ur gt is the coupe version it has a 5sfe 2.2l dohc with 130hp and 140 lbs. of torque. ur best bet if you have plenty of time and money and good knowlege of engines or a good mechanic is a 3sgte swap. it is a turbocahrged 2.0l with 200hp for u.s. versions and 225hp for the jdm version. you can turbo ur 5sfe but you cant run high boost and the 3sgte has more potential. poweredbytoyota.com has a 2500 dollar kit for sale ior you could build your own using parts from a 3sgte. if your new to cars and dont have alot of money yuou can do ur basic intake headers and exaust mods and have about 150 hp.
