The bold text is all you need... for a stock motor.
Do some research, there's plenty VE mods info out there.

Why a bigger throttle body?I think that stock is pretty good for a NA motor.Just run a 100 shot off nitrous.

I have an aftermarket sr20ve header for sale $1500. Guaranteed 10+ HP at the wheels. Thats a sr20ve top mod.
