8HP70/75 and 8HP90/95 conversion kit for the Skyline GTR chassis


A complete bolt in transmission chassis kit for the R32, R33 and R34 GTR models. 

This kit retains the factory Nissan Attesa AWD system by the use of a transfer from an R32, R33, GTR, GTS-4 or Stagea transfercase. 

We also have plans on releasing a version of this kit with the Infinity Intelligent awd system. Please contact us for more info.

8HP70/75 kits will be a bolt in kit similar to our DCT kit. 
Thi kit is based on the use of a BMW 8HP70X transmission found in all N57 equipped awd cars from 2013-2017.  This kit will only require minor tunnel clearancing

Due to the complexity of this conversion, we reccomend most customers to purchase a complete 8HP to GTR package.


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. 


 Other things to note

  • 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
