Tebb-From what I've heard, the Supra TT manifold will not fit in the IS because of the ABS system. But, there are turbo kits out for the IS. One is Toyomoto and the other is XS Engineering. Those are custom single turbo kits(expensive). But, if someone knows how to hook up the Supra TT system than plz lemme know also..Hope this helps.
