ok i dropped a 1995 ls motor into a hatch about a week ago and its not running right and i cant figure out whats wrong with it. the car starts and drives but has NO power at all, when it idles it seems to be fine but when i rev it up it sound like its choking or something i think its running really rich, the compression is around 150psi in all 4 cylinders, the motor and everything is from a 1995 integra but the head is from a 1992 could that be the problem? I've changed the fuel pump, injectors, fuel filter, map sensor, distributor, spark plugs and wires, anybody has an idea what could be wrong?

what ecu are u running with it? did it come with the motor or the one that was in ur car? and what year is the hatch?
