and ER34 Skyline turbo and Z32 300ZX twin turbo, 5-gear kit including input shaft.

OS Giken close-ratio gearsets offer greatly increased gear strength, along with closer gear ratios to suit racing applications. The retention of normal synchromesh parts and a helical gear design means the gears are still almost as quiet as a standard gearset, so this is an excellent upgrade for street-driven vehicles too.

The gears are rated at 1200ps, so they are suitable for most modified RB engines. The limiting factor is the Nissan synchros. While the latest version of the synchros is used, they may still fail if shifting too fast at over 9000rpm. For this reason, extreme drag car applications should look at the OS-88 sequential gearbox. That said, this gear set has been used successfully in a number of 9-second GT-Rs.
