??? B21A1 ??? HELP
http://en.wikipedia.org/wiki/Honda_B20A_engine
The B21A1 was basically a re-worked B20A5 with an increase in bore to 83mm. The external block dimensions had to stay identical to the B20A5 block so Honda called upon Saffil to create a thin but strong cylinder liner called FRM (Fiber Reinforced Metal) which basically consisted of a carbon fiber matrix, aluminum alloy, and aluminum oxide to make a very strong cylinder sleeve. These sleeves are so strong that they often do not lose their factory cross-hatching marks after 200,000 miles! A lot of B21A1 engines burn oil and have low cylinder compression numbers because the FRM material is so strong that is tears up piston rings. Good news though, you can usually replace the piston rings without any honing to the sleeves and go another 100,000+ miles without any sleeve wear.
B21a
* All B20a and B21a engines are Non-VTEC
B21A
(16-valve, DOHC, PGM-FI)
* Found in:
o 1990-1991 Honda Prelude Si States
* Very rare, it was only produced for the "Si States" models in Japan
* Power: 147 hp
B21A1
(16-valve, DOHC, PGM-FI)
* Found in:
o 1990-1991 Honda Prelude Si
* Power: 140 hp
Will it fit?? Dont know for sure, as it seems to be a sister engine to the B20 then it might just fit. You will have to looking it to the correct motor mounts, and be wiling to do some of your own fab work.

Really all I did was google honda B21A. All this info came from the second or third link on the search. I posted the link to the site I got it all from, it seems like they have a lot of general info of engines
