ISR Performance Radiator Fan Shroud Kit - Nissan SR20DET S14

The ISR Performance Radiator Fan Shroud Kit is a direct OEM-fit electric fan and shroud assembly for the 1995-1998 Nissan 240SX (S14) with an SR20DET swap. Dual 12 inch electric fans mounted in a lightweight reinforced shroud, designed to maximize airflow through an aftermarket performance radiator on an SR20DET-swapped S14.

What It Does

SR20DET-swapped S14s run hotter than KA24 cars, and the factory shroud was never designed around a turbocharged engine pushing more heat into the cooling system. This kit replaces the factory shroud and fan setup with dual 12 inch electric fans in a purpose-built shroud, sized to fit the SR20DET-swap radiator hose orientation in the S14 chassis.

The shroud frame secures the fan blades on all sides, preventing blade damage to surrounding engine components if a blade contacts something at high RPM. Lighter and more durable than the factory shroud.

Best Paired With an Aftermarket Radiator

This shroud kit is at its most effective when paired with a performance aluminum radiator. For SR20DET-swapped S14, that's typically the SR20DET-specific aluminum radiator option. Running this shroud with the factory KA24 radiator works, but you're not getting the full cooling benefit.

Fitment
