    throttle body issues/concerns

    ive been reading what you've guys have posted over time on here about throttle bodies and spacers on our boxes and im still not quite sure if i can increase my own throttle body's diameter to just 63mm by boring it out or if i can just buy a mustang 65 or 70mm throttle body and just rearrange the assembly on da bottom so i can flip it over to fit our crown vics? most of you guys have the H.O. and well i guess u can just add any mustang throttle body and spacer. so wat do you guys recommend for my stock 5.0?

    Stock mustang 60mm throttle body and bored out vic EGR


    No reason for anything larger than a 60 on a stock lopo. And if you are not swapping the upper intake to an HO upper, the HO TB swap isn't worth it either.

      some of you guys do have the throttle body and spacer etc, what kind of differences will i notice? ive been told that gettin a bigger throttle body is a minor adjustment to add to my cv. mrltd, why only 60mm? will 65 or even 70mm not make a difference? and if i get the stock mustang 60mm, what modifications will i have to do to it in order to fit?

        There is no need to upgrade to a 65 or 70 on a stock motor. It's just too big.

        My 16.03 second lopo (which is a record around here and CVN) was running a 60mm. The only mod is the linkage on the TB. It's a little grinding and welding or drilling and tapping. But, as I said, it's worthless on the lopo upper intake. The inlet on the lopo upper is so small. Also, you'll need to bore the EGR out to match the TB...

          And if you are running stock exhaust....get rid of it. That's the biggest restriction in the whole car. Need dual 2.25 at least. Exhaust first, then everything else.

            i already have exhaust, installing bbk's and probably straight 2.5 to my already installed 2.5 pipes and dual flowmasters. no cats of course. da mod on the TB would be rearranging the assembly underneath it or the lil brass pipe dat sends air over to the oil covers which i would have to turn around and make sure its sealed shut right?

              You need tyo swap the linkage from the stokc lopo TB to the HO. It's easy. The tube just swivels around, No need to put any sealer or anything on it. As long as it's still snug in there you're fine.

                Even a 65 on a stock HO with stock Panther exhaust doesn't work well. I ran that on my car for a while, and it was poo. I stuck the 60 back on, and it was better. Gonna put the 65 back on one of these days now that I have decent exhaust to see what it does. The other concern with a bigass throttle body is the intake quite simply won't flow enough to take atvantage of it. If you look inside a stock HO upper, its not the best looking thing in there, and really a 160 hp motor doesn't need a huge throttle body.

                  check this pic out, pretty cheap on ebay and wanna add it as my spacer on my ride but wheres the other pipet or spout? on our vics, if stock, the spacer has 2 spouts, right where the white arrow is pointing at. so this wont do huh? theres some other spacers like this one but with another pipet/spout right where the blue/green arrow is pointing. or should i just keep my stock spacer and bore it out to 65mm?

                    The throttle cable bracket won't bolt up to that. You're looking at one for a Mustang or Mark VII. The EGR cooler hoses aren't real important, its the throttle cable thats hard. And yes, the other pipe should be behind the stud where the arrow is.
