JDM 1998–2002 Honda Accord SiR / 1997–2001 Prelude H23A 2.3L DOHC VTEC Engine — Engine Only — Approx. 59,000 Miles
Genuine Japanese-domestic-market H23A 2.3L DOHC VTEC inline-four, imported directly from Japan by JDM Alliance. The JDM H23A is the DOHC VTEC version fitted to the Accord SiR — a different, higher-output head from the non-VTEC H23A1 sold in the United States, which is why it's bought as an upgrade rather than a like-for-like swap. Serial H23A-2004877.

What's included
Please note: the transmission is not included. Although parts of it appear in some photos, it is not part of this listing. You'll re-use your original intake manifold, exhaust manifold, ECU, wiring harness and accessories. Anything else visible in the photos is included unless noted otherwise.
Fitment
Depending on your application this may install as a long block with your original external accessories transferred over. Running the VTEC head correctly requires compatible engine management. Confirm fitment with your mechanic before ordering — call or text us and we'll help you check.
Warranty & returns
This is a performance engine — an upgrade over the engine it replaces in most applications — and it carries our 30-day performance-engine warranty and a 30-day return window, not the 90-day start-up warranty that applies to like-for-like replacement engines.
