Description

Revive your Honda with this JDM K20A (K20A3) 2.0L i-VTEC engine, directly imported from Japan and specifically designed for the 2002–2005 Honda Civic Si EP3 chassis. If you’re experiencing engine failure, power loss, or just want to refresh your ride with a reliable OEM motor, this JDM K20A is the perfect solution.

This engine is the Japanese equivalent of the U.S. K20A3, offering the same base 2.0L DOHC i-VTEC layout with a redline of 6800 RPM. Known for its solid performance and long-term reliability, the K20A is a popular and cost-effective upgrade for EP3 owners looking for a direct drop-in replacement.

Each engine is fully compression tested and carefully inspected for leaks, internal wear, and mechanical health before shipping. As a Japanese Domestic Market (JDM) import, the motor typically has lower mileage (approx. 45K–60K miles) due to Japan’s strict vehicle retirement laws.

  • Compression Ratio: 9.8:1
