    ive heard that if u swap out the b18a intake manifold and throttle body with the b18b manifold and TB..it will give u like 5 or 6 hp to the flywheel...and i know thats not gonna make a difference..but tommorow im adjusting my valves,settin my timing,changing my oil,so i figure i should swap out the IM and TB since i have a spare motor in my garage...

    Question : does the head have to be removed to remove the intake manifold while its in a car?? ive heard people say it does and it doesnt...im trying to do this the easiest way possible.

    another question : the injectors on the b18b are obd1 correct...well my b18a is technically obd1 cus it came out of a 92 integra...if i swapped everything over (fuel rail,vaccuum lines,TB with map sensor on it) would i run into the OBD problem?
