Is there any other TB we can make work besides the mustang? Surely there's some Chrysler vehicle with a 55 or 60 mm that would be just as easy to fab as the mustang. Any ideas?

The thing with the mustang TB is the ('01-up) IAC valve is practically a bolt on. I used some JB weld as filler in the IAC opening, but IDK if it was really necessary.
Of course any TB will work, just do a remote mount for the IAC valve.

There are some nice TB options on ebay....

i found a 01 mustang gt throttle body will that work what do i need with it to make it fit?

Yeah I've looked over all BRR's threads and HT on the mustang TB, and some of yours too. I could do that, but I feel like 65 mm would be plenty big, and I'd do just as good with a 55 or 60. I could be wrong. Plus it also seems to me that there should be a Chrysler TB that would be fairly compatible with our sensors, both being Chrysler products. Do you think it would be possible to run a different IAC motor, like you can run the ford TPS?

i hear a jeep 55mm would work good

Any certain years or engines?

cant remember but i thought it was like early 2000 cherokee but im not sure

The jeep throttle body is what the avenger and eclipse guys have been doing for a while, but we would need a similar adapter like the one for the mustang TB.

These are the only real threads I could find on short notice.

Those aren't for the 2g neon but there are pretty informative.

Most Mustang TB's are 60mm. The one in my 1st post is a 60mm. I ditched the 65. (Since BRR is currently selling his, I'm not putting it up for sale. I may adapt it onto my XJ)
There isn't much info floating around on TB sizes. If someone has a chart that would be awesome.
Chyrsler TB's don't lend themselves to easy adapting due to the fucked up shape of them, and try finding one on ebay as cheaply as a mustang TB. The one pictured above was a $12 purchase. JY may be another matter.

I respect you desire to stay MoPure, but you are truely limiting your options.


BBK does offer a 56mm bored out version of the 49mm V6 mustang TB, for about the same $ as the Modern 60mm and the TPS is a direct bolt on, as the mounting screw location is the same as the neon TB. So that is even easier than the 60mm. All that is needed is the cable pulley. This may be a nice option for NGC ppl.

god damn, 90mm. That could suck up small children and puppies.

Not toraise up a dead thread but u have my wheels turnig on your last statement. Is this true?? 56mm TB!!!!

Is this true??

Very

If only it had an extra bracket for CC....

+1
plus for 250 ill take my shot w/ the modern one.

That 90mm is actually a really nice piece. Hmm, Grrtrude may like one of those.

I doubt the pulley would be correct for our application.

You would still need to source the cable pulley from a spare TB.
This way the CC still works. (It does on mine) It takes some getting used to tho. The CC is very responsive.

Yes for the price, the MPX, or Lorenzo is a no brainer.
But if you don't want to risk a CEL (Maybe) or are uber anal about the CFM requirement for the engine....

Also like I said before, the neon TPS is a direct bolt on with the V6 TB vs the V8, which is rotated 90º.

Which reminds me...

How do you get the throttle cams off the neon and mustang tb's???

The neon one is a PITA. I drilled the end where the shaft is molded into the plastic. Then used a long punch, and an arbor press to push the throttle shaft out. Or you could just cut the shaft off flush. I then just drilled some holes, and bolted it to the Mustang TB's set up.

looks like fun...

It also looks like I am going to have to drill the mustang throttle cam out also.

With the Iac sensor...

Couldn't I just use a newer style instead of the 00?

I have never seen both of them side by side, But I'm assuming they have the same wiring and plumbing just with slightly different designs.

You will need the IAC adapter that MPX sells, if they sell it separately from the TB.

The '00 has 4 wires, and the '01 up has two wires.

Did you plan on using the V6, or the V8 Ford TB?

The 60/65mm just bolt the cam to it like shown(V8 ). But the ford TPS needs to be used, or an adapter like in my how-to.

The 56mm might take some more thinking. But no TPS adapter needed. Pros, and Cons...

I'll see you on the 90MM LS1 TB, and raise you a 105MM Fox-Body Mustang TB. It flows 1,504CFM. Should be plenty for a Neon.

As I know any TB bigger than 55mm actually hurts the performance. correct me if wrong. MPx 60mm is still a little bit big.

At 8200 RPM a 122 cubic inch engine will need 290 cfm at 100% volumetric effiency, using the formula ((Max RPM/2)*Displacement)/1728. Rule of thumb is to go 10% over because a naturally aspirated engine can go above 100% volumetric efficiency because of cam overlap, header design, etc. Go above that and you kill low end because of reduced velocity, go below that you starve the engine for air at top end. 110% is volumetric efficiency is 319 cfm."

Based on this, 55 mm does seem to be the option for naturally aspirated (non-turbo) engines.

It only hurts performance, if you go WOT all the time, and can't learn how to use your right foot.
