Show original supplier description
The LOJ Conversions LSx Swap Street Radiator is engineered for LSx engine swaps into Z32 300ZX vehicles, offering superior cooling performance while preserving air conditioning functionality. Manufactured for LOJ by C&R Racing, it boasts fully TIG-Welded construction and utilizes a Denso radiator core, the same technology employed in C&R's NASCAR radiators. This radiator is designed for a direct drop-in installation into the lower mounts of both naturally aspirated (NA) and twin-turbo (TT) 300ZX models. It requires no modifications to the upper mounts for the AC condenser or the wiring harness located under the upper radiator support. The unit comes pre-installed with two 11-inch High Output SPAL fans and includes a Billet Aluminum LOJ Radiator Cap. While this radiator is considered the best and most efficient option for LSx conversions in Z32 300ZXs for street, drag, and autocross use, it is not recommended for cars experiencing extended track use in hot climates. For such extreme racing conditions, LOJ suggests their race radiator and the removal of air conditioning.
