The F20B is available from 1997-2000. It came in the Accord SiR (Auto) and SiR-T (5-Speed). It is a destroked H22A to make it elegable to race in certian Japenesse racing events where a 2.0L is the highest displacement allowed.
The F20B is pretty hard to get. I do have access to one for sale out of a 2000 SiR with 4700 km on it (2000 miles). PM me if you are intrested and I'll give you the info.
It's got an 11.0 compression ratio and loves to rev high. Why would people want it over the H22A? I don't know to be different? I'm sure there is some real technical reasons out there. I just went with the H22A. I'm not tring to complicate things.
The installation should be just like the installation of any OBD-2 H22A. It does not come with power steering but the block is casted to bolt the P/S pump to it and you would have to change the harmonic balancer to one with a pulley for the P/S pump. The SiR and SiR-T comes with electric assit P/S and the amount of assit can be set by the driver via knob located on the dash. Pretty sweet system. To bad it was never brought here.
