JDM 1997–2001 Honda Prelude Type SH H22A 2.2L DOHC VTEC Engine & 5-Speed LSD Transmission with ATTS — Approx. 60,000 Miles
Genuine Japanese-domestic-market H22A 2.2L DOHC VTEC inline-four from a Prelude Type SH, imported directly from Japan by JDM Alliance and supplied with its 5-speed LSD manual transmission, ATTS unit, ECU and shifter cable. Serial H22A-4020119.
What ATTS is
The Active Torque Transfer System is the Type SH's torque-vectoring front differential — it shifts drive between the front wheels through a corner to reduce understeer. It was fitted only to the Type SH, and it is the reason this package is worth more than a standard H22A and gearbox. It also means the assembly is more complex to install and service than a conventional LSD.

What's included
Anything else visible in the photos is included unless noted otherwise.
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
Running ATTS correctly requires its own control unit and wiring. Depending on your application this may install as a long block with your original external accessories transferred over. Confirm fitment and supporting parts 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.
