I would really like to make my lexus faster. The gs allows for some nice cosmetic work, which i've capitalized on. ( Black wrap on top, halo style Lights, planning to tint windows and add new wheels) but on top of the cosmetics I also want be faster to match the cosmetics. I plan on adding a Cold air intake as well but I really want to know if I can add a Turbo and if so what kind of strain can I expect on the engine?
