Awesome engine, I love mine... Since your OBD1 already nothing to worry about as wiring goes... u may have to swap over O2 sensors (the one that comes on the D15B is single wire, the one on the OBD1 setups is 4 wires, except the VX which is 5)...

Yes your tranny will bolt right up... Just remember if u buy a new clutch, flywheel, ect, u will need the one from the original tranny... So if u have an 88 CRX Si, and thats the tranny that u used, buy for that car...
