NISMO Engine Oil Cooler Kit For Nissan Skyline R32 GTR

Track sessions and high-boost street use push RB26 oil temperatures well beyond what the factory cooler can comfortably manage. The NISMO Engine Oil Cooler Kit (part number 21300-RRR20) is the R32-specific air-cooled package for the Nissan Skyline GT-R (BNR32). Unlike the later R33 and R34 versions of this kit, NISMO lists the R32 application for all BNR32 cars, so it is intended to work with the standard R32 front-end layout rather than requiring a NISMO bumper.

The cooler itself uses a compact 19-row aluminum core measuring 140 mm high, 294 mm wide, and 50 mm deep. An aluminum air guide, assembled with rivets, is included to channel air through the core instead of allowing it to bypass the stack. Stainless-mesh feed and return hoses come with #10 fittings already installed, and the kit also includes the oil-filter bracket and mounting hardware needed to complete the conversion. The design adds oil capacity and heat rejection so the RB26DETT can hold more stable oil temperatures during hard driving.

This is a genuine NISMO system rather than a generic core with homemade lines. That matters on an R32 GT-R, where space in the nose is limited and a poorly placed cooler can hurt airflow to the radiator or intercooler. Installed correctly, the kit helps protect bearings, turbos, and oil life when the engine is worked hard on circuit, mountain roads, or in hot climates.
