Note on Transfer Case Oil Pump Gear Size:
Our oil pump covers are supplied to suit the standard 5.5 mm thickness gear. Some early 1989–1990 GTR models were fitted with a 7 mm oil pump drive. If you own an early model, we recommend checking the thickness of your gear before placing an order.
If you confirm your gear size with us before your order ships, we can supply the correct cover at no extra cost. If you’ve already purchased a kit with a 5.5 mm cover but require the 7 mm version, we can provide it separately at cost price.

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.
