Jozinobi Posted April 10, 2007 Share Posted April 10, 2007 I would agree with you Geo on those standard bore sizes.1.75 for n/a2" for turboI've upgraded to 2"on my beast and the next standard size down is 1.75" so the n/a has to be that.Turbo people usually upgrade to 2.25" or 2.5" so I reckon it safe to say oem size is 2" .Joz Quote Link to post Share on other sites
