How do u know its the 3 stage VTEC version? The 92-95s arent 3 stage... Does it have 2 VTEC solenoids? If it is indeed the 3 stage, then you will need the proper ECU which would be OBD2, otherwise you will not have 3 stages of VTEC... The P08 is the OBD1 version for regular VTEC...
I looked it up and found that the ECU is a: 37820-P2J-003 (manual) or 37820-p2j-j61 (mulitmatic)... Good luck with the OBD2 conversion tho...
You can probably run it OBD1 with a P08 or P28, but you wont have 3 stage VTEC...
For a write up on the regular 2 stage D15B VTEC into a CRX look here:
