{"product_id":"8hp-to-gtr-conversion-kit","title":"8HP to GTR Conversion Kit","description":"The HPR Tuning Superior 8HP to GTR Conversion Kit provides a comprehensive solution for integrating an 8HP transmission into your Nissan Skyline GTR.\n\nThe kit features precision-machined components, including HPR's signature billet bellhousing and flexplate, which ingeniously merge the 8HP centerplate into a singular unit. Developed using advanced metrology-grade 3D scanners and Geomagic Design X software, the Superior Kit aims to set a new standard for transmission upgrades, ensuring a premium feel and an enhanced driving experience for Skyline GTR enthusiasts.\n\nKey advantages of this kit include no chassis modifications required for all Skyline GTR models, no cutting needed in the bellhousing for starter or front propshaft clearance, and it matches the length of the factory R34 GTR Getrag transmission. It also eliminates the need for a custom front propshaft, with a spacer kit included for R32\/R33 users and a direct fit for R34 models. The kit includes a durable billet steel flexplate and is designed for 100% bolt-in installation with stock propshafts for the R34 GTR. The included prepped HPR 8HP transmission is rated for 1000hp\/1000nm.\n\nIncluded in the full package are a prepped HPR 8HP transmission with billet bellhousing, a billet 4340 flexplate with ARP hardware, a modified stock converter, breather mod-kit, Nissan RB dust shield, a 3-piece billet crossmember kit with 60A rubber mounts, a rear adapter kit for the Skyline GTR, a billet 7075 aluminum oil pump cover, shifter components, a front propshaft spacer kit, and all necessary installation hardware. Accessory items include an HPR 8HP Thermostat oil pan, a Setrab 8HP 625 oil cooler kit, a DCT shifter, an HPR Nissan S\/R chassis shifter plate with wiring grommet, a CANFormance transmission control unit, a CANTCU 8HP plug-and-play wiring harness, and a CAN Keypad.\n\nItems not included are rear propshaft modification (required for R32\/R33 models), transmission oil, and an upgraded torque converter (a stock unit is provided). The transmissions are sourced from BMW vehicles with the N57 engine and come with a 90-day warranty. It is critical to note that the R34 GTR transfer case is not compatible with this kit. R32\/R33 GTR front propshafts require the included spacer kit for proper fitment, while R34 users can retain their stock propshaft. Compatibility of your ECU with the CANFormance CANTCU should be verified via their provided wiki link. Additionally, early 1989–1990 GTR models might have a 7mm oil pump drive gear instead of the standard 5.5mm; confirmation with HPR Tuning is recommended before ordering if you have an early model. This product is a custom order and non-refundable, with lead times potentially up to 12 weeks.","brand":"HPR Tuning","offers":[{"title":"Default Title","offer_id":52688701784376,"sku":"HPR-8HP-GTR-SUP","price":124.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664206256.webp?v=1784893203","url":"https:\/\/store.motormia.co\/products\/8hp-to-gtr-conversion-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
