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.

 

if you just swapped everything from the b16 into a b18 block youre not going to see anything from it? Mabe I dont quite understand the question.

 

The question is, is it possible to use just the B18 (LS) block and the B16 Civic SI head (VTEC) in a 1999/2000 Civic SI (LS/VTEC Swap.).

Or would it be better to keep the engine the same?

 

what are your future plans for the motor/car? If its a daily driver you might consider keeping a stock head/block combination. If youre going to be doing some work on it then ls/vtec combinations are making decent numbers from what ive seen. No personal experience with ls/vtec but certainly worth considering sepending on the direction youre looking to go.

 

i thought a b18c1 was better than a b16a. i also thought a ls/vtec was better then a b18c1, if built correctly!

 

B18c's are better than b16's. ls tecs have more horse and a lot more torque than a stock b18b or b16a.

 

maybe a b20 block?? 2.0
