hi, what are the main differences between the SEH (130bhp 8 valve in sri and carlton) and NE (115bhp 8valve in calibra etc)
i have heard and been told it is all in the head but someone now thinks it is in the pistons and block.
am i correct in thinking it is the valves and ports in the head that pose the difference in power and that the block is the same?
