I did it. Swapping them out wouldn't have taken long at all had I not broke my dipstick handle off. Lesson: Remove oil dipstick when installing throttle body.

It isn't difficult. Just a handful of bolts, really.

This.

Also, it made a significant difference in throttle response and probably a few hp. I painfully remember the throttle lag the car used to have, that was completely eliminated with the new throttle body.

One thing to remember is that you need a Mustang TPS...the Focus sensor rotates the opposite direction.

focus rotates in opposite direction does that mean you have to rewire it?

No...it just means that you need the Mustang TPS.

Most of the time the better_feel_in_response is beacuse with the larger TB your flowing 100% of the air it can use with only 75% throttle. That does'nt really mean 25% more flow, just mean's that last 25% of throttle does'nt do any thing. So pushing the pedal down 3/4 is really full throttle.

I thought we were talking about adding a Mustang Throttle Body to a RC NItro Car.

I think its a Mustang TB from years 95-99? I could be wrong though.

Hi there. Totally new to site and am stoked to see people still working on the Mustang tb for the spi.
This is the question that is killing me: Where does one find this mysterious adapter for this swap?
Any info greatly appreciated.
Doug

No. He means the plate(s) the is the intermediary for the throttle body to bolt to which, in turn, bolts to our manifold. The bolt patterns are not the same, so 2 plates need to be machined for this to work. One plate that would be bolted to the manifold. The second plate is then bolted onto the first plate. Finally, throttle body bolted on to the 2 plate.

Breakdown post intake removal:

Unplug TPS.
Remove throttle-cable plate.
Remove 4 bolts holding OE throttle body in place.
Remove old gasket.
Add new gasket.
Install 4 bolts for adapter plate 1.
Install 4 bolts for adapter plate 2 (shared bolts that hold throttle body, iirc).
Elongate TPS wires if necessary (I had to, others didn't--straightforward either way).
Flatten throttle-cable plate.
Bolt throttle-cable plate on other side of throttle body.
Plug in TPS.
Drive.

BEWARE! If you intend on doing this modification, DO NOT LOOK AT THE "AFTERMARKET PARTS AND MODS LIST" ON THIS PAGE! This link tells you everything that needs to be done; from years/parts/donor vehicles, to required machining, to step-by-step installation procedures WITH pictures! STAY AWAY FROM THIS LINK!
