I have always wanted to turbocharge my tc but lacked the money to do so, and just tonight my friend, who owed me for paying off subwoofers n an amp for him a long time ago, has offered me his old universal STS T3 Turbo w/ universal 440cc injectors and boost controller w/ some other parts in exchange for the debt. Obviously, I'm taking this either way as they are worth more than his debt to me, even now. He originally put the turbo on his 4.7L 2001 Dodge Dakota, but the turbo caused him to throw a rod or something, I forget, after about 5000 miles so he had to swap out the engine and left the turbo off after. The injectors haven't been used as, even though universal, he couldn't get them to fit his truck. Apologies for the story, my question is do you think this would be worth it to use (as I would extremely regret causing damage to my car, obviously) or should I sell? I would love to put on my car, but also what would be the best way to do so: I can find the time and borrow a car to have friends help me put it together or how much would professional installation cost, and what would be my best setting for my boost controller to keep wear on my engine at a minimum with still good increases in power?

 

What are the A/R's of the impellar and turbine?

 

Don't know yet, I don't have the turbo with me and the a/r ratio isn't posted by the company's website nor the dimensions to calculate.

 

You think since he had a V8 and their turbos are app specific mine might have difficulty turning the turbine?

 

he prolly dint have a tune. If you get a GOOD tune you should be good.

 

still curious of the effect of v8 specific application turbo on 4 cylinder use...

 

Get that out of your head now. People told me my GT3582R would be really laggy but it isn't. Our engines aren't Hondas they actually have some displacement to them. You need to find out the specs the A/R's for the impeller (compressor) and turbine (exhaust). Then we should be able to give you more info.

I heard the same damn thing on another forum about my old T3/T4b 60 a/r compressor housing 82 a/r turbin housing...worked like a charm for me

 

I know it's lower than most as it's for remote mount setup, not certain yet but others approximations appear to be about .64, someone said .34 or something, dunno where that came from... asked sts last night but haven't received a response yet so will see.

 

found out why my friend blew his engine lol didn't have boost controller installed n was running over 12 psi on stock engine lol

 

12psi on what motor? The 2AZ-FE? Our motors can handle more than that with proper parts that are installed correctly and tuned correctly.

 

no, as i said originally he had a 4.7l v8 dodge dakota

 

chris what turbo did u have ? I think we might have the same one, I have a 60 A/r cold .82 a/r hot in a t3 flange and 4 bolt exit.

 

yep i think they are the same (could have sworn i said that already...lol) t3/t4b stage 5 wheel 60 a/r cold side 82 a/r hot side

 

It's not a Honda, but it isn't a 4.7L V8 either. The engine that the turbo was from is nearly twice the size as our motor. Considering the redline is 6000RPM in the Dakota V8 and 6400 in the tC, the 4.7L is flowing about 60% more air.

Going based off the formula for finding out CFM, a stock tC flows approx 240CFM of air. A Dakota w/ a 4.7L V8 flows approx 425CFM of air.

It's highly unlikely that the efficiency range of that turbo will work for vehicles with such a different amount of airflow.

 

so are you saying it wouldn't be worth it for this turbo you think? i don't know if i'll have the money to install a properly sized/ tuned turbo til i get out of college which would be in nearly three years since i took so much time off, i finally have the turbo, with the piping but set up for the dakota so plan on getting proper fit piping. Also came with two similar devices made by tial placed on the piping. I know it's a dumb question, but wondering what these are exactly, one is blue, one is silver. the silver one is just after the turbo w/ a small outlet pipe, for boost controll? the blue one is on a piece of the piping but don't know where it originally fit, sensor or something?

 

another question on this is, I plan on obtaining a three gauge pod that comes with w/ 3 optional gauges, which would I want to put on and would wire w/o necessary extra hardware? I know boost pressure is a given but what about the other two? air/fuel ratio? maybe oil pressure for the third?

 

We still don't know what size the turbo is though.

 

I know, I'm just saying that without a turbo map, it's impossible to tell if it would work. If that turbo was mapped out for very low boost on the Dakota, it could work with high boost on the tC, but it probably won't be very efficient.

 

ok, now from my calculations, i got a .48 a/r ratio, think you guys can give me any more guidance now?
