Superior 8HP to GTR kit

Upgrade your Skyline GTR with the ultimate drivetrain package: a complete GTR chassis kit, paired with an HPR-prepped 8HP transmission of your choice. With precision machining and essential external components—like the billet bellhousing—pre-installed, installation is straightforward: simply bolt on your transfer case and install the transmission as a single unit.

At the heart of the kit is HPR’s billet bellhousing and flexplate—the crown jewel of the Superior Kit—ingeniously merging the 8HP centerplate into a singular unit.
Developed in-house at HPR, utilizing cutting-edge metrology-grade 3D scanners and Geomagic Design X software, the Superior Kit sets a new standard in transmission upgrades. The components ensure a premium feel and an unmatched driving experience for Skyline GTR enthusiasts.

 

Advantages of the Superior Kit for your Skyline GTR:

• No chassis modifications required for all Skyline GTR models.
• No cutting needed in the bellhousing to fit starter or front propshaft.
• Matches the built length of the 6-speed Getrag found in the R34 GTR.
• No custom front propshaft necessary (spacer kit supplied for R32/33 users; R34 direct fit).
• Includes a billet steel flexplate for added durability.
