The Nissan GTR has an unequalled race heritage as does C&R Performance race winning radiators. Built to keep the VR38DETT twin-turbo V6 cool. Made in Austraila using race proven 42mm core, this is the highest quality alumium radiator you can use. Most radiator manufactures use off the shelf cores that were designed in the early 80's. But not C&R , as with all applications, street or race, they take the time to design proper core for each application and coupled with using modern CNC manufacturing and skilled professional fabricators and welders gives the customer a real advantage. Being part of the PWR group, they make their own core. This gives them much better control and results.
