physically they bolt up the same, but the pressures are different. you need a vtec pump with a vtec head/motor

all B series pumps will bolt on. for LS/b20 vtec you need any VTEC oil pump, GSR, TYPE R, B16 JDM b16 JDM GSR... etc...

i think the obd2 one is a bit different cuz it uses a crank sensor, not sure if it's usable on obd1 block or not i imagine the bolt holes all line up
