Well, I ordered a Wilson 90mm throttle body. I sent it back and went with a 80mm. The action on both of them are sweet, much nicer than the one I have on there now. I am replacing it because it is sticking at idle and sticking at WOT... not good. I got a new lokar throttle cable and will post that write up as time goes. Anyway the Wilson flange is 88mm square flange and the flange i have on there now is 78mm square flange. I put the throttle body in the mill and elongated the holes to fit, sounds easier than it was but its done now. I also had to tap the TPS bolt holes on the 80mm which was odd because the 90mm came tapped already (4mmX.70). Anyway that is also done now. Hopefully I will get some time tomorrow to bolt it on. In the meantime here are some pics. 80mm is the smallest thing on my car, all the piping is 3" (90mm) but I dont want an on/off switch for a throttle body. Hope I did right...
