I have a renix motor, so my TB doesnt enck down like the new HO stuff. I was planning on boring my TB out to the 58mm, or maybe 60 like the HO's. What do you guys reccomend to bore it with?
 
A boring bar. I assume you have a Bridgeport or reasonable facsimile?
 
use a drill press and a 60 or 62 mm drum bore to do it. once u do it ull want to round off the edges around the holes inside the barrel, and use some extremely find grit paper by hand to smooth things out

XJ Armor sells just the butterfly valve, for you DIY borers.
