gsr's are out there, but the insurance is cheaper on ls, my ls is blue booking around 6-8000.00 stock with high mileage, no idea what i could get for it with mods. as far as turbo pricing i'm not real sure of, aprox. 2-3000.00 for the kits i've spec'ed, like my ls but i would go gsr if possible http://ouw1sh.com/php/modules.php?op...orderby=titleA
