Honda Type R 2.0L K20Z engine
R32,500.00
The Honda K20Z series represents a refined evolution of the high-performance K20A architecture, specifically designed to meet modern emissions standards while maintaining a high-revving character. In the Type R lineage, this engine is most famously associated with the K20Z4 variant found in the European Honda Civic Type R (FN2).
Engine Specifications (K20Z4)
The K20Z4 is a naturally aspirated, 2.0-litre inline-four that serves as the final high-RPM, non-turbocharged engine in the Civic Type R’s history.
| Feature | Specification |
|---|---|
| Displacement | 1,998 cc |
| Power Output | 148 kW (201 PS / 198–201 hp) @ 7,800 rpm |
| Maximum Torque | 193 Nm (142 lb-ft) @ 5,600 rpm |
| Bore x Stroke | 86.0 mm x 86.0 mm (“Square” design) |
| Compression Ratio | 11.0:1 |
| Redline | 8,000–8,200 rpm |
Key Design Features
- Refined i-VTEC: Features an enhanced i-VTEC system that adjusts valve timing and lift on both intake and exhaust cams to optimise mid-range torque and high-RPM power. VTEC engagement typically occurs at 5,400 rpm.
- Balance Shafts: Unlike some track-focused K20A variants, the K20Z series often includes balance shafts to reduce vibrations, making it smoother for daily driving.
- Drive-by-Wire: Includes an electronic throttle body for smoother torque delivery and improved fuel efficiency compared to earlier cable-actuated systems.
- Durability: Built with an aluminium block and head, featuring forged internals and a robust timing chain designed for long-term reliability.
Other High-Performance K20Z Variants
While the K20Z4 is the primary Type R version, other “Z” engines share its performance DNA:
- K20Z1: Found in the 2005–2006 Acura RSX Type S, producing roughly 210 hp with a higher 8,300 rpm rev limit.
- K20Z3: Powering the 2006–2011 Civic Si, it produces 197 hp and includes a limited-slip differential (LSD) as standard.
Maintenance Considerations
- Valve Clearances: Requires manual adjustment every 40,000 km to prevent “ticking” and maintain performance.
- Oil Selection: High-quality 5W-30 or 10W-30 fully synthetic oil is essential to ensure the hydraulic i-VTEC system functions correctly.
- Tensioner: The hydraulic timing chain tensioner should be inspected on high-mileage units to prevent chain “jump”
