From WIKIMOTORS: Toyota 1ZZ engine tuning 1ZZ-FE Supercharger
You will have to buy such performance parts as a Toyota SC14 supercharger, intercooler, blow-off, cold air intake, 440 cc injectors, Walbro 255 lph fuel pump, ECU Greddy E-manage Ultimate. Having adjusted all those performance mods, you will get about 200 horsepower.
As you see, it gets even more expensive. You could probably do a conversion to a 2ZZ for the same price.
