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

 

use you old b18 intake mani on the b20. same bolt pattern and the hoses will be the same.

 

yeah b18 mani b18 dizzy and the b18injectors and you should be good to go, but the only question i have is how did he get a 93 crv motor the first year for crv was 96?
