The Proof of Our Quality
HPR's responsiveness and dedication to provide their customers with the products and service we require was nothing short of spectacular. It is very obvious when delaing with Helge/HPR that they care very much about their costumers and are extremley passionate about what they do.
- Mitch, USA
"I stumbled upon HPR Tuning online, and that marked the beginning of a remarkable journey. My interaction with Helge, a wonderful member of the HPR team, was truly insightful. Their products are not only exceptional but also backed by an invaluable depth of knowledge. They managed the seemingly impossible task of fitting a BMW gearbox into an R32GTR flawlessly, a feat that was considered implausible. HPR's engineering prowess is truly outstanding." - Gary from the United Kingdom"

"Outstanding communication, top-notch service, excellent products, and lightning-fast shipping. Keep up the fantastic work, folks!"
- Gabriele from Italy
"I'm delighted with our communication. While there was an initial hiccup with my oil adapter not matching my transmission, the HPR team quickly found a straightforward solution. They offered reasonable options, and I'm extremely satisfied with the resolution. I've now put 2,000km on my swap using the HPR oil cooler adapter and PCD cover plate, and I'm looking forward to future business with them.

GTR SUPERIOR DCT KIT | BUY NOW
This is a kit for a conversion with transmission included
BUILD YOUR COMPLETE DCT TO GTR PACKAGE | EVERYTHING YOU NEED: HERE
Introduction
As the true pioneers behind the world's first DCT kit into a Skyline GTR, we are proud to finally reveal the all new Superior DCT kit!
Years of extensive research and development have gone into making this kit. With well over 1500 hours in development alone we have pushed boundaries that we thought were not where possible back in 2020 when we released the first kit!
Every component in the kit has been meticulously chosen to provide a premium feel and an unparalleled, innovative driving experience
Advantages
- The the new Superior kit, no chassis modifications are required in order to install the kit into any of the Skyline GTR models.
- The rotated version of the kit gives end users the option to run the transmission with OEM TCU and gateway control without the need to do any internal modifications to the transmissions wiring.
- Running the DCT with a gateway controller is a huge step forward for all DCT conversions as it does not require any complex setup or tuning, and you will be up and running with the new transmission in just a few hours. No aftermarket controller on the market per now will beat a gateway controller in simplicity and OEM driveability. We highly recommend the Cantcu gateway controller for DCT control.
Description
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.
The GTR Superior 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.
The kit has the same built length as the 6 speed Getrag found in the R34GTR, and even the stock propshafts can be used for R34GTR owners.
The R32 and R33 GTR owners can use the stock front propshaft with a spacer included in the kit, and will need a custom one piece rear shaft. Alternatively, the front part of the R34GTR rear propshaft can be used for a OEM 2 piece propshaft solution with the kit.
