you can get all of the parts i mentioned in my post second hand on here, in fact its what iv done, i modify all my cars, its my hobby. makes me laugh everyone posting figures they got on rr's, everyone on here goes on about how inaccurate theyare, how if your car makes 170 standard the rr is wrong and isnt calibrated, then if its too low its because "they all run about that as standard" but hey look at my graph after my rs2 was fitted, must be right. drives so much nicer, pulls all the way through the rev range etc etc. anyone heard of placebo affect?? everyone is entitled to spend their money how they want of course, just that IMO i would pick up a second hand set of throttle bodies and ecu for £1500 instead, which also come up for sale now and again on here and ebay etc. the end.
