Collection: KA Engine Collection

The KA24DE is the durable factory engine of the Nissan 240SX — a stout, underrated foundation for boosted and high-revving builds. J-Spec Garage's KA Collection covers the parts to rebuild, strengthen, and make power with the KA24DE and KA24E in the S13 and S14 chassis.

Shop forged pistons and rods, head studs, camshafts, valvetrain, gaskets, and rebuild components for street, drift, and track KA builds. Whether you're keeping it KA or building a boosted bottom end, we stock the parts to do it reliably — backed by our price match guarantee and fast US shipping.
