You wont see much of anything from a TB...not worth it at all.
I think it's from both.

I've drivin' other gsr motors with larger throttle bodies and regular intakes, and the throttle response was much nicer. Having a bigger throttle body really helps throttle response and I'm sure the J's helps it along also.

I'm pretty sure its a 65mm. I could be wrong but that sounds right. But anyways I personally wouldn't waste your money on a TB. It won't help out that much to be honest. Unless you have a lot of work done to your car where you would need to be sucking in much larger amounts of air. If you do decide to get a TB anyways just make sure you don't get one too big, because that would just hurt your power instead of give you gains.
not that i disagree but im just wondering how does it hurt your power? i always thought the easier flow of air the more power...

if its too big, you'll lose power down low but gain it up high. if its to small, you'll gain down low but lose up high. its a compromise of where you want your power.

it doesnt make sense to me though.... like it only takes a really short amount of time for the throttle body to open right? so how can u lose that much low end?

its all about air flow. the smaller it is, the more air you can get into it at the lower rpm's. but as you go higher and airflow increases, it becomes a restriction and not as air can get in. with a bigger tb, at the low rpm's there wont be as much air coming in, but as you go higher, again, airflow increases and it can take advantage of the bigger opening.

for the less experienced with physics & motors i would like to make snoopys explanation for losing power at the low end simpler (i know from experience that it is really confusing to figure out at first, even when having explained to you)

It seems almost impossible that a motor can lose power with a bigger intake.... like he said, its air velocity, but it is easier to think of as vacum. Just imagine trying to suck water through a regular straw.... then imagine trying to suck the same amount of water through a straw 1 inch in diameter.....it actually takes more work and will probably take more time...unless you have high suction(which comes at higher rpms.)

sorry if this sounds like a lecture, but im sure it will help someone.

You want to keep the air coming in at a high velocity so that it atomizes the fuel, if the air is going too slow (big throttle body) at certain rpms, the fuel wont atomize and it sticks to the sides instead of staying at the center of the airflow.
