Some information on the JDM F22B DOHC engine
you came from: Master List > Engines


All Accords and Preludes in North America were sold only with Single Overhead Cam (SOHC) F-series and Double Overhead Cam (DOHC) H-series engines respectively. Outside North America, DOHC F-series engines were also available.
Wikipedia has more info:

The ready availability in North America of used Japan Domestic Market (JDM) engines means the F22B has become a popular engine swap option. A correspondent of mine who has done this swap on a '93 Prelude has provided the information below.
Warning: I have never myself attempted the use of the parts shown below. I have no way of definitively confirming that the parts listed below are correct for this application. My correspondent seemed to me to be knowledgeable and I had no obvious reason to distrust him, but you must use your own judgement on your own car, and follow this page at your own risk. Always physically compare old parts with the new ones before actually installing the new ones. It would be nice if anyone else who attempts this repair with the parts shown below could send me their thoughts and experiences , if only to confirm the part numbers shown below worked for their engine.

This does not often actually come up the Usenet groups, but I get occasional private emails from people who either have cars that came with F22B's or who have installed one into a car that originally had something else. These people are usually looking for part numbers for the timing belt, balance belt and water pump. North American dealer databases do not readily have those numbers available, at least not such that you can find them using a North American VIN number.

As outlined on the Wiki pages above, there were several DOHC F-series engines available outside North America. The one I encounter most in private emails to me is the F22B, so this page gives the information I have for that engine.

Timing belt
Description: 126RU24 (126 teeth, round tooth profile, 24mm wide)
Honda part number: 14400-PT2-004
Gates part number: T132 (also fits 1988 Dodge Caravan 2.5L)
Duralast and Dayco also make this size belt, but I don't know their part numbers.
(The Honda belt will be about $90. Aftermarket belts will be more like $20.)

Balance shaft belt
Description: 70RU16 (70 teeth, round tooth profile, 16mm wide)
Honda part number 13405-PT0-004 (same as '93 Prelude H23A1)
(Honda belt about $60, aftermarket more like $15.)

Water pump
Same pump as that used on US-market '93 Accord 2.2L SOHC F22A

Tensioners, oil filter, all gaskets and seals
Same as those from US-market '93 Prelude 2.3L DOHC H23A1

Other parts (notes from my correspondent)
Timing cover and crankshalt bolt must be from the JDM F22B (they are different from the H23A1). They are marked "PT2".
The H23A1 knock sensor does not fit into the oil sensor hole on the F22B, so use a brass 1/8 to 1/4 pipe thread adapter ( I got mine off an old auto tranny line fitting) make sure to seal all threads to avoid oil leaks.
 The H23A1 oil sensor has to be swapped over also (hole is plugged in the F22B).
 Don't bother trying to swap the water lines for the oil cooler; it's not worth it.
