Just wondering, I know that the 1999 and 2000 civis SI comes with a B16 engine, not sure on the exact code, but it has the DOHC VTEC. Okay, so, I've heard and read about the LS/VTEC Swap people usually do for integras. Now, I was curious, since I do plan on getting a 2000 Civic SI, if I were to take a LS/B18 Block, what problems would I have replacing my regular block?

I know the B series parts are interchangeable, but would I run into needing to replace anything else? What year blocks would fit?

Sorry if this has been posted before, but the only things I could find on a similar swap were going into integras. I didn't know if there wouldn't be a difference or not.
