I want to buy a engine from a integra but the guy says its a b16. I thought integras only had b18s.

 

post a pic of it, well tell you. or, look on the left side of the engine block, by the tranny. there should be an engine identification stamp. if it says dohc vtec on the valve cover, then it should say b16a1 or a2, or b18c1 or b18c. any of these engines would give you atleast 20 hp over your engine, assuming you have an LS.
