Superior JZ bellhousing kit: Installation guidelines

Introducing the billet 8HP bellhousing for your Toyota JZ and Nissan RB engine!

The crown jewel of the new Superior kit is undoubtedly the billet bellhousing, 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. Meticulously curated components ensure a premium feel and an unmatched driving experience for enthusiasts.

A Superior solution for any 8HP conversion 

This solution offers a superior alternative to traditional adapter plates for any 8HP conversion. It eliminates the need to cut clearance for the starter in the OEM bellhousing while providing a slimmer design for better transmission tunnel clearance. Being up to 40mm shorter than adapter-based designs further enhances fitment. Unlike conventional solutions, there are no compromises with colliding bolts—every engine and oil pan bolt is utilized. Additionally, its lightweight construction removes the need for an adapter entirely. The billet steel one-piece flexplate, featuring an integrated starter ring gear, ensures durability and reliability.

The kit is now available as a parts kit, and can also be added to all of our vehicle kits as well.

• Dodge 8HP90 OEM casing has a symmetrically different appearance compared to the BMW 8HP90 casing. Therefore some gaps between OEM housing and billet bellhousing will appear. Some clearancing is required between bellhousing and casing. This has no effect on the function of the product.
