I'm looking at either the Edelbrock, or Ford Racing 65mm TB. Are there any other parts I need to make the swap besides a 67mm EGR spacer? Thanks!
Same question,whats a TPS,and how do you adjust it?colemanitis said:From what I've read, a mildly modified stang doesn't need anything larger than a 65mm TB - is this not correct? Also, what's a TPS and how do you adjust it?
Is that absolutly nessasery when getting a new tb?Fox Saleen 163 said:TPS (Throttle Position Sensor) It's the electronic device on top of the throttle body. It's black, has two screws holding it down and has 3 wires coming off from it.
You adjust it but doing the following:
1-Turn key in ON position, but engine off.
2-Place POS Multimeter lead on Green, NEG lead on black. (you will have to go through the insulation obviously)
3-Loosen screws and rotate TPS sensor in order to get as close to .99 as possible without going over. .95 is fine.
4-Tighten screws back down.
To get a high reading, close to .99 you might have to elongate the holes in the TPS sensor using a file or small drill bit. It's plastic so be gentle.
You see,it pays to ask questions!I asked a half dozen people if it is just a bolt on,without having to do anything else,they all said yup,just take the old one off and put the new one on!HAA5.0GT said:willys, yes it is necessary, since you have to swap over the tps to the new throttle body. If it is not set correctly, you could be losing a good amount of power. FoxSaleen is right on about how to adjust it. Mine is somewhere around .97, which I set when I put in my 65mm tb. Also, I would stay with a 65mm for your mild combo colemanitis.

Is there a need for the spacer?1Stang2Go said:You'll need a regular voltmeter to adjust it. Sometimes you may need to open up the two holes in the TPS to get the right reading.
I ran a 70mm Accufab on a near stock (gt-40, 76mm C&L, 24's, 1.7RR, headers) with no problems. I swapped it out for a 65mm and noticed no significant changes.
Accufab makes the Best quality, best performing, and best looking TBs and spacers out there.
ACCUFAB gets my vote...
