definately dont get the ecotec lump mate, only 130 bhp from a 16v lump!the cav gsi lump is an earlier redtop, with nearer to 160bhp, much more potent. the ecotec is a restricted version of the redtop, restricted so as to meet the eu emission regulations at the time.
get the redtop!

Maybe im bein stupid!!!

1. CATALYTIC CONVERTER

2. ANGLE OF THE VALVES

....But there are a lot more lower mileage ecotec engines around
than Red Top valver engines, plus they're cheaper.
