I have a d16a6 out of a 90 SI CRX. Need a fuel rail, mine is missing. Found one off a 89 DOHC B16 and as far as I can remember think they are the same, since the intake manifolds are made with in the same style. Compared a picture of a SOHC fuel rail from a 91 CRX SI to the picture of the 89 DOHC fuel rail, size for size, and mounting holes look exactly the same , as well as injector hole spacing. I can't tell these two apart!!!!! I just want to double check and see if anyone had any problems doing this with injectors sealing or mounting or anything. Any info on differences would be appreeciated. Thanks!
