High oil temperatures under sustained load can quickly reduce lubrication quality and shorten the life of an RB26DETT. The GReddy/Trust 10-Row Oil Cooler with Relocation Kit (part number 12024420) is a vehicle-specific system developed for the Nissan Skyline R33 GT-R (BCNR33), providing effective oil temperature control for both street and high-performance use.
This kit centers on a durable GReddy 10-row oil cooler core (NS1010G) that mounts in front of the radiator for maximum airflow. It includes a 3/4-16 UNF block adapter, a remote thermostat that allows the engine to reach operating temperature efficiently 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 access. High-quality –10 AN steel-braided aerospace lines and fittings complete the plumbing, while vehicle-specific brackets support a clean, secure installation.
By increasing oil capacity and improving heat rejection, the system helps maintain more consistent oil temperatures during hard driving, track sessions, or elevated boost operation. Note that installation requires modification to the guide air plate, fender protector, and under cover, and the kit is not compatible with N1-specification vehicles.
