v-8 70mm Throttle body Install-working out the bugs

RubySlow · August 26, 2007

Okay so I purchased a 70mm T-Body From Dynamic racing. It looks fine and all... its for a 1987-93 Im thinking this is the problem?
Well I took the old one off and then compared the 2 and everything is different. The TPS Bolts, the throttle hookup, the IAC so What should I do?
It would be alot of modd.. just to get it to work.
Or Do I need another type of throttle body?

I think you might need one for 94-95 or one fore a gt40 upper. I am curious also.

This is the only bolt-on I am missing.

Turdle · August 26, 2007

there are 2 bolt patterns-94-95 mustang is a rectangular shape pattern-explorer and 89-93 mustang is square.
Which do you have?

RubySlow · August 26, 2007

Well the t-body is square and the gaskets that came on the kit fit perfectly with the original t-body, I did bolt it up and eveything lines up fine except everything I stated in the first post.

Jon I thought you said none of the mustang throttle bodies would work with out extensive modification, like what you did to yours?

Turdle · August 26, 2007

To be honest-I encountered the same issues-plus some as I even changed the egr elbow on mine--
I used the proper TPS and wired the proper connector to my harness--the IAC will mount although it looks backwards and a bit tight-I used a ball adapter to the linkage and the throttle cable clipped right on it-
Now, to be honest I still have throttle bracket issues-but you shouldn't encounter this using the stock elbow.Hopefully my issues are soon to be sorted.

You might post up some pictures of your problem areas-

Ok I was thinking the same thing with the tps maybe one off a mustang? and the IAC. But like you said.. the Ball adapter Is at the top of the new tbody and On the Original its at the bottom SO I just have to figure out how to adapt the throttle hookup. because when I went to connect the cables the throttle is pulling in the opposite direction. WHen you hit the gas it want to close the Tbody

Yeah--
I was able to find a threded post with the ball on the end-Maybe you could drill a new hole for it on the opposite side?

I am thinking for mine-(just for ideas for you) I am going to cut the lever off, and weld it on into a slightly different angle-mine won't pull all the way open-

I had to convert to front pull because of this-but to be honest I need a picture of yours to refresh my memory--lol

I used a 95 mustang cobra TPS--it is a bit higher$$ but the 95 mustang TPS goes to 4.2v. cobra goes to 4.9v Believe it or not.

if you guys could post pics on how to convert this thing i'll probaily be doing it, a bigger throttlebody is a really great mod to boost up throttle response.

RubySlow · August 26, 2007

ok Pics!

Here I just took a few to give you an idea...

Here is the aftermarket ones first

then the Orig...

Oh John I just bought this....

its for a 1995 cobra Its made by wells

Xan · August 27, 2007

ok so couldn't you just hook it up to that ball then you may have to bend or move your throttle bracket back a bit so i opens all the way?

No I thought about that, And the bracket is pretty ridgid its made not to flex a whole lot...
And the original bends like

And the New one Bends like

you would need to adjust the cables and then re locate the bracket..
It would seem easier to re-locate the ball to the the location It is on the Original T-Body to the new T-body

You know what this reminds me of the shift lever In a AOD or any other trans, A floor shifter has a down position?,
and a column Shifter has a up position shift lever?....

Xan · August 27, 2007

i wanna see how the mustang set up looks like...
hmm you think you could get a junkyard mustang bracket and cable and bolt it on?

chriswells78 · August 27, 2007

I'm gonna be getting my head arount this soon too. I just bought a 75mm Edelbrock from Ebay and I'm gonna have to jerry-rig it to work right too. I may just fabricate my own arm and screw it to the existing arm, then cut off any excess arm parts sticking out where I don't want them.

I have those-on the shelf if that gives an idea how well I think it will work--

I'll dig it out and get pictures---remind me if I don't do this by this evening--

Xan · August 27, 2007

right right, theres a nut holding the arm on. Hmm you think if you took off the arm and fliped it and put it on backwards, then switched the side where the ball is (probaily saw off the other side of the arm) it would work?
Either that or make a new arm or rip the old one off the stocker.?

RubySlow · August 27, 2007

Ok So i had the guy at the exhaust shop cut off the ball and reposition it to the proper location. Im going over to get it right now... I will have pics and hopefully it will be with the new T-body on

RubySlow · August 27, 2007

Ok so I got it on and It works......

So I had that ball cut and re welded in a new position...

And here what it looks like once I first get it on..

Now the tps sensor on.. Had a mustang one lying around...

Now the Throttle bracket and cables hooked up..

Put the Old intake tube on

I need to fine tune it still having a minor issue with the kickdowncable but it works. Nothing is ever just "Bolt-on"

I hope that I can do something with a Mustang TB when I get to doing mine. I'm glad to see that you worked it out.
I swapped an 88 GT engine into an 86 Crown Vic in 1993. I used an 86-93 Mustang TB and fabricated longer throttle cables to work on the "reversed intake". I've had top play with that stuff also, using a common part like the Mustang TB is usually best, because future changes are then very easy. Regards,
