^^^ what he said. To gain HP, you need to "unrestrict" the airflow in and out of the engine, cold air intake = denser air, more O2 to help burn the gas. I've heard the stock intake manifold is good for 350-400 hp quoted from toyota engineers so I don't think I need to replace that, port match probably tho. Less restrictive exhaust manifold, pipe and cats will help as well. Then there's the expensive stuff, like the port match of anything the head touches, intake, cylinders, exhaust, and polish, shaving the head, ARP stud kit, MHG, overbore .020 or .040, increase compression to around 10 to 1... run GOOD gas..
