hi all new to the omega front and just brought a 2.0 16v ecotec omega on a 2000 w reg , i had a 2.0 16v cavalier ecotec before with ported head , cams etc and have swapped it all over to the the omega  , now i had a lightened flywheel on the cav and was wondering if it will fit the omega being that its rear wheel drive ? . also does anyone know if there is a lexmaul manifold for the omega ? as the cav one didnt fit obviously lol. any help on what i can do to this car would be of great help

would like to do away with the 2.0 16v engine but being 21 with no no claims is holding me back for a few years
