About the JDM Honda K24A 2.4L DOHC VTEC Engine with 6-Speed Manual Transmission

Upgrade your vehicle’s performance with the JDM Honda K24A 2.4L DOHC i-VTEC Engine paired with a 6-Speed Manual Transmission. This powerful engine and transmission combination is designed to deliver exceptional performance and reliability, making it the perfect choice for enthusiasts, K-swap builders, and professional installers. The K24A3 is the highest-compression factory K24 variant (11.0:1), originally found in JDM Accord Euro-R and Acura TSX applications producing approximately 190 to 200 hp.

What Sets This Listing Apart

This is NOT the same as our standard Honda K24 listing (SKU vaz64 at $999). The key differentiators:

• JDM Imported: Sourced directly from Japanese Domestic Market vehicles, typically Accord Euro-R, JDM Acura TSX, or Accord Type-S

• 6-Speed Manual Transmission Included: This package includes both the engine AND the 6-speed manual transmission as a matched pair

• K24A3 Variant: The highest-compression K24 variant (11.0:1) for maximum performance

• Lower Price Point ($650): Reflects “as-is JDM core” condition, ideal for builders and rebuilders

For buyers needing a turn-key tested K24 long block with full inspection documentation and compression test results, see our standard Honda K24 Engine for Sale (SKU vaz64) at $999. For builders looking for the complete JDM drivetrain package at the lowest price point, this listing is the right choice.

Compatible Cars for the JDM Honda K24A Engine

This JDM Honda K24A engine and 6-speed transmission package is compatible with a wide range of Honda vehicles, including but not limited to:

• Honda Accord: Especially desirable for early 2000s Accord owners seeking the high-compression Euro-R / Type-S configuration

• Honda CR-V: With appropriate motor mounts and ECU configuration

• Honda Element: Direct K24-series compatibility

• Honda Civic Si: Particularly the 8th generation Civic Si and earlier K-swap candidates

• K-Swap Projects: Civic EG (1992 to 1995), EK (1996 to 2000), EM (2001 to 2005), EP (2002 to 2005), Integra DC2 (1994 to 2001), DC5 (2002 to 2006)

Key Features of the JDM Honda K24A Engine Package

1. Enhanced Performance: The K24A3 is known for impressive power output and aggressive torque delivery thanks to its 11.0:1 compression ratio and JDM-spec cam profiles. Whether you’re looking for improved acceleration or increased horsepower, this engine delivers exceptional naturally-aspirated performance.

2. Reliable and Durable: Crafted with precision and high-quality materials, the K-series is built to last. The aluminum block with iron sleeves, forged crankshaft, and chain-driven cams (no timing belt service required) provide long-lasting durability. Honda K-series engines are known to last 250,000+ miles when properly maintained.

3. Advanced i-VTEC Technology: Equipped with i-VTEC (intelligent Variable Valve Timing and Lift Electronic Control) technology, this engine optimizes valve timing AND valve lift for both low-end torque and top-end power. Experience smooth and responsive performance throughout the entire RPM range, with the characteristic Honda “VTEC kick” at high RPM.

4. High Compression Ratio: The 11.0:1 high compression ratio of the K24A3 enhances combustion efficiency, resulting in improved power output, sharp throttle response, and good fuel economy when not pushed hard. Premium 91+ octane fuel is recommended.

5. Complete 6-Speed Manual Drivetrain Package: The included 6-speed manual transmission means K-swap builders get the matched gear ratios designed for the K24A3’s RPM and power characteristics. No need to source a separate transmission or worry about gearing mismatches.

6. JDM Quality and Reliability: JDM (Japanese Domestic Market) engines are known for typically lower mileage than US-market engines (Japan’s stricter inspection laws often retire vehicles at lower mileages) and for being engineered to JDM specifications which often included higher-output cam profiles and ECU calibrations than US-market equivalents.

7. Easy Installation for K-Swap: Designed to fit into a wide range of compatible Honda chassis with appropriate K-swap kits, mounts, and harness adapters. Get back on the road with a complete drivetrain solution.

Value to the Customer

• Integra DC2 / DC5 K-Swap: Direct K-series swap into Integra chassis, with the 6-speed providing better gear spacing than the original 5-speed

• Accord Repower: For 2003 to 2007 Accord owners wanting the higher-compression K24A3 in place of a worn K24A4

• Restoration / Project Builds: Complete JDM drivetrain for any project requiring authentic K24 power

• Engine Builders: Starting point for built engine projects, with included transmission saving sourcing time

Note on JDM Sourcing

JDM-imported engines and transmissions come from Japanese vehicles that have been retired from service in Japan and shipped to the United States. JDM engines are typically lower mileage than equivalent US-market engines because of Japan’s vehicle inspection (Shaken) system that incentivizes vehicle retirement at lower mileage. However, JDM engines are sold “as JDM” meaning specific donor mileage is often not verifiable, and the unit comes as a matched engine + transmission “clip” package without complete documentation history.

Common K24A3 / K-Series Considerations

Like all K-series engines, this engine has the same general inspection points as our standard Honda K24:

• Timing chain stretch (a known K-series wear item)

• VTC actuator function (the variable timing control unit on the intake cam)

• Oil consumption (a concern on higher-mileage K-series, less common on JDM-spec engines due to typically lower mileage)

• i-VTEC system function

We compression test all four cylinders before shipping and disclose any concerns openly.
