im helping a friend do a swap from a b18a to a b20 out of a 93 crv. i am having trouble with the vacuum system and was wandering if any1 had those diagrams to both those engines. the car im doing the swap is a 1990 acura integra b18a original. he got gunhoe without doing the reseach and bought the b20 and now im trying to make it work. i do apoligize about this being in the wrong forum just hoping to get faster results. thanks
