The 55mm butterfly clears the smaller 46mm bore because it's round and high enough so that the edges don't touch. Did you need to remove the stock o ring gasket? The 1ZZ will definitely give you a quicker throttle.

I have the 1zz tb as well on my 2007. High idle at startup when cold is common, verified with the scan gauge. Congrats on the successful install. My mechanic did mine in under 30 minutes. A worthwhile mod!
