Superior RB 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.

  • BMW 8HP90/95 (N73/74 engine)

Notes

  • Installation must be done by professionals preferably with transmission experience

  • The kit is only compatible with the Gen 1 flat style converters for BMW and Dodge
    (high tensile bolts for both variations included

  • Toyota JZ
    Pilot for Dodge converters will need to be modified according to instructions.
    (BMW converters are a direct fit)

  • Nissan RB
    Pilot for Dodge And BMW converters will need to be modified acc to instructions.

  • 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.  

  • 8HP70/75 option is delivered with the HPR Superior Cast Bellhousing

Toughest dang balls I ever played with
Color: D) 4-Pack 3" Balls (Yellow), Color: D) 4-Pack 3" Balls (Yellow)
These things are amazing. We have a ball obsessed Husky mix and he has destroyed Kongs, Chuck Its, and a whole lot of other ball shaped objects. These things? We bought the 4 pack because we bought 4 Chuck Its and they lasted a year, all 4 of them only a year, before they were destroyed. A year after buying these? We only bought more because he lost 3 of them. I think we did find one under the dresser after buying this pack... But the others? They either ended up thrown over the fence into the woods or lost in the holes in the yard the monster digs up. Other than a few pockmarks from his teeth and maybe some mud, they may as well be brand new even after a year or two. Probably the most chew resistant thing we've ever bought him. They're really solid rubber and since he hasn't managed to bite into them to take out a chunk, they're safe as hell. Being as big as they are, I don't worry he's gonna choke unattended on them like the usual size of ball. About the only concern is forcing breaks so he can have breathing moments when he manages to talk us into fetch outside. It fits in the larger Chuck It thrower too, so we haven't lost any value from having those torn up.

Sturdy bouncy fun!
Color: D) 4-Pack 3" Balls (Yellow), Color: D) 4-Pack 3" Balls (Yellow)
Great product. My big 70lb Sheppard puppy loves it, hasn’t stopped playing with it since it arrived. She throws it about and chases it, had a good chew on it and even put it in her favorite toys bin. Sturdy, firm and very bouncy. And there are 3 more in the bag for an awesome price. Bright color will make it easy to find and holes thru it will prevent choking and I can string it on a line for training play.

Dogs love these
Color: C) 2-Pack 2.5" Balls (Yellow)
Great quality balls for tough chewers. I love them, but wish the orange ones were available more...I've been checking cuz they are easier to find in the yard than the green that blends in. Our dogs love them and I like the weight for throwing.

The perfect toy for dogs!
Style: The Duo
This is perfect when you have 2 dogs who love to play Fetch! They no longer have to chase after the same ball! The balls that come with it are very sturdy, and the launcher sends both balls far enough away so that both dogs get plenty of exercise. It’s definitely worth the price!

PERFECT RETRIEVING TOY
Style: EcoFetch
You can barely whip it and it sails far and fast. This is the perfect retrieving toy for my GSP. She's used to average and we now have a small yard, so the dog park is where she gets to run hard and fast. You can also throw tennis balls with it, which is a plus for when her sister steals her ball. 5 star fun!
