RBB Head & 3-Lobe i-VTEC Camshaft

One of the most important features of this engine is its RBB cylinder head with a 3-lobe i-VTEC camshaft.

Therefore, this is not a generic K24 replacement. Buyers specifically searching for an RBB-head K24A should pay close attention to the cylinder-head and camshaft configuration when comparing JDM engines.

The 2.4-liter displacement also provides strong torque while retaining the high-revving character that helped make Honda’s K-Series popular with enthusiasts.

Acura TSX K24A2 Replacement

This JDM K24A can serve as a replacement option for compatible Acura TSX applications originally equipped with the K24A2.

However, the Japanese-market K24A and U.S.-market K24A2 are not identified by the same engine code. Therefore, installation may require transferring specific components from your original engine.

Depending on the vehicle and application, you may need to reuse original accessories, sensors, wiring, intake/exhaust components or other external parts.

For that reason, do not purchase based on the K24 designation alone. Contact J-Spec Auto Sports with your VIN, year, make, model and original engine code so we can help verify compatibility.

Compression Tested

J-Spec Auto Sports tests our JDM engines before sale. For this engine, we perform a compression test to evaluate cylinder sealing and overall engine condition.

Furthermore, customers can request available testing information before purchase.

What’s Included?

This listing is for the K24A engine assembly shown in the product photos.

Accessories attached to a used JDM engine may remain for convenience. However, unless we specifically guarantee an accessory in writing, buyers should consider those external components complimentary and plan to reuse the appropriate components from the original vehicle when necessary.

Recommended Before Installation

For the best installation result, we recommend inspecting or replacing normal service items before installing a used engine.

Consider servicing:

• Engine oil and filter
• Spark plugs
• Valve cover gasket if needed
• Front and rear crankshaft seals as needed
• Accessible coolant hoses
• Thermostat as needed
• Drive belt and tensioner as needed
• Other accessible seals and maintenance components

In addition, prime the lubrication system before initial startup, fill the cooling system correctly and bleed all trapped air before road testing.

90-Day Warranty

Professional installation and proper pre-installation service help protect both the engine and your investment. Therefore, review our complete warranty requirements before installation.
