Superior JZ Cast Bellhousing

Coming Soon: HPR Superior Toyota JZ Cast Bellhousing Kit – 8HP70/75 Size
A new, more accessible version of HPR’s game-changing Superior bellhousing system is coming soon for Toyota 1JZ and 2JZ engines.
 
Designed for 8HP70 and 8HP75-size transmissions, the new cast bellhousing replaces the original transmission bellhousing entirely rather than relying on a conventional adapter plate. This creates a shorter, cleaner drivetrain package with improved tunnel clearance and no need to cut the factory bellhousing for starter clearance.
 
The kit will retain the key advantages of HPR’s proven billet Superior system, including its billet 4340 steel flexplate with integrated starter ring gear and complete installation hardware.
