Show original supplier description
The LOJ Conversions LSx Swap Race Radiator is a purpose-built cooling component engineered for LS engine installations in the 300ZX (Z32) chassis. Constructed with fully TIG-welded seams and a robust 3-inch thick PWR radiator core, this unit is designed to provide superior cooling performance under demanding conditions. It is the only radiator recommended by LOJ for their LS swap kits when maximum cooling is paramount. This race radiator comes equipped with one 16-inch High Output SPAL fan pre-installed on the rear, and features a mounting ring on the front to accommodate an additional 16-inch pusher fan if desired. A billet aluminum LOJ Radiator Cap is also included, completing the package. Installation of this radiator requires several modifications. These include alterations to the upper radiator support, removal of the factory hood latch, and the complete removal of the vehicle's Air Conditioning system. Additionally, the installation of hood pins is necessary. Radiators are built to order and have an approximate lead time of three weeks from the date of order placement.
