One easy thing to do is check the track of the car (the distance between the rear wheels). If it is the same as the Turbo I bet you have a good chance that bumpers will interchange. If not, IMO, forgetabout it.

Also, guys are always saying the aerodymanics of the car will be disturbed when you mix and match "aero kit" parts like that; but I'm still not sure if that's a big deal at speeds slower than 130mph.
