Configuration: Inline-4 DOHC 16-valve VTEC
Displacement: 2.3L (2258 cc)

The H23A Blue Top combines the larger displacement and strong torque of the H23 platform with a high-flow DOHC VTEC cylinder head. Producing up to approximately 200 PS in its original JDM application, it is an excellent option for performance-oriented Honda builds and H-series engine swaps.
