CArbs has been used in the Europe to fit the 40 & 45 webers. U need to remove the FI system & get the manifold for the carbs.
Power will increase but FC will also increase quite substantially. Best way is to turbo the car. If not chuck the engine & plonk in a M50B30 or a S50B30. Really depends on how much you willing to spend & what is your target.
