What engine should i swap into my civic?
 

I currently have a 94 civic dx with a d15b7 engine 102hp (that makes me unhappy).































I was hoping to swap my engine for something with a little more kick, im thinkin VTEC.































What would be the best engine that would pretty must bolt right into place of my old one?































Im kinda looking for someone whos had experience swapping the d15b7 engine and knows what is easy.































Anybody know what I should be looking for?
