SP Engineering is proud to announce our 3 tiers of tuning solutions for the R35 GTR VR38DETT. After months of R&D and tuning performance upgrades for the GTR, SP Engineering has enhanced every aspect of the R35 from raising the factory boost levels to upgrading the factory turbo system. Utilizing both of our in-house AWD Mustang Dyno and 2WD Dynojet, we have been able to design the perfect tuning map to suit whichever package fits your needs. Each package has been specially put together for one primary purpose; to extract the appropriate amount of power from your motor, without sacrificing safety and reliability.
