the b series engines that came in that lude aren't the same as the b20 found in the crv.

B21A engine that was only produced for the SiStates which was only found in JAPAN.

You'll most likely have B20A3 Honda Prelude 2.0 S 1990-1991

B20A3

(12-valve, SOHC, dual side-draft carburetors)

* Found in: o 1988-1991 Honda Prelude 2.0 S
* HorsePower: 109 @ 5800 (MT)With cata 115 @ 5800 without cata
* Torque: 111 @ 4000

However you said it has fuel injection

B20A5

(16-valve, DOHC, PGM-FI)

* Found in:
o 1988-1989 Honda Prelude 2.0Si
* Power: 135 hp
* Engine cc: 1958.14
* Cylinder cc: 489.535
* Deck cc: 13.885
* Head cc: 47.3
* Compression Ratio: 9.0:1

engine using a pk-2 honda ECU based on oki83c154 processor (intel 8051 based with external ROM)

is there even aftermarket support for that run of b series engines?

IMO save your $800 and put it towards a B16 instead.
