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.

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

- 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.

Condition and Inspection
Every JDM Honda K24A engine + 6-speed manual transmission package we ship goes through this process:
- Compression test across all 4 cylinders, pressure per cylinder recorded
- i-VTEC system function verified
- VTC actuator condition checked
- Timing chain visual inspection
- 6-speed transmission shifted through all gears (forward and reverse) with engagement feel assessed
- Transmission case inspected for cracks
- Engine and transmission shipped together as matched pair from same JDM donor
- Donor source identified when verifiable (JDM Accord Euro-R, TSX, Type-S)
JDM engines typically come with less verifiable history than US-market engines, but Japan's stricter inspection regime usually means lower-mileage donors. We disclose all known information openly before payment.
