I'm going to be put a whole list of parts on my car soon and the only thing I don't know where to get is a good turbo. I want to go with some thing that will bolt on the stinger header and work with his fmic. don't think all be going over 25lbs of boost. Also stinger if you read this I will be going with turbo_dad's ms2 kit. Thanks for all the help guys

Are you looking for an upgrade from the stock turbo or a turbo to begin with?
The stock Garrett-T3 on all turbo 2.3's, excluding the 87-88 TC (which uses a smaller IHI turbo) has been said to be efficient up to 23 psi, with supporting mods. It will bolt up to the stinger header, you will just need to clock the turbo so the compressor outlet is facing where you want it for your FMIC piping.
An upgrade from the T3 or IHI, for high horsepower application is generally the Holset series of turbo. Can be found on several different vehicles. One being 01-02 Dodge 2500 or 3500 diesel. They are a larger turbo so they require a significant amout of supporting mods to raise the operating range of your engine. I believe they don't even begin to build boost below 3000 rpm's.

I'm going to be looking for around 400whp. I want some thing that will spool as fast as it can. What about a ball bearing turbo do these help alot. I'm looking to spend less then $1000 on the turbo but I don't know much about turbos and all the different ones. Thanks for any help

Have you read the turbo sizing section of our FAQ? If not, start there, then come back here with a few ideas you like and I'll throw my opinion in from there.

There are literally hundreds of different "t3/t4 hybrids" that support anywhere between 325 and 600+hp. There are also a number of different HY35 variants (HE351, HE341, etc.) but thier differences vary to a lesser degree compared to the hybrids. This makes the variants less important for our needs because they all work relatively well.
Since I'm still not sure if you've looked at the faq page section that covers this, I'll copy it below...
From the FAQ page:
What turbo should I get for "X" hp?
-Stock (87-88 Turbo Coupe) Ishi-Warner IHI: Less than 250rwhp, super quick spooling (full boost at 1800-2000 rpm with a few airflow mods) but runs out of steam at higher engine speeds. Great for heavy cars or daily drivers. Good to 18psi or so.
-Stock (83-86 Mustang/Turbo Coupe, 84-89 Merkur) Garrett/AiResearch T3: Up to about 300rwhp. Full boost at 2500 rpm or so with a few airflow mods, pulls pretty well up top. Has a very hard "kick" when boost kicks in. Great for a daily driver/street terror with minor mods. Good to 23psi or so.
-T3/T4 Hybrid T04E 46 trim compressor/Stage III exhaust side with .48 a/r for street cars, .63 a/r for street/strip. Great for engines in the 250-350rwhp range. Full boost at 3100rpm or so with a header and supporting mods. Nice linear power throughout rpm range. Great for street/strip cars in the 12-13 second 1/4 mile range. Good to 25psi or so.
-T3/T4 Hybrid T04E 50 trim compressor/Stage III exhaust side with .48 a/r for street cars, .63 a/r for street/strip: Great for engines in the 300-430rwhp range. Full boost at 3300rpm or so with a header and supporting mods. Nice linear power throughout rpm range. Great for street/strip cars in the 11-12 second 1/4 mile range. Good to 35psi or so.
-Holset HY35: Great for engines in the 300-480+rwhp range. Full boost at 3600rpm or so with a header and supporting mods. Pulls like a freight train in the higher rpm range. Great for street/strip cars in the 10-12 second 1/4 mile range. Loves 30+psi of boost.
-Holset HE351: Slightly upgraded version of HY35. Great for engines in the 300-480+rwhp range. Full boost at 3600rpm or so with a header and supporting mods. Pulls like a freight train in the higher rpm range. Great for street/strip cars in the 10-12 second 1/4 mile range. Loves 30+psi of boost.
-Holset HX35: Great for engines in the 380-500rwhp range. Full boost at 3800rpm or so with a header and supporting mods. Pulls like a freight train in the higher rpm range. Great for street/strip cars in the 10-11 second 1/4 mile range. Loves 30+psi of boost. Split scroll exhaust housing causes boost control problems unless an external wastegate is used or the divider is cut out.
-T61: Great for engines in the 400-600rwhp range. Full boost at 4000rpm or so with a header and supporting mods. Great for serious street cars or drag cars in the 9-10 second 1/4 mile range. Can handle upwards of 40psi.
-There are also many new GT series turbos that will work on 2.3T applications. I did not include them because they are a much more expensive turbo and since they have many more options available, they should be spec'd out specifically for your setup.
I separated out the section that would apply to your hp desires. Ball bearing turbos do spool a bit quicker but they are also more expensive and MUCH more expensive to fix if they fail.
When aiming for 400hp you need to realize that your rpm operating range will shift up quite a bit. This means the desire to have full boost near 3000rpm isn't quite as important as it may seem with a system with a stock cam that dies after 5 grand. Stock cams make power between 3k and 5k, 400hp setups typically make power between 3.5 or 4k and 7 or 7.5k. You'll see you are working with a 2k rpm range in the first instance and a 3-4k rpm range in the second setup, though the turbo spools up later to allow it to support the power in the upper rpm ranges.
Lots of boost at low RPM's also puts more stress on the rods than it does at higher rpms...something to consider if you are running stock rods.
Want boost quick: Get a 50 trim hybrid with a stg 3 .63 exhaust side. This will cost you 650+ if it is a quality turbo, not a POS chinese version off of ebay.
Want a cheap option that will spool a bit slower but support more power overall? Get an HY35 or HX35 (or a variant).

Thanks for the help stinger. I was not thinking about the rpm range moving up. Which turbo would you pick. I want the turbo that you think will make my car go down the track the fastest it can. Thanks for the help

if you want to get a turbo built for you, you can try Charlie at Evergreen turbo. real nice guy and knows his stuff. he also has an svo and has tried a few different setups i think.
last, i think that he said the holset where a bit too much for him.
his cumming turbo diesel is beefed up a bit in his truck.

Unfortunately Charlie uses clipped turbine wheels and TO4B compressor wheels which are both antiquated technology that doesn't perform nearly as well as the newer stuff...and you can find the newer stuff cheaper.

stinger you say that the hy/hx like 30psi or better but will the stock studs and gasket hold up at that level.?

You certainly don't have to run that much boost but typically it's more about how good the tune is rather than how much boost you are running. Even a basically stock 2.3T engine at 30+psi with a Holset (and proper sized injectors, good exhaust, and large intercooler) will make nearly 400hp which is getting to the point of needing upgraded fasteners.
