Is it possible to swap the standard efi injection unit on a 2.0 DOHCi Sierra for something like a webber carb, what are the pros and cons and also prices for the carbs would be good and thier codes. Also i presume that the carb would be lower than the efi unit under the bonnet.

Is this possible to do or can you infact use throttle bodies?

If either whats better - prices - codes - where best to buy.

Give your honest opinions thanks guys!
