Boring throttle body???
#2
A bored throttle body does give you a little more HP but I don't think there is any way you can do it yourself since you also need a larger butterflu to close it off and it must seal compleetly. LC Engineering has them but the cost 2-$300.

I did this on my 5VZ. Same idea. Just taper it like I did.
