i have a 91 civic that i have taken the d-15 engine out of to place a b-18 non v-tec engine in. but i am faced with a problem i dont know what is compatable with the motor. i wanted to throw a 1.6 v-tec head on it with controller and take the injectors and throttle body from the 1.8 and put it on the 1.6 head. will this work? please help because i am going with the whole more air and fuel means more HP theory.

 

first of all thats a big project and involves a lot of tuning or it will never run right and you will burn oil like crazy and it willl just piss you off if tuned improperly. yes it will work. you will have to do a lot of research before you get that deep into something. all b series motors and transmission are compatable with with each other. same with d series for the most part. if this is the route you want to take i suggest you do a lot research.
