JDM Honda Civic Si 2006–2011 engines in Los Angeles

Looking for a replacement K20A / K20Z for a Honda Civic Si 2006–2011? This page lists every Japanese-market K20A / K20Z engine in our Vernon, CA warehouse tagged to fit the 2006–2011 Civic Si. These are low-mileage imports pulled from vehicles in Japan, graded at auction, compression-tested when they land and photographed on our floor — the unit count updates live as containers arrive and units sell.

Performance and upgrade engines carry a 30-day warranty plus a 30-day return window; transmissions carry 30 days. The period starts the day the unit arrives. Pick up at our Vernon warehouse in LA County, use our local delivery zones across Southern California, or have it crated and shipped by freight anywhere in the mainland US.

Not sure which K20A matches your Civic Si’s trim, transmission or emissions setup? Text or call (442) 888-0318 with your VIN and we will confirm fitment before you order, or use the fitment finder to check another vehicle. Full terms are on our warranty page.
