cheap...ish mods?
Im looking to improve the performance of my rebuilt 1990 1.4 vauxhall astra mk 2, It has a non standard exhaust, twin webber carbs and a k&n buscuit tin air filter, I recently changed the plugs and I am considering getting a new flywheel perhaps but Im not sure how much it will cost or what else I can do other than going to the expense of buying a turbo or 2 litre red top engine? Any ideas?
