Collection: SR Engine Collection

Power up your S-chassis build with the SR20DET engine parts you need. The SR20DET is the definitive engine for Nissan 240SX engine swaps, S13 and S14 competition builds, and remains one of the most popular drift and performance platforms in the world — and J-Spec Garage stocks a comprehensive range of SR20 components to support every build level.

Our SR engine catalog includes forged pistons, connecting rods, camshafts, head studs, valvetrain upgrades, oil system components, and fuel system parts from Brian Crower, GSC Power Division, Tomei, Injector Dynamics, and Radium Engineering. Whether you're building a 300 hp street car for weekend autocross or a 500+ hp competition car, we have the SR20DET internals and supporting mods to get it done reliably.

We also carry SR20DE components for naturally-aspirated applications and KA24DE parts for stock-engine 240SX builds. J-Spec Garage backs every order with our price match guarantee.
