Turbo Upgrade (do I need it)?
#1

Hi everybody!

So I'm in the midst of flattening the head as part of my servicing that I'm doing for my head gasket and I see that there's a T3 Garett turbocharger being sold here for 120USD. Is this worth it and also, is this a true Garrett T3?

He claimed that it came out of a scrap thunderbird 87 turbo coupe.

What would happen if I put it on? Do I need a pair for both of them 2 work well?

If I had a Garett and an IHI would that be ok? 

How do I know if I have IHIs in my bird?

Do I have a manual boost controller in my car?????

Feel free to let me know.

P.S. The fourth image is the one im tempted to buy, the 1,2, 3 are from my car

The turbo in pics 1, 2 & 3 is an IHI, which was the OEM factory-installed turbo on '87-'88 TurboCoupes. The turbo in pic 4 was (obviously) made by AiResearch and is PROBABLY a T3. BUT......due to the inlet configuration, it appears to be one that originally came on a '79-'82 carbed (draw-thru) Mustang and will not fit on your car (at least not w/o extensive mods & fabrication, since the exhaust housing is also drastically different).

What is your performance goal? If you just want a nice street/daily-driver "hot rod" that'll squirt from signal-to-signal, I suggest keeping the IHI that's presently installed. It has slightly-less flow potential than a T3, but spools quicker and gives a better seat-of-the-pants "feel"......especially with a 3-inch exhaust, less-restrictive air inlet and a slight increase in boost (which might require an octane booster, depending on gas quality in your area).  <shrug>

Agreed, that's a carb turbo and will not work on your engine. 3rd pic appears to show a home made boost controller.

I can't seem to figure out what you're asking by these 3 questions:

"Do I need a pair for both of them 2 work well? If I had a Garett and an IHI would that be ok? How do I know if I have IHIs in my bird?"

They all seem to insinuate you either want to run twin turbos, or are under the assumption that you have twin turbos?

My question is, if I had installed 1 garett turbo, and then 1 IHI turbo, would that be ok.

TurboRay My only goal is to break to 200 Horsepower. Just being in the 200s is nice, idk! I'm not here to race, just something with a tiny bit of more speed without buying excessively priced parts.

I find it weird as the seller talked about how he ripped the turbo directly from an 87 ford thunderbird twin turbo. Is there any way to inspect turbos specifically?

A seperate question. Where is the second turbo in the turbo coupe? I spotted one in my pictures, but where's the second one usually?

The seller is an idiot (or at minimum severely misinformed). There is no twin turbo 2.3L in the Turbo Coupes or anything else. Furthermore, it didn't even come from a Turbo Coupe, it came from a carb turbo Mustang from 79-82 (before Turbo Coupes existed). So ignore every single thing the seller has said as he doesn't have a clue what he's talking about.

The stock IHI turbo you have can support more than 200hp (stock is 200hp in 87-88 Turbo Coupes). You just need some mods to add power (3" exhaust, front mount intercooler, boost controller, and cone filter mainly). Those items will allow you to add 50hp or so. We have all of those items on our site.

The first thing you'll want to do is a good tune up. Replace your fuel filter cap rotor plugs (standard plugs never platnum) and wires if you don't know how old they are. Then make sure you only ever run premium fuel. Now the fun starts. The first and cheapest mod is to find factory boost solenoid on the passenger side inner fender. It will have two vacuum lines running to it from different places on the turbo. All you need to do is run a new vacuum line that connects the two places on the turbo the lines run to and from completely bypassing the valve on the inner fender. This will give you a solid 17 psi boost at all rpm which will give you a very noticeable power increase over the factory 10 psi until 4500 rpm and 15 psi after that. You can leave the fuel switch on premium which will give you more power but it won't run on regular fuel anymore no matter the position of the fuel switch. Next up is a free flowing intake and exhaust system like Stinger said. Both make a really nice gain in horsepower. With a free flowing exhaust, a good tune up and good 92 octane fuel you should be able to bump the base timing up to 12 degrees instead of the factory setting of 10 degrees. Again depending on local fuel and outside temprature. The final step is disconnecting the factory knock sensor which can save your engine but is also known for pulling a bunch of timing because it picks up false knock not caused by detonation. If you don't know what detonation sounds like don't do this. Thses mods should get you to 240-250 hp at the crank and a huge bump in torque.

No, it's not a Garrett T3. '87-88 Thunderbirds only came with IHIs.

The car only came with one... Huh

It says "IHI" on the compressor housing and looks like your pictures #1-3.

Only if you or someone else installed one.
