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.
