Did 1st Gen and 2nd Gen 4G63 engines come as 85mm Bore and 88mm Stroke?
I need someone who knows the answer. It seems if the rods fit all then the bores would be the same since the displacement is.

Yeahup you are correct, the usual eclipse/talon;1g/2g 2.3L stroker kit is going to 102mm stroke (88mm stock) and 86mm bore (85mm stock). Though I am not sure if this is what AMS is using for the Evo, but most likely they are. Hope this helps.
