300WHP is about the limit that you want on a stock 2AZ-FE for a "Regular" daily driver. ....There are a lot of "Daily" drivers that go, what, less than 5 miles a day..... Anything over 250WHP is plenty in a tC, 5-speed. With this amount of power, you should be moving well over 200ftlbs of torque. What you need at this point is to put that power down to the road. Think about stiffer springs, wider rims, sticker tires, limited slip differential, stiffer mounts/engine stabilizer. If not 300WHP will have you handicapped to a 30 roll
Ahriman is correct, 300WHP takes more than just a S/C or turbo. It takes supporting mods like larger fuel injectors, exhaust, intake, fuel/ignition control, professional tuning. The S/C alone can't make 300WHP w/o the additional help of some sort of intercooling with a water/meth system being most preferable. Most of all, it is the tuning with a piggyback or a standalone that is going to make your tC outlast those Hondas/Nissans.
BTW.... You came to the right forum
