The Honda H22Z1 is a 2,259 cc, inline‑four naturally aspirated petrol engine produced between 1997 and 2001. It features a dual overhead camshaft (DOHC), 16‑valve design with Honda's VTEC system, engineered for high-revving performance and strong power delivery. Peak output is 147 kW (200 PS) and 220 Nm of torque, making it a popular choice for enthusiasts seeking a balance of power and reliability.
Fitted primarily to the fourth-generation Honda Prelude (BB6/BB8 chassis) in Japanese and European markets, including the Prelude Type S and SiR trims, the H22Z1 was designed for spirited driving and precise handling. Emissions compliance for its production period was met through electronic fuel injection and catalytic converter systems, aligning with Euro 2 standards.
One documented service concern is wear in the VTEC oil pressure switch, potentially causing delayed or failed VTEC engagement and triggering a 'Check Engine' light. This issue, addressed in Honda Service Bulletin 98-062, is often linked to oil contamination or electrical failure, necessitating switch replacement to restore proper function.

Production years 1997–2001 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/8915).
The Honda H22Z1 is a 2,259 cc inline‑four naturally aspirated petrol engine engineered for sport coupes (1997-2001). It combines DOHC VTEC with PGM-FI fuel injection to deliver high-revving power and responsive performance. Designed to meet Euro 2 standards, it balances track-inspired performance with road-going practicality.

The DOHC VTEC design provides exhilarating high-RPM power but requires clean, high-quality oil to ensure reliable operation of the VTEC solenoid and prevent clogging of the oil passages. Using the specified 5W-30 oil and adhering to 10,000 km service intervals is critical. The timing belt requires replacement every 90,000 km. The engine's high compression ratio demands premium unleaded fuel (RON 95 or higher) to prevent detonation. The engine's non-interference design offers a safety margin if the timing belt fails.
Oil Specs: Requires API SJ/CF specification, SAE 5W-30 viscosity (Honda Owner's Manual, 1999 Prelude).
Emissions: Euro 2 certification applies to all 1997-2001 models (VCA Type Approval #VCA/EMS/8915).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model years (Honda TIS Doc. H-ENG-011).

The Honda H22Z1 was used across Honda's BB6/BB8 Prelude platform with transverse mounting. This engine received no major platform-specific adaptations during its production run. All applications are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the engine block, near the timing belt cover (Honda TIS H-ENG-ID). The 8th digit of the VIN for H22Z1-equipped Preludes is typically 'H'. Visually, the engine features a black plastic VTEC solenoid on the cylinder head's rear and dual camshaft covers with 'VTEC' embossed. Critical differentiation from the H22A: The H22Z1 has a higher compression ratio (10.6:1 vs. 10.0:1) and a specific ECU with a 'P13' code. Service parts like the cylinder head and ECU are not interchangeable with non-VTEC variants.
The H22Z1's primary reliability consideration is VTEC system functionality, with potential issues arising from neglected oil changes or electrical faults. While generally robust, UK DVSA data notes ignition coil failure as a common cause of misfires in high-mileage examples. Maintaining clean oil and ignition components is critical for long-term performance.
Analysis derived from Honda technical bulletins (1997-2002) and UK DVSA failure statistics (2001-2011). Repair procedures should follow manufacturer guidelines.
