1997-2001 Honda Prelude / Accord Euro R H22A JDM Engine | Low Compression Cylinder 3 - Project Motor
1997-2001 Honda Prelude / Accord Euro R H22A JDM Engine | Low Compression Cylinder 3 - Project Motor
| Feature | Details |
| Engine Code | H22A (Euro R "Red Top") |
| Displacement | 2.2 Liters (2,157 cc) |
| Configuration | Inline 4-Cylinder DOHC |
| Valvetrain | 16-Valve VTEC |
| Compression Ratio | 11.0:1 (Factory Spec) |
| Block Construction | FRM (Fiber Reinforced Metal) Cylinder Liners |
| Condition | Core/Project Engine (Low Comp Cylinder 3) |
Vehicle Fitments
This JDM H22A Euro R engine is a premium swap candidate for the following North American (USDM) models:
-
1997-2001 Honda Prelude (Base and Type SH)
-
1992-1996 Honda Prelude (H-Series swap)
-
1990-1997 Honda Accord (Popular H22 swap chassis)
-
1994-2001 Acura Integra (Requires aftermarket swap mounts and axles)
Installation & Technical Notes
As a high-performance VTEC engine requiring a rebuild, please note the following technical details:
-
The Euro R Advantage: This engine includes the specific Euro R single-runner intake manifold and the "Red Top" valve cover. These parts alone are highly valuable for H-series enthusiasts.
-
Cylinder 3 Status: The low compression in Cylinder 3 may be attributed to a burnt valve, worn piston rings, or a head gasket breach. A full teardown is recommended before installation.
-
FRM Liners: Please remember that H22A blocks use FRM (Fiber Reinforced Metal) sleeves. If you choose to bore the engine out during the rebuild, you must use FRM-compatible pistons or have the block sleeved with iron liners for traditional forged pistons.
-
OBD Compatibility: This engine is originally OBD2. When installing into an OBD1 chassis (92-95 Civic/90-93 Accord), you must use an OBD1 H22A distributor and an unchipped P13 or chipped P28 ECU.
-
Essential Maintenance (Post-Rebuild): Once rebuilt, we recommend:
-
Timing Belt & Manual Tensioner Conversion: We strongly suggest converting from the failure-prone auto-tensioner to a manual tensioner kit.
-
Valve Adjustment: Set to Euro R factory clearances for optimal VTEC engagement.
-
Fuel: 91+ Octane is mandatory for the 11.0:1 compression ratio.
