I got for sale is a modified 2zz intake manifold specially cut and fitted for a celica GT 1zz. You will feel more pull at higher RPMs and great setup for turbo or nitrous because you replace the plactic manifold with this aluminum powder coated manifold. I dont know how much HP it gives you but you do pull away from any 1zz that is N/A w/o this setup. This also comes with a new gasket for a 2000 corolla that fits and two 2zz throttle bodys (DBW and DBC). I am asking for $300 w/o shipping. I got paypal let me know.
