even if u dont have to i really recommend changing the engine mounts, just to be safe.. when u got vtec engine likes to punch itself around lol

I think he means just a drop in swap, no VTEC.
changing mounts is a good idea, particularly the rear. Also do things like water pump and timing belt etc. wiring should be pretty simple depending on how the B18B was put in

Well swap your dizzy and intake manifold to the B20B8 and you should be fine. There might be a knocksensor on the B20B8 you will have to disable.

It all depends on how the b18b was installed. Chances are, you're in luck since the b18b will already have the fan switch, thermo housing and other bits already modified from the B18A. It will most likely be a straight swap. If it's still running the stock ecu, you wont be able to use the b20 injectors.
