Rep Power: 0

I am in the process of building a 1998 Civic LX. I have a Engine and trans from a B18c1 that is currently in a 2 civic ex. I have all suspension, exhaust and engine parts but I pulled the computer they were using to run the B18c1 and it was a p2p not a p72. Should I purchase a P72 ecu to run this motor or will the p2p be sufficient. The motor has a Edelbrock Victor x intake on it along with a bbk 70 mm throttle body. I am looking to boost this motor in the future but for now I want the most power out of it. any suggestion or help would be greatly appreciated
