The Nissan SR20 engine series, including the naturally aspirated SR20DE and the legendary turbocharged SR20DET, remains one of the most versatile and reliable four cylinder platforms ever built for street and motorsport applications. Found in iconic models like the Nissan Silvia S13, S14, and S15, as well as the 180SX and Pulsar GTI-R, this lightweight aluminium block motor offers massive high power tuning potential and endless aftermarket support. While factory setups are tough, pushing past stock limits means upgrading critical weak points like the factory valvetrain, rocker arms, and head gasket to prevent catastrophic engine failure if constantly pushing the limits under high boost.

Our comprehensive range of Nissan SR20 engine parts is curated to help you build a bulletproof setup that handles serious abuse on the street, strip, or drift track. We stock everything from heavy duty forged pistons and stronger connecting rods, to upgraded valve springs, rocker arm stoppers, and premium multi-layer steel MLS head gaskets.
