The car was never driven w/o the dump tube.... The turbo Is brandnew along with the Revhard manifold....just took a few pics to help a few people having issues installing manifold. Though it would be great to have an AEM not necessary unless trying to make 600hp which I'm not trying to...Car is just fun for street or Highway Use.... To make the car complete it need a stand alone, SMIM, Cams, valves,springs,retainer and a meth kit....
