Hey guys.. I tried searching and didnt come up with much. I know that ka/sr injectors are compatible.. So are the injector orings compatible as well? Does anyone have any part numbers? Im putting new injectors into my s14 SR, and I was curious.. Should I replace the insulators? Are there top and bottom ones like on the KA? Does anyone have any tips for replacing the injectors on the S14.. Such as not having to remove the intake manifold? I can take off just the top part of the intake manifold..but is there a gasket between the upper and lower portions? When I looked it seemed to be Nissan goop shit... is this right? Im a fuel system

. Help me out
