High Compression K24A RBB-2 Engine.

Looking for a high-performance upgrade for your Honda build? J-Spec Auto Sports is proud to offer this JDM Honda K24A RBB-2 high compression engine – imported directly from Japan and ready for your next performance project. This 2.4-liter DOHC i-VTEC motor features the RBB-2 head, known for its compatibility with VTEC’s 3-lobe camshaft design, making it a powerful and reliable choice for enthusiasts looking to get the most out of the K-series platform.

This specific K24A RBB-2 engine came equipped in the Japanese Honda Accord CL7/CL9 and offers higher compression pistons compared to the U.S. DM variants like the K24A2. It’s a favorite among tuners for its compatibility with RSX Type S or TSX ECUs, and makes an excellent base for K-swap projects in Civics, Integras, or even rear-wheel-drive conversions.

• K24A 2.4L DOHC i-VTEC Longblock

• RBB-2 Head with true 3-lobe VTEC

• OEM High Compression Pistons

• Clean, low-mileage unit from Japan (compression tested)
