Ok Iam trying to figure out whick dohc d16 motors are swapable for the 88-91 civic si. I know the first gen teg motor you cant cause of the motor mount isent in the right location, So what DOHC d16 motor will be swapable into an ef civic si for ease of instilation? A zc has crossed my mind but the fact that its takes like 6 or so motors to make that one makes me nervious and I dont want to carry a list. Basically is the d16a8/9 the easyest swap? or whats your oppinion cause I dont want a b k h or whatever. I want something out of the norm and SOHC is not what I want.
