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.



IN THE KIT

  • BILLET 4340 FLEXPLATE WITH HARDWARE

  • BMW 8HP90/95 (N73/74 engine)

  • Dodge 8HP90 Hellcat 


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.

Classic and functional
Color: Stainless Mesh/ Blue Dial
High quality and affordable watch. Love the mesh band. It’s a classic, functional everyday look. Easy to adjust, and never runs out of power. Perfect for men who have smaller wrists. Bought for my husbands birthday, and he loves it.

Everything as expected
Color: Stainless Mesh/ Blue Dial
It's a nice watch added to the collection, looks really good on hand, the metallic mesh band is very elegant and also customizable, so it will fit perfectly on your hand. It seems that it had a bit of charge out of the box, but I'll leave it under a direct (under 20cm distance) LED desk lamp to recharge overnight, I'll also leave them under sunlight around the windows whenever possible (at least for the first week or so), it's stated in the online manual that it will need ~45 hours to fully charge on a cloudy day under the sunlight. By the way, it would've been nice to have the manual in the box, but at least it's easy to find the (generic) manual in their website. The fluorescence of the hands and hour dots are really bright and mine had nice bluish color. Of the features, the chronograph works perfectly as expected, the manual also states to set the time 5 minutes ahead of the real time then slowly rewind back to the current time whenever setting the time, for the time keeping to be more accurate because of some gear movements inside. To be honest, it would be great to see Citizen use scratch resistant sapphire instead of some mineral as the face protective layer, as they do for other high-end models, the technology is not new and I think it wouldn't make it that much more expensive, I hope this one will be resistant enough🤞🏻 Overall, this is the first day I received the watch, I'm quite happy with my purchase, it's nice knowing you won't need to replace the battery anytime soon 😛

Great watch for the money
Color: Stainless Mesh/ Blue Dial
Looks great. I swapped out the band for a leather strap. Nice watch, well designed. My other eco drive has been going strong for 15 years or so without a hitch. So I have high expectations for this one.
