Consistent oil temperature control is critical for protecting a high-output RB26DETT under sustained load. The GReddy/Trust 13-Row Oil Cooler with Relocation Kit (part number 12024431) is a vehicle-specific system developed for the Nissan Skyline R34 GT-R (BNR34), delivering increased cooling capacity and improved oil management for both street and performance driving.
This kit centers on a durable GReddy 13-row oil cooler core that mounts in front of the radiator for strong airflow exposure. It includes a 3/4-16 UNF block adapter, a remote thermostat that allows the engine to reach normal operating temperature before routing oil through the cooler, and a remote oil filter relocation adapter that moves the filter to the right strut tower area for easier service access. High-quality –10 AN steel-braided aerospace lines and fittings, along with vehicle-specific mounting brackets, complete a clean and purpose-built installation.
The larger 13-row core increases oil volume and heat-rejection surface area, helping stabilize oil temperatures during extended hard driving, track use, or elevated boost conditions. By reducing thermal stress on the oil and internal engine components, the system supports more consistent lubrication and longer component life on the RB26DETT.
At Terra Firma Automotive, we supply this genuine GReddy/Trust Oil Cooler Kit as a proven, application-engineered solution for R34 GT-R owners who demand reliable oil temperature management. Choose Terra Firma Automotive for authentic Japanese performance parts that help maintain the durability and consistency of the legendary RB26 engine.
