on the head, it says what year it is....my car is a 92 and it has 92 stamped on it. and about mileage, they really cant tell unless its a front clip with the gauge cluster.

if the motor is obd2 you get the ecu from that motor and it WILL plug into your harness, but you will need the vtec wire harness and wire that up. someone correct me if im wrong im not 100% on my last statement..

your intake will fit and the radiator should be fine too.....depends on what your doing with the car, ie, daily, racing, autox.
