Follow the end to the air intake tube. When you reach right before the intake manifold, remove that end of the air intake tube and that's where it should be. At least that's how it is on most cars.

What do you mean? Maybe if I had a turbo, but on my 2.4 it's at the end of the intake tube. Not the part with the air filter obviously. Or are you talking to the person posting this thread???

"Something wrong with yours..." does not help figure out who you are talking to. Are you telling me I'm wrong???

If you said "Something wrong with yours?" Then I would know you are talking to the original poster. lol

Did you replace it with DDMs larger diameter TB? I want one of those.

Not at all, I am just looking to port and polish it. I heard that polishing your throttle body will give you a few horse power as well as better throttle response.

The intake tube that comes from my cold air intake just leads to my turbo i believe. I am still having trouble determining the location of the throttle body because the air intake leads to a turbine wheel instead of the throttle body.

Like I said, DDM Works sells an after market TB which is basically a 20% larger than stock throttle body. That's the same as porting and polishing the stock one out more. Might as well just buy a larger one instead of doing it yourself. Gains are only going to be about 3hp at the most. Better airflow is what your really getting out of it. Then again, does it really matter if your intake manifold insides don't match the same diameter? Think about it. You would have to have the intake manifold bored out to match it in order to truly utilize the larger TB. Without the intake manifold matching the TB your just going to get what we call the Bottle Nose effect.

No increase in power from this on a GXP.

Must admit that the location of the TB on the GXP, quite low on the driver side, is a bit ...odd?

Im porting and polishing my intake manifold tommorow, and I found the tb.

(It said my post was too short so I'll elaborate. Bigger throttle body on a stock LNF won't get you anything except maybe touchy throttle response. On a modified motor, WITH A PROPER TUNE to work with the larger TB, AND a modified intake manifold, you will see a power and throttle response benefit.)

Certainly, but these guys are talking about bolting it on a stock engine, in which case my brief assessment covers it - no power boost. Just like the so called cold air intake.

I wonder how much else you'd have to do to the engine and tune to make the stock TB a bottleneck? Perhaps use a larger turbo?

Yeah Bill, it would take a bigger turbo and/or ported head, valve springs, intercooler, exhaust, etc, etc, to make putting a bigger throttle body on an LNF a good idea. Otherwise you'd probably do more harm than good. Hey, weren't we talking about the "bigger is better" mentality on another thread or forum?! It's hard to get guys over that idea. I know you get it.

Devinslawsby, I don't know how to say this without being mean, but if you're having a hard time finding the throttle body, please, PLEASE, don't mess with trying to port or polish it. It absolutely is not something that should be done by anyone that isn't very good at these kinds of things. You will not gain any horsepower and more than likely will cause new problems.

VERY GOOD ADVICE...NO BENEFIT UNLESS EXTENSIVE MODIFICATIONS ARE DONE FROM TOP TO BOTTOM...I ONLY SEE ALOT OF POTENTIAL DOWNSIDE TO MESSING WITH THE STOCK THROTTLE BODY.
