A Superior solution for your 8HP Conversion

Designed for Toyota 1JZ / 2JZ, the kit allows installation of BMW Dodge/BMW 8HP90, 8HP95 automatic transmissions. By replacing the original transmission bellhousing rather than using a conventional adapter plate, the HPR Superior Bellhousing creates a shorter, more compact drivetrain package with improved transmission tunnel clearance, without the need to modify the factory bellhousing for starter clearance. The Superior Solution for your 8HP swap

Kit contains:

HPR Billet Bellhousing Adapter for Toyota JZ engine
- Installed ZF Roller Bearing
- Installed ZF Lock Ring
- Installed Front cover oil seal

Toyota 1JZ, Toyota 2JZ

Transmission fitment:

BMW 8HP90 Gen 1
BMW 8HP95 Gen 2

Dodge 8HP95

Gen 2 transmissions can also be used with the kit, but it requires the usage of a Gen 1 style converter to suit the build length of the billet bellhousing.

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.

Installation Support:

The general installation procedure and practical steps are the same as for the 8HP70/75/76.

However, the bellhousing cutting dimensions and torque specifications are specific to the 8HP90. Please refer to the dedicated 8HP90 Installation Guideline for the correct cut details, measurements and torque specs.

This video shows the practical procedure on how to remove and install bellhousing. This is shown on a 8HP70 transmission.
