1998-2002 Honda Accord SiR / 1997-2001 Prelude JDM H23A "Blue Top" 2.3L DOHC VTEC Engine

Experience the pinnacle of F-series/H-series hybrid performance with this authentic JDM H23A "Blue Top" 2.3L DOHC VTEC Engine. Celebrated by enthusiasts as one of the best-kept secrets in Honda engine building, the H23A Blue Top combines the high-torque, long-stroke 2.3L displacement of the F-series block with the aggressive high-flow DOHC VTEC cylinder head design. Sourced directly from Japanese-market Accord SiR and Prelude donor vehicles, this engine provides a significant "plug-and-play" torque advantage over standard B-series and H22A swaps, making it the ultimate power plant for any mid-size Honda performance build or track project. Every unit is inspected for internal health to ensure the raw, mid-range punch and reliability that only a factory H23A can deliver.
