I know there are a few threads on here about the whole turbo vs supercharger thing, but none that answer my question directly for a 1994-1995 GT (or 1987-1993 Foxbody because it's almost the same exact engine.)

I have a 1994 Mustang GT and I think once I get it running and insured I want to add a supercharger or a turbocharger (adding after because my insurance rates will already be high because I am 16, that kind of HP adder won't help with said rates).

It seems that superchargers are around $900 less on average (from what I've seen) but Turbos give you more adjustability and more potential horsepower.

I am also debating the intercooler, makes sense to get to keep temps cool and horsepower output high, but is it worth it? and if so which kind does one get?
A small one like this http://www.americanmuscle.com/mishimoto-intercooler-zb.html
Or a bigger one like this http://www.americanmuscle.com/mishimoto-intercooler-mb.html

I also am curious to see if anyone here has installed one of them on a 94-95, and if so what else did you have to change? What has to be changed for fuel delivery and so on?

My current setup is as follows (some parts I just ordered a few minutes ago)
1994 Mustang GT
5-speed manual
Generic CAI from AM 5.0 Mustang Cold Air Intake Kit (94-95 GT) at AmericanMuscle - Free Shipping!
Flowmaster header to tip Exhaust
3.73 gears
BBK 190LPH Performance fuel pump
MSD cap & rotor
Ford Racing high performance 9mm spark plug wires
MSD TFI performance coil
Might be forgetting something
Motor rebuilt 20,000 miles ago, 138,000 original

So can anyone recommend a brand for either a turbo or supercharger?
Anything else I need to upgrade?

Added a poll just to see who prefers what.

honestly you have to add about another $5000+ to your "wish list", first of all a small block does not have the flow needed to support a blower or turbo in stock form, so first build the daylights out of the motor with Trick Flow heads, intake, cam...then you need a stout fuel system, then you need custom tuning install of the parts etc, of which the 94 is not suited for very well since the electronics are primitive
If I was you I'd skip boost and build a great 347 stroker, off the shelf parts can easily put it in the 400-500hp range...or do what I did and build the 351w stroker, 427, 600hp NA
But don't get me wrong, supporting mods are very expensive and the list of the needed parts never ends with big hp cars, this is what very few realize until their wallet is smarting from the cash your tuner will demand for all the "oh by the way" items
Custom headers alone for my build were $2000, custom electronics were another $2000...can you feel me?

With either a turbo or sc will be enough to split the stock block.

This subject will require plenty of reading and will be kinda tough to elaborate enough on a simple thread.

I think roots blowers have their place, but as far as centrifugal superchargers I think they're a turbo missing the turbine. A centrifugal supercharger is a belt-driven compressor. A turbo is a compressor too, but instead uses a turbine to drive it instead of using engine power.

But, those are just my musings. I think superchargers and simpler to install, but I feel a turbo is the much more sensible way to go. I haven't owned anything with forced induction to date, but I started the planning for a turbo project. Not a Mustang, btw. :smoke:

Imho, I think better pole choices would have been:

• Centrifugal supercharger
• Roots-type supercharger
• Intercooled turbocharger

Disagree - you can get huge gains adding by adding boost to stock heads. Something like an 0n3 turbo plus fuel upgrades can give an all stock 302 more HP then it can hold. I dynod 397 on a mustang dyno with gt40 heads and 11 pounds boost. I could easily add more boost but I'm not certain the block will hold it. The turbo is capable of more boost to get stock heads to the same level.

 

[Khralen]

From my understanding you can pretty much bolt up a turbo or supercharger to a engine with the only needed modifications being fuel delivery, granted you don't plan on going over 10 lbs boost the stock engine should be able to handle that.

Just grabbed these 2 for reference.
This super charger is supposed to top the engine out at 319 HP w/ 370 torque
Mustang Vortech Supercharger System - Satin (94-95 GT/Cobra) 4FG218-020L - Free Shipping!
This turbo should top my engine at 397 HP w/ 490 torque
(second from top on this page) Turbo-Kits.com - 87-93, 94-95 & 2005+ Ford Mustang Turbo & Twin Turbo Kits

Now I would imagine putting out upwards of 400 HP would ruin the block as the stock 94 GT came with like 220 HP or something? So that's doubling what it originally had.

MY 85 GT and and I have chatted about this on another thread. I'm easily about $3500 into my KB supercharger. That's for the S/C and several different pulleys. On top of that, I have the aluminum heads, upgraded injectors, TB, intake, MAF, fuel pump, cam, and some ARP hardware inside the motor. Add also the custom tune and chip...

Compare that with what he spent on his On3 turbo kit...$2100 which included many of those upgrades I already had.

With his set up, he's breaking traction at 50mph..I can't do that. Granted I have a touch less boost and different rear end gear, but still.

It appears to me, at least between me and him, his dollars and cents netted a way better return with his turbo versus my supercharger.

That's why I started this thread, I am trying to figure out what I am going to be spending on stuff other than the turbo or supercharger (tunes, fuel delivery, anything else that is needed). Because I don't want to pic the supercharger because it's cheaper and than have to go back out and pick up stuff that came with the turbo or stuff you don't need if you have a turbo.

What you just said makes me want to go with a turbo for cost reasons, and it seems he's pulling more hp than you are at about 1,000 less. I can live without the infamous supercharger whine if I am getting way more bang for way less buck :bigthumbsup

I'm sure Gerard will chime in when he sees this thread. He's run both superchargers and turbos, so he's been on both sides of the fence.

 

[fast9050]

I don't know if you subscribe to any of the Mustang publications, but almost all of the super high horsepower motors are running turbos, comparatively speaking. At least that's what I've gleaned from reading those stories.

Yea my friend has a ****** old 4 banger Honda civic and he was never even close to as fast as me, but her threw a cheap turbo on and set it to 10 psi and he now can beat me in power, that's kind of embarrassing at school when I'm the kid always bragging that my car is so much more powerful than all of their ricers, and I'm also the only one (student and school staff) that has a American muscle car, their all imports and crap. So I am trying to keep up with them but I simply want the best bang for my buck without spending insane amounts of money.

There's nothing wrong with a lesson in humility either. Don't brag..just beat 'em.

My bad shouldn't of said brag. Its more like this:
THEY brag about there new car
I trash talk there import
I show them my car
They piss themselves after seeing the American made V8. LOL
But now that my best friend is faster than me on half the cylinders? I can't let that happen! lol

I understand man. It's a tall order, I know it...

Have you ever read the kids book "If you give a mouse a cookie"?

Adding a turbo is alot like that. The list of things you'll need after the turbo goes on is endless. If your looking for the cheapest option then keep it stok. Put on the Tubo if if want to have some fun......

Where's DFW metro, TexasMustang?. I lived in Farmer's Branch for a while, back in the late '80's. I got my remaned 306 from AER Manufacturing in Carrollton.

Ok Ist off I have run ever power adder from a roots to a centrigual,to nitrous...to turbo...If you want around 350-400 rwhp then i would go with your stock long block...70mm TB,340 lph fuel pump,42lb injectors,The On3 turbo no more the 10psi..you should make decent power have a fast street car..OR you can do say a trick flow top end kit and then bolt on the on3 kit NOW your talking..lol...But rhis isnt cheap...dont aks what im into mine for...But the car is fast makes awesome power!!! and is Really fun to drive...:bigthumbsup

So your saying if I get a 70mm Throttle body, a 340lph fuel pump, 42lb injectors, and a turbo set to 10psi I'll be pushing out around 375 RWHP without worrying about my block? I am also thinking of taking an Explorer upper intake out of the local junk yard and throwing it in, how much would that help?

How much HP can you put out without upgrading internals anyways?

Dang, not familiar with that.
