So I went and bought a d16y8 manifold to throw onto my d16y7 and the guy also gave me a fuel rail and the throttle body with it. Will I be able to use the new fuel rail and throttle body or am I going to have to just use my d16y7 stuff? I googled around, couldn't really find much about this. I don't have the money for a new ecu or anything that's why I'm asking. Can I use it on the stock ecu? and SHOULD I?
