I'm in the process of buying a 1991 Civic EF Si model.

It comes with a JDM ZC engine but that is not enough power for me. (my daily driver is a NOS powered Benz)

newayz I hear of crazy swaps here and there so can I replace the block w/ B20 or B18? Or does it require a lot of other parts such as boring it out, cylinder stuff, blah blah.

I know it has 130 hp and 130 torque.

I'm also putting cold air intake, NOS, headers, and exhaust on it. I got my carbon fiber hood, and rims waiting

If I can't increase the displacement, I guess I'm going turbo. I wanted to turbo after increasing the displacement though. Any help would be appreciated! Thanks in advance.
