Circuit driving places extreme thermal demands on the RB26DETT, making dedicated oil temperature control essential. The GReddy/Trust 13-Row Circuit Spec Oil Cooler with Relocation Kit (part number 12024432) is a high-capacity, competition-oriented system developed specifically for the Nissan Skyline R34 GT-R (BNR34), designed to deliver maximum cooling efficiency under sustained high-load conditions.
This Circuit Spec kit features a large 13-row GReddy oil cooler core and is engineered to work with the NISMO front bumper’s air intake and outlet duct layout. The core mounts in the left front bumper/fender area, and the kit includes an FRP air duct that channels airflow directly through the cooler for improved heat rejection. A remote thermostat allows normal warm-up before directing oil through the core, while the remote oil filter relocation adapter moves the filter for better service access. Lightweight –10 nylon mesh hose and GReddy fittings complete the plumbing, supported by vehicle-specific brackets.
Intended for circuit and competition use, this kit prioritizes cooling performance over street practicality and is not designed for standard road use with the factory bumper. It requires a NISMO front bumper for proper fitment and airflow utilization. For R34 GT-R owners focused on track durability and consistent oil temperatures under extreme conditions, this is one of the most purpose-built solutions available.
