Mishimoto Performance Aluminium Radiator For Nissan Skyline R33 GTST RB25DET & R34 GTT RB25DET NEO MMRAD-RHD-R33

The Mishimoto Performance Aluminium Radiator is a premium cooling system upgrade developed for the Nissan Skyline R33 and compatible R34 models equipped with Nissan's legendary RB-series turbocharged engines. Designed by Mishimoto, this high-capacity aluminium radiator offers improved cooling efficiency, increased coolant capacity and exceptional durability, making it an excellent choice for enthusiasts upgrading their factory cooling system.

Manufactured entirely from aluminium, the Mishimoto radiator features a high-efficiency three-row brazed cooling core combined with durable TIG-welded aluminium end tanks. This construction provides improved strength and resistance to thermal stress compared with conventional factory radiators featuring plastic end tanks, making it particularly suitable for demanding performance applications.

At the heart of the radiator is a 40mm thick aluminium core designed to maximise heat dissipation and improve cooling system efficiency. The increased cooling capacity helps maintain consistent engine operating temperatures during prolonged periods of high engine load, particularly when driving on circuits or operating a modified turbocharged engine.

Mishimoto has developed this radiator to improve cooling efficiency by up to 30% under its stated performance claims. This makes it a practical upgrade for Nissan Skyline owners seeking additional cooling performance beyond the original radiator, particularly on vehicles equipped with upgraded turbochargers, increased boost pressure and other engine modifications.

The fully aluminium construction incorporates TIG-welded end tanks, helping eliminate the weaknesses commonly associated with ageing plastic radiator tanks. This provides a durable cooling system solution for enthusiasts restoring older Nissan Skylines or preparing their vehicles for demanding road and motorsport use.

The Mishimoto Performance Aluminium Radiator is also supplied with a high-pressure 1.3 bar radiator cap. This increases the pressure maintained within a compatible cooling system, helping raise the boiling point of the coolant and providing additional resistance to overheating during demanding operating conditions.

An additional feature is the included magnetic drain plug, which is designed to capture ferrous metallic particles circulating within the cooling system. This provides a useful maintenance feature while allowing coolant to be drained during routine servicing.

Designed primarily for manual transmission Nissan Skyline R33 applications, this radiator is also listed for selected R34 RB25DET applications. However, compatibility should be confirmed against the vehicle's original radiator configuration, mounting points and hose connections before purchasing.

For Nissan Skyline R33 GT-R BCNR33 models equipped with the RB26DETT engine, Mishimoto specifies that modification is required during installation. This radiator is therefore not considered a direct-fit replacement for the GT-R application, and additional fitting work may be necessary.

Whether maintaining a standard Nissan Skyline, replacing an ageing factory radiator or preparing a modified RB25DET or RB26DETT engine for demanding performance use, the Mishimoto Aluminium Radiator offers an effective combination of improved cooling capacity, durable construction and high-quality engineering.

Available from JDM Part Shop., the Mishimoto Performance Aluminium Radiator is an excellent choice for Nissan Skyline enthusiasts seeking a reliable aftermarket cooling upgrade designed to support consistent engine temperature management during both road and circuit use.
