the OEM TB are 60mm
mine were bored to 62.5mm
62.5mm to inch = 2.46063''
on the posted picture with those shiny polished TB ,, I doubt there was any boring at all since there is still that OEM bump at the butterfly plate
then next ... I hope those 2 screw holding the plate are atleast torqued down with some Red Loctite !!
stacking them is always a safe bet for this stuff !!
the reason why I'm saying this is because the plate is now thinner and not much thread holding those screws...
the work on the lower intake manifold look quite good on those picture
He seem to also have done alright with the matching of both lower & upper manifold ,, could have been better since I think the lower corner were done a bit fast...
