I own a '93 SI and recently the engine blew up thanx to the famous ticking sound. It didn't last one bit. Well I was doing some research and found three engines that I think and read would work great on my car. The first one is a B16A, the second one B18c and the third one is a F20b. I'm planning on building an "all motor" engnie and the choice is between the b18c and the f20b. I'm new to all of this swap thing so any help you can give me would be appreciated. I live in Puerto Rico and there are a lot of b18's but a lot of f20's and that's something to consider.
