I just had 205 nozzles installed. It's no rocket ship, but it performs as I would have liked from the get-go. I bought my 02 Golf GL 5 spd used ($12K) to save on fuel costs over my Big Block Chevy muscle car...which btw is a rocket ship. Depending on your goals, 205's are a moderate bump in performance without having to upgrade the clutch and killing the mileage to much (I hope).
