I have a d16a6 right now in my 88 crx si. I bought two y8's that came with intake mani and throttle bodies. I am swapping the vtec head onto my a6 and was wondering, is there any benefit to swapping on the y8 intake. If it gives me one horspower i dont care, it isnt worth the time, but just want to know. I am going to run a .42/.48 t3 snail on it once it is together. I have heard (i think) that a b-series throttle body will bolt onto the y8 mani. I am just trying to figure out why some have done it. If i put on a B-series throttle body that is port matched, will it even be noticeable? Sorry for all the noob questions, just starting my first car build and wanting to do it right. (I am a D-series lover for now because of $ and dont want to be a bandwagon jumper) Thanks everyone for helpin me out. I have just made the move from hater tech aka honda-tech. i am hoping i dont get flamed here like i prob would on there. Also, sorry about the title, probably confusing.
