I just picked up a 2000 Civic Si a couple months ago and I was wondering what everyone thought about a B20 swap? I saw that complete B20's are pretty cheap and I looked at doing all motor builds for the B16 in it, but we all know money is tight especially being in college. So would the B20 give me a decent bump in power for the money? Also, what VTEC head should I use on it? I see that the B18 head is the most popular, but will the head from my B16 work?
Will the tranny from my engine bolt up to the B20 block since it's a B series motor?

I appreciate any input on this, I'm definitely interested in trying out this swap to do something a little different than what most people do around where I live.
