One of my friends has a 92-95 civic h/b with a D15 in it. I have a D15B2 from an 88-91 civic h/b. Will the B2 just drop right into his h/b? I know some of the sensors would have to be swapped and the dizzy too. His D15 that he has now has a burnt valve and the D15B2 that I have is in good condition with only 100K on it.
