[boostedh23a1]

Hey guys i have a 90mm Wilson throttle body which has a 88mm square flange. My intake manifold has a 78mm square flange. Is there anyone that makes an adapter? I dont want to pull off my maniold yet again...
Thanks,

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. 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...



Drove the car today, and this thing is worse that the ebay one. The action is smoother but the return spring is not enough to close the throttle blade. I am going to call wilson and see if they have a stiffer spring, if not im gonna have to put some ugly a** regular springs on the linkage.

Throttle body looks great! It's likely not going to cause you any trouble HP wise at all. I have a Q45 unit and it's a bit touchy, I liked the more linear response of the OEM throttle body.
