hard choice on import

I blew a rod in my 96 civic. I want to swap it with a different motor. I was looking at the 2002 RSX K20 motor, the 97 prelude H22, and the B16A2. People say the easiest is going to be the B16, but i think the other 2 are going to be faster. The K20 is a 6speed but they say intalling the wiring harness is going to be really tough and labor is going to be expensive. They also say the H22 has a cable shift linkage intead of a rod like on my stock civic, hence it will be more of slow shifting but then again they say this motor is a beast, and so is the K20. All i hear about the B16 is its easy to mount and great for future turbos. I want speed and more speed, i dont wanna pay for intall, just wanted to do it myself but the k20 seems intimidating because the tranny is on the left unlike my stock tranny on the right. Please I need as much advice as possible. One more thing, can i use my stock D16Y7 tranny for the B16 incase i decide to go with that?
