JDM 97-01 Honda Prelude SiR S-Spec H22A 2.2L DOHC VTEC Engine + 5 Spd M2Z4 LSD Transmission & ECU

JDM 1997–2001 Honda Prelude SiR S-Spec H22A 2.2L DOHC VTEC Engine, ECU & 5-Speed M2Z4 LSD Transmission — Approx. 61,000 Miles

Genuine Japanese-domestic-market H22A 2.2L DOHC VTEC inline-four from a Prelude SiR S-Spec, imported directly from Japan by JDM Alliance and supplied as a complete swap package — engine, ECU and the M2Z4 5-speed manual transmission with factory limited-slip differential. Serial H22A-1280176.

Why the S-Spec matters
SiR S-Spec was the sharper of the JDM Prelude grades — it came with the factory M2Z4 limited-slip gearbox rather than an open differential. On a front-drive car making this much power, an LSD is the difference between putting the power down out of a corner and spinning an inside wheel. It's the reason a package like this is worth substantially more than an H22A and a standard gearbox bought separately, and finding the two matched is the hard part.

What you'll receive
We stock multiple examples of most engines, and the unit photographed is one of them. If this particular engine has sold we'll match you to another in the same condition and mileage range. Before anything ships we send you photographs and the serial number of the actual engine you're getting — you approve it first.

Fitment
Engine, gearbox and ECU together — substantially more complete than a bare engine and the practical starting point for a build. Depending on your application the engine may install as a long block with your original external accessories transferred over. Confirm fitment with your mechanic before ordering — call or text us and we'll help you check.

Warranty & returns
The engine is a performance engine — an upgrade over the engine it replaces in most applications — and carries our 30-day performance-engine warranty and a 30-day return window. The included transmission carries our 30-day transmission warranty. Full terms at jdm-online.com/pages/warranty.
