I'm new to all of this. I have a 90 hatch with a B18A1 in it and I want to do a B20 swap. Just wondering what can I use from B18 setup and what I can't. I just got car and don't know too much about it besides it's a stock B18 from a 90 Integra. Not sure if I can use same ecu or not. Battery is in the way for any kind of intake so I need to relocate that. I'm a newbie so bear with my lack of info and knowledge.
