Like many others have said.. the front bumper will have two "vents" on the left and right side for the intercoolers. Like this: Also the engine should have 2 sets of thick hoses on each side, and most have a "twin turbo" badge on the intake manifold, Like this: And then the TWIN TURBO logo on the back, and also the wider wheels on th back. Also, in the engine bay, on the front passenger side wheel well there should be a pump, this is for the HICAS (all wheel steering) that only twin turbos have. Hope that helps. OH yeah, please tell me someone handed you down this car and you didnt buy it?
