Purchase my XR5 Turbo in November 2010. First mod was a Pro Alloy ST/RS intercooler and was followed by several CAI's before settling on the Mountune MR 290 tune. I swapped my DS CAI for a stock air box and then installed a pro alloy big boost pipe kit as well as Blue Flame Turbo back exhaust and next posted computer to Mountune for upgrade. Car went very well once computer back. Next mod was a top pipe from air box to turbo which was made here in Australia, it's a 3" stainless steel jobbie that is ceramic coated to help keep the heat down on the air to the turbo. This pipe has made the tune very smooth and responsive. Also performance filter in stock air box. Next was a Elevate 25.4 mm rear bar with whiteline lateral locks. Rennsport racing rear camber arms, front whiteline 24 mm bar with lateral locks and polyurethane control arm bushes. Next mod was the Mountune Clubsport suspension struts,shocks and springs along with there alignment set up. Love this little car and now handles and go's the way i want while looking stock on the outside.
