fox tb conversion ?

[94GTMOOSE]

so i serched a little and couldn't anyone explaining the bedifits and disadvantages of doing the conversion. I recently aquired a gt-40 intake for 250 from my brother. I want to put it on but i have a small budget to work with becasue i am swapping the aode to a t-5 and thats where my money is flowing at the moment. I have a stock tb of of his 90 and it is in perfect shape. i have the bracket too, but not the block off or the cable.

1. Is there really any gain of power and/or toqure?
2. Can i still use my strut tower brace, and if no do any aftermarket braces fit?
3. Will the hood close or do i need to mod that?
4. does anyone make a maf system to go with the conversion?
5. will a stock 90 tb work with the conversion
6. do i need to change any electronics
7. what else do i need to completle project

Sorry if you guys answered these questions already but, i serched and couldn't find exactly what i wanted to know.

1. That's yet to be determined by anyone on here. I know one guy lost .2 in the 1/4 with it, but at least one other person has picked up time in the 1/4.

2. STB might fit with the right air intake setup. Most guys have theirs removed tho.

3. The hood should close just fine as long as you use the fox IAC, which uses the same electronic connection as the SN95.

4. Not that I know of. You might be able to get a fox, or possibly 96-98, CAI to work.

5. Yes, stock tb should work.

6. You will need to use a fox IAC and TPS. The IAC will plug in fine, but you need the connector from a fox to plug in the TPS. Or you could wire it in directly. Look at the 94-95 FAQ for the color codes.

7. Read the FAQ for a list of everything needed for the conversion.

it just sounds like a lot of work to do, for such little pay out. No proof of HP or TQ, just as expensive as doing it the way ford intended. I think i might just order the adapter from Professional Products, and aslo their tb. they are take offs of the edelbrock stuff.

I was in the staging lanes at New England Dragway about a month ago and a guy had a '95 Mustang GT behind my '94. We talked a little bit and he told me to never buy a Professional Products throttle body 'cause his is always sticky.

Why would you need to change your MAF? As long as you can get some form of intake tube to it, you should be all set.

You'll need a new MAF meter. There are a few options here, companies like Granetelli and Pro-M (now massairflowsystems) actually alter electronics in the meter for the type of injectors you are running. C&L uses the stock electronicsand sample tubes of varying sizes for the type of car and injector you are running. The good thing about a C&L is you don't need to spend a lot of money on recalibrating the MAF like a Pro-M or Granetelli, you just buy another $30 sample tube and your'e done. A lot of people don't like C&L because they reuse the stock electronics, but my friends and I have run them for years with no problems.

Again, if he's staying with stock injectors, he shouldn't need a new MAF. If you read up on injectors and MAF sensors at http://fordfuelinjection.com they explain why you should use a stock calibrated MAF (19lb/hr) and go with a computer tune to accomidate larger injectors. You can use an aftermarket MAF, but stick with the 19lb/hr calibrated ones. The computer is expecting the voltage curve from the 19lb/hr MAF. Ford even did this with the '94-'95 Cobra. It has the same MAF as the GT, but the computer is set up for the 24lb/hr injectors that were in the Cobra.

His only concern is the tube that connects the throttle to mass air. I ended up taking a tube off an 89-93 mustang and added a 4 inch to 3 inch reducer from lowes. This allowed me to connect mass air to tube. I cant verify performance gains because I changed a few other things on the car at the same time of swap. I can tell you that it is a heck of a lot cleaner in there and a lot easier to work on the passenger side of engine. I also hooked up cruise.

if not a pro product, then what. I am looking best bang for the buck. should i look for a used ford motorsport 65mm, or should i just pony up the cash and get a acufab. This project might just turn into a whole induction swap, intake mass air meter, tb, MAF. God, it was so much eaiser when i drove the SHO, there wern't very many options.

If your still running the stock heads and cam, there is no reason to spend the money on an MAF or TB. Id just use your brothers that he gave you. Wire it up, and be set. I also, have heard horrible things about Professional Products, and dont plan on buying any of their stuff. Also I remember reading about a guy that did a Fox tb swap and gained ~10 rwhp on a h/c/i car. Which is usally what Fox's dyno above us with the same mods. I've also heard of better throttle response with the swap.

DaveB is pretty much right that the TB and MAF won't do too much for you right now and the stock fox TB is fine for now.

When I started buying parts for my Fox swap (still need a few more parts) I didn't have a fox TB so I figured I would buy one that would support future mods to the motor. I found a good price on Ebay on an Accufab 70mm w/ EGR plate from Mustangwarehouse. It was actually cheaper than an Edelbrock 70mm w/ EGR plate from Summit and had free shipping. Go figure

I wasn't telling him to get another MAF, I was just answering question #4 about MAF. I think the people don't need a new MAF until they need larger injectors., but what exactly do you mean that people can get away with using 19# injectors with a computer tune? I couldn't find the infor on the webpage and it seems that 19# injectos are maxed out quickly espcailly with a custom tune.
