the only difference between the c20seh and c20ne engine is the cams, pistons, and ecu. correct?
everything else is the same, head, bottom end, manifold etc.
so in theory, if i were to put seh cams pistons and ecu on my ne, it should run c20seh spec (it wont as its down on power anyway).
and could i fit a rebuilt top end (head etc) from a seh to my ne?
