We are swapping in a 95 JDM SiR motor in my friends 94 Canadian Si. We wired it up and have one problem. The new motor does not have a thottle body mount MAP sensor. he old motor (D16Z6) has some sort of vacuum sensor on the right hand side of the intake mani also. I'm an OBD0 guy myself so what is this vacuum sensor on the back of the manifold and what do we do for a MAP sensor. Can we use an older generation firewall mounted, Use the old throttle body, and what do we o about my mystery sensor?
