sup pplz...i have a g2 integra and im wondering if getting a b20 motor(just da motor) would be plug and play. what i mean is is it just:
1. unplugg all the wiring on the b18
2. take out the b18
3. swap in the b20
4. plugg all the wiring.

are these the only main steps i need to do if im only swapping in a motor with bigger displacement? and do i need ecu from a crv? please tell me what are all the other important things i need to do. i figured since its a b series and its non vtec i wont need anything in particular. but yeah help please.

 

i would tell you to search...but being that i'm hella tired and don't feel like being somewhat of a *****...here's what you'll need to do.

being that most of the sensors are on the intake manifold and throttle body, just swap your original intake manifold on to the B20. and that should be about it. you don't want to use the crv ecu because it's usually an automatic ecu. just stick with your ecu and get something to tune it like an AFC.
