Cynos S would be the 5efhe if it came from that car
i've had a 5efhe from a sera which came with the same style "4efte" intake manifold
i've had another 5efhe which came with the ACIS 5efhe manifold
both had 5efhe rods and pistons and were basically identical other wise...apart from the intake manifold
