JDM 2002–2005 Honda Civic Si / Acura RSX (Base) K20A 2.0L i-VTEC Engine
Japanese-domestic K20A 2.0L i-VTEC inline-4, imported direct from Japan — a sought-after swap/replacement for the Civic Si (EP3) and RSX base. We keep this engine in regular rotation from our container imports: clean, low-mileage units (typically 45,000–65,000 miles), compression-tested and auction-graded.
What you get
You'll transfer your original ECU, wiring harness and external accessories. When you order, we pull a clean in-stock unit and send photos and the serial of the actual engine before it ships — real engines, never stock photos.
Fitment
Interchanges with Civic Si (EP3) and Acura RSX base applications; confirm fitment with your mechanic before ordering.
Warranty
90-day replacement-engine warranty — full terms at jdm-online.com/pages/warranty.
