Hi Michel interesting about ls2 but i dont think i have seen one at that price yet about 6500 is what i have seen them for sale at but with only extractors and a 2 and a half inch exhaust cold air intake and maffless tune a work college here in Perth has recorded 363.4 hp at the rear wheels @ 40 deg at Pro Auto and that is with ve 6ltr L98 not bigger vavle ls2 same mods on ls3 6.2ltr hsv is just over 400hp at wheels
