The bad ass extension used to get the bolts on the back-side underneath the manifold. This wasn't as bad as I thought it was going to be. However, there were a few points where we wanted to just quit. Quick question - I couldn't use the factory throttle body spring that the pulley compresses, so I used one from a 97 civic LX. DAMN - the thing feels like it has fly-by wire or something from an S2000. The throttle is VERY sensitive and sometimes sticks. I am going to either buy a B16 spring from a junk yard or a complete throttle body to replace the GSR one. Other than that, I have no CELS, no "check engine" light either. Any questions/comments just ask.
