I have a 94 Integra and the motor went bad. I found a B20 motor at a pretty good price and I need to know if it's completely drop in compatible or do I have to change a few things in order for it to work. I was thinking the ECU,and Tranny might be a problem. Let me know ASAP! I need to decide what direction I should take. Thanks alot!

Just the ECU. B-B all works out.
