could you swap the throttle body back over to the other side where it was from factory? I have plans to do a 6G75 MIVEC swap into a Diamante wagon with the same 6G72 SOHC 12V originally yours had. I plan to cut the perimeter of the plenum and rotate it 180deg and weld it back on so everything is reversed sides. I also plan on cutting the throttlebody flange and reattaching so it's the same angle and approximate placement as the original throttle body so I can use the original intake pipe to keep things looking somewhat factory. The EGR tract is going to be removed and hole welded up etc and sanded smooth so you'll hardly know it was there. The head to upper manifold mounting nubs will also have to be cut and rewelded if they were to be retained. I figured it would just be easier for us 3000GT/Diamante platform owners to retain the throttlebody on the original side.
