Does anyone make a bigger throttle body?

The stock throttle body is 50MM. BBK makes a 56MM one that works, but requires you to reuse your current throttle shaft. a 60MM unit off a 3.0 Duratec Ford Escape works but requires filler to make it seal.
With the stock throttle body being so small and the 3.0 being such a revver, going to a larger throttle body should show some improvements. You probably shouldn't go any larger than 60MM though...unless your making over 250HP.

Recent thread over on ---. This guy used a Sable/Taurus Duratec TB. The difference between the Sable/Taurus one and the Escape/Tribute is the throttle linkage is on the opposite side for the Sable/Taurus. More work is involved.
**it doesn't like the link for some reason. It is in the 3.0 section over there**
As for the Escape one

I expect gains would be minimal, except for better throttle response in the low end.

The escape one is the one to go with. The taurus has the linkage on the wrong side. It can be done but more work is involved. That cardomain link seems pretty straight forward and pretty much sums it up. It was the most information I could find.
I need to get motivated and do this myself. I have had the throttle body laying around for months now.

Horsepower gain from putting a larger TB on a stock engine = ZERO.
That's the reality.
Any perceived increase in throttle response is false. It is simply because a bigger TB will flow more at any percent throttle opening. So it's the same as just putting the gas down a bit further with the stock TB. But at WOT the flow will be the same, because the stock engine will not out flow the stock TB. The stock TB is small because the engine doesn't pull much air.
