not really. the steps and things you have to rework (EGR, IAC, intake) are well documented and considering you'll save about $600 (assuming $700 for an SVT and $100 for a 3.0L UIM) then it doesn't seem like that big a deal

You wont need a chip for the 3.0L TB/UIM. The reason its alot cheaper is because there is a large supply of these and not a huge demand in the aftermarket. However, the 2.5L SVT UIM/TB are scarce and there is a large demand since they are SVT.

because every 3.0L duratec taurus on the road has one

there are more taurus's put on the road every year thatn probably all of the SVT's Contours combined

and your chip will work, but optimally it needs to be dynoed, tuned and reflashed everytime you change something on your engine

I have one from a 96 Taurus that's going on my car as soon as I get a throttle cable and another EGR valve to cut up. You want the aluminum one, not the plastic one.

are there any issues w/ the 3.0 throttle body and the AEM intake? what is the size of the 3L TB? 60mm ?

also, will a 3L LIM fit?

I don't know the exact dimensions, but you can put the ENTIRE END of the 2.5 TB Iinside the mouth of the 3.0 one.

I strongly disagree.

The 2 UIM's are not remotely the same in design and therefore will not generate the same power increases or power curves.
On top of that the 2.5L cams and programming are setup to run individual long & short runner style manifolds.


The design of the 3L manifold "should" help the mid range while the 2.5L "Will" help the entire powerband.


Also have we ever seen a back to back between a DH 2.5L UIM vs a 3L UIM. Exactly my point. Speculation is not what I would call "Hard Data"
