Koyo Nissan 240SX V8 Swap/KA24 Turbo Radiator - RH020539N

Koyo Nissan 240SX V8 Swap / KA24 Turbo Radiator – RH020539N

The Koyo RH020539N is a competition-grade aluminum radiator built for high-horsepower S13 projects, including LS-based V8 swaps and high-boost KA24 turbo setups. Designed specifically for the Nissan 240SX chassis, this radiator delivers the cooling capacity and durability needed to keep temperatures stable in extreme conditions.

Featuring a dual-pass N-FLO design, the RH020539N routes coolant through the core twice for maximum heat dissipation. Its 53mm all-aluminum core and high fin density provide a significant increase in cooling efficiency over stock-style radiators, making it ideal for track, drift, and endurance racing. This unit is a direct fit for the S13 chassis, retains OEM mounting points, and works with popular electric fan and shroud configurations used in custom builds.

With TIG-welded end tanks and Nocolok-brazed construction, the RH020539N is built to handle the punishment of big-power builds while delivering consistent, reliable performance.
