ISR Performance Aluminum Radiator - Nissan S14 240SX 95-98 SR20DET Swap

The ISR Performance Aluminum Radiator for the S14 240SX with SR20DET swap is a TIG-welded aluminum radiator built as a direct drop-in upgrade over the factory unit. Better cooling efficiency for daily-driven SR builds, and serious cooling capacity margin for track and higher-power applications. Chassis-specific design (S14), not motor-specific.

What It Does

A larger, more efficient aluminum radiator handles the heat that a hard-driven SR20DET dumps into the cooling system. Stock 240SX cooling capacity is marginal even with the factory KA24DE; once you've put an SR in there and started making boost, the factory radiator can run out of margin fast. The ISR unit is TIG-welded lightweight aluminum construction with significantly more core capacity than the factory unit. Direct drop-in fit using factory mounting points on the S14 chassis.

Fitment

Designed for the Nissan 240SX 1995-1998 (S14 chassis) with SR20DET swap. Chassis-specific fitment, not motor-specific. the radiator is designed around the S14 engine bay layout. For S13 SR builds, the S14 radiator will not bolt up directly. Pairs naturally with the IS-FS-SRS13-style dual electric fan shroud kit if your S14 build uses similar cooling architecture (verify shroud fitment separately).
