Recently purchased a 1994 2.0 16v Ecotec Astra Gsi. Just how much BHP have I got. Some say 150 some say 136. I'm confused.
I know the red top engine had 150 and the Ecotec is a very similar unit, so why does everyone slag off the Ecotec but kiss the arse of the red top engine. (PS mine is full of flat spots)
