Unlock true Honda performance with this JDM K24A / K24A2 2.4L DOHC i-VTEC engine, pulled from the Japanese-spec 2004–2008 Honda/Acura TSX. This high-performance motor comes equipped with the desirable RBB cylinder head, aggressive 3-lobe VTEC camshaft, and high compression pistons—making it one of the best factory-tuned K-series engines available for street or track use.

This engine is a direct counterpart to the U.S.-spec K24A2 found in the Acura TSX but often in better internal condition due to Japan’s strict emissions and mileage standards. The RBB head allows for true VTEC on both intake and exhaust valves, while the 3-lobe camshaft offers excellent high-RPM breathing—ideal for naturally aspirated builds or boosted applications.

Whether you’re replacing a worn motor or upgrading your Civic, RSX, or TSX, this JDM K24A engine delivers dependable power and compatibility with many K-series platforms. It’s a preferred option for K-swaps due to its robust internals, strong flow characteristics, and the aftermarket support surrounding the RBB-3 head configuration.

All engines are compression-tested and quality-inspected prior to shipping. At J-Spec Auto Sports, we only import clean, low-mileage JDM engines, offering peace of mind with every purchase. This engine includes our 90-day start-up warranty and is ready for installation with your existing intake manifold, harness, and ECU components.

If you’re looking for a plug-and-play high-performance K-series engine, this K24A / K24A2 with RBB head is a proven and powerful choice.
