ISR Performance Aluminum Radiator - Nissan 240sx 95-98 w/SR20DET

The ISR Performance aluminum radiator for the 1995 to 1998 Nissan 240SX S14 with SR20DET gives an SR-swapped S14 a cooling system sized for the engine actually in the bay. It installs in the factory location as a direct replacement and is meant to head off the overheating that tends to follow a swap, more power or a day at the track.

Build details

Every ISR radiator is TIG welded from aluminum and comes in well under the weight of the stock unit. The core is comparable in size to the pricier Koyo radiators for the same chassis, and the cooling performance holds up against other aluminum radiators on the market, which makes this one of the better value options for an S14 SR.

Vehicle application

• Nissan 240SX S14, model years 1995 to 1998
• SR20DET engine (swapped)
• Direct drop-in, no cutting or custom mounts

When to install it

ISR recommends doing this upgrade as part of the swap itself or shortly after. A fresh aluminum radiator going in with the motor means you are not chasing a cooling issue later with the car already assembled. It is equally at home on a daily driven S14 whose original radiator has simply worn out.

Pairs well with

ISR silicone SR20DET radiator hoses, the ISR 12 inch electric fan, and the ISR S14 SR20DET fan shroud kit, which bolts to this radiator and carries dual 12 inch fans.

All ISR Performance products are designed for off-road use only.
