Revision 2.0 Release, August 2022
We have continued to develop this kit for 18 months, and are finally ready to release a new revision of it.
Many changes have been done to ease installation and
improve the overall quality of the kit:
- New engine adapter design (no need for stock dust shield)
- New transfer adapter design
- No chassis modifications needed for R34GTR owners
- No propshafts needed for R34GTR owners
- Crossmember improvements
- Newly designed billet oil pump cover
- CNC machined cover for transfer
- Design changes done to mechatronics cover
- Dampened spline hub for flywheel
- Greatly improved output shaft design
(no park lock gear on VAR shaft)
R34GTR owners will especially benefit from the Rev 2.0 kit.
No chassis mods needed, and you can run with the stock propshafts with our new spacer kit for the front propshaft.
The 2.0 kit has the same price as the previous kit.
Description
The HPR Skyline GTR DCT kit retains the stock Attesa 4wd system in your Skyline, coupled up with a newer tech dual clutch transmission.
The 7 speed Getrag dual clutch transmission can be found in all BMW F-series M2/M3/M4 models (S55 engine)
The gears in the DCT are extremely ridgid, and have been known to take well over 1500 Nm in rwd applications. The stock clutches hold power levels up to 1000 Nm.
We have upgrades in the web-shop for customers seeking more.
This kit will get your Skyline GTR to the next level.
The tight ratios of the DCT will get your engine right in the sweet spot, and keep it there.
No more pushing the redline to get full power in next gear as you need with your long legged, 5 or 6 speed manual transmission.

Fitment
The kit fits all Skyline GTR models with the use of a R32/33 transfer
The F-series DCT suits both the 4.11 (R32/33) and 3.545 (R34) final drive.
No modifications are needed for the transfer case.
A new CNC machined mechatronics cover has been made to clear the front propeller shaft. The main mechatronics connector needs to be removed to clear the cover/propeller shaft.
This cover is designed to house bulkhead connectors and run wiring directly through the cover. Full detailed wiring instructions can be found under "Tech Info"
Please note that trimming of the DCT transmission webbing and some clearing in the trans tunnel is required to fit the kit. (No trimming needed for R34 GTR owners)
The conversion is 100% reversible back to stock
DCT output shaft
You need to send us your DCT output shaft for re-splining and hardening
DHL Express shipping service for the shaft is included in the kit price
(let us know when you have removed the shaft, and we will send you a shipping label)
We have a few modified shafts ready on an exchange basis, and your kit will be sent out once your output shaft is received and inspected.
Removing the axle is a 15min job with a good puller and basic tools
- Remove axle nut and pull off output flange.
- Remove rear cover and place it on a stable platform.
- Tap out the axle with a suitable hammer and send to us.
