ISR Performance OE Replacement Engine Gasket Kit - Nissan SR20DET S13

The ISR Performance OE Replacement Engine Gasket Kit is a complete gasket and seal set for the 1989-1994 Nissan S13 SR20DET. Includes every gasket, seal, and O-ring needed for a full engine rebuild or top-end refresh, from main seals and valve cover gaskets through turbo flange gaskets and injector O-rings. Race-engineered for high horsepower and compression applications.

What It Does

An engine rebuild is no time to save five dollars on gaskets and end up with a leaking engine three months later. This kit covers every sealing surface on the S13 SR20DET in one purchase, so you're not chasing individual part numbers across multiple orders or finding out at 11pm that you forgot the oil pickup tube gasket. Everything is here, sized correctly for the S13 RWD SR20DET application, and built to handle the pressures and temperatures a built SR puts out.

Fitment

• 1989-1994 Nissan 240SX (S13) with SR20DET swap
• Designed for the RWD (rear-wheel-drive) SR20DET specifically

FWD SR20DET note: This kit is for the RWD SR20DET. Some gaskets are shared with the FWD SR20DET, but others (intake manifold orientation, exhaust manifold, valve cover) are not. Don't use this kit for an FWD SR rebuild.
