Installing throtle body

i have a crx si and i have an overbored throthle body i want to install.Last time me and my friend tried installing it the car would bogg out and couldnt make it uphill.We adjusted the idle and everything.So do any of you guys know a site that shows step to step on how to do it?

well sounds as if the throttle cable is not linking up with the TB correctly, and this could possibly be affecting the throttle position sensor, confusing it into thinking it is either wide open or completely shut. i haven't ever installed a TB, but that is just what I have come up with thinking about the problem. if i come across anything i'll let you know.
