Description

Mazda RX-7 FD (93-95) with LS V8 swap Mishimoto aluminium radiator

The Mishimoto radiator RX-7 LS-swap is an aluminium radiator designed specifically for the 1993-1995 Mazda RX-7 FD in which the original rotary has been replaced by a GM LS V8. Please note: this is not a radiator for an RX-7 with the stock 13B engine.

An LS swap needs a cooling solution that suits both the V8 and the tight nose of the FD. This bolt-in radiator makes the swap a lot easier. It has a brazed two-row aluminium core 55 mm thick, TIG-welded end tanks and works with naturally aspirated as well as turbocharged or supercharged engines, on the street and on track.
