i have a 3i shell because the guy said the rs shell was fooked so used a 3i shell and from what ive been told the logbook will say 3i derived rs turbo (i think) the exhaust hanger is missing on a 3i (between the rear arms) under the rear bumper the shell is cut out on an rs were the spare wheel sits (basically remove bumper and youd see more of the wheel well on an rs ?) rs turbos have a rear roll bar but the 3i doesnt ?
