The motor is a f22a1 from a 90 accord. The intake manifold is from a h23 engine. I have the intake manifold with the butterflies, thermostat, butterflies, and throttle body. Can any body give me (or tell me where to find, because I have looked) a step by step to installing this IM. I would like for the butterflies to work for gass mileage reasons. If you live anywhere near Vass, NC let me know and maybe we can work something out where as I will pay you to install this for me. As usual Thanks!!!
