Sustained high loads and elevated boost on the RB26DETT demand effective oil temperature control. The GReddy/Trust 13-Row Oil Cooler with Relocation Kit (part number 12024421) is a vehicle-specific system engineered for the Nissan Skyline R33 GT-R (BCNR33), offering increased cooling capacity through a larger core mounted inside the right front fender.
This kit features a durable GReddy 13-row oil cooler core (NS1310G) with offset internal fins designed to improve heat rejection while limiting pressure loss. It includes a 3/4-16 UNF block adapter, a remote thermostat that permits normal warm-up before directing oil through the cooler, and a remote oil filter relocation adapter positioned at the right strut tower for improved service access. High-quality –10 AN steel-braided lines and fittings, vehicle-specific brackets, and an aluminum air guide complete the package for a purposeful installation.
The larger 13-row core provides greater oil volume and cooling surface area compared with smaller systems, helping maintain more stable oil temperatures during extended hard driving or track use. Installation requires modification to the guide air plate, fender protector, and under cover. The kit is not compatible with N1-specification vehicles, and certain configurations may require the GReddy TYPE-R blow-off valve kit for proper fitment.
