Save your $ on the TB if you have a stock engine. The cost is not worth the little to no results. Plus, your intake has a 83 mm opening so adding a 87 or 90 mm TB to it is basically defeating the purpose.

Now if you do some engine upgrades like cam, heads, headers, supercharger, etc., then a larger TB would be more beneful as long as you open up the intake opening.

I have a few mods, Leg Maker True CAI, RESO delete and Super 44's. I did some research and found that a larger throttle body would give a quicker throttle response.

I bought a TB from Fastmann Throttle bodies, and I was an instant differance. My car pulled a lot harder than with the stock TB. You feel it all the way through your shifts.

Here is some info from his W Site.

-Front Side Taper Boring: The opening of the 801 and 805 TB is Radiused and Taper Bored to almost 85mm leading back to the stock bore.
The 847 has had recent changes. It has the same radius and opening but now leads back to a bigger 81mm bore.
-Half Shaft: Modified Factory Shaft. The top of the shaft is removed providing extremely smooth airflow across the top of the blade and an additional +3.50mm more airflow at wide open throttle.
-(Optional) Backside Bore: I can also offer an optional Backside Taper Bore. The back side is taper bored to match the manifold opening very closely.
