Make sure to check out the video in the description for more info about transmssion you need to source for the kit.
8HP90/95 kit is based on the BMW N74 engine. Note that this conversion will require more chassis modifications, and are aimed at the serious users aiming for 1200+ Nm torque from a bone stock transmission.
Rear planetary gear:
The rear planetary gear needs to be removed from the transmission and be sent in to us for modification. We reccommend using a transmission specialist for the work.
Remove the clutch pack and teflon rings on the output shaft, and make sure there is no oil residue. (do not degrease it due to potential rust problems)
Make sure you pack it well. (Max box size is 40x40x30cm/10kg)
You will recieve a modified planetary gear with the correct splines to suit your Nissan GTR transfer (exchange basis).
The modification is done in house at HPR.
Turnaround time can be up to 3 weeks if not in stock.
NOTES:
- R34 GTR transfercase will not work with this kit
- Front propshaft needs to be extended
- Rear propshaft needs to be shortened for R32 and R33 chassis
- Minor chassis clearancing needed for 70/75 versions
- Tunnel clearancing for 95X version is yet to be confirmed
