Im wondering if a bigger throttle body would benefit my setup. I would like to get to the 350-360 range for hp, but dont want to spend 400 dollars for 5 rwhp. Could i get 10-15 out of one? Also do i need bigger injectors, mine are stock?

Stock injectors are fine for your setup, and personally I wouldn't spend the money on a throttle body just yet.

u don't NEED a bigger throttle body until you get a ported intake, head work, and a cam. i've seen hotcam cars on stock heads get like 4rwhp from them. if you must get a bigger tb, have a machine shop bore out the holes in the stock ones, and make new circle plates to fit the bigger hole. not worth 400 bucks for a new one imo.

i agree when and if you get your heads done step up to 58mm tb and port the intake yourself to accommodate the 58mmtb. brent franker has an awesome write up on how to do it with the intake still on the car.
