well i wasnt really looking for a turbo yet for the 3.4 but one of my friends has a srt4 turbo outtve an 03 neon that hes gonna get rid of with an intercooler...i havent looked at it yet but what do you guys think about me using that on my engine?

 

Can you get the specs?

I believe it's a Mitsubishi turbo, and will most likely be too small for the 3.4.

 

Unless the car is totalled or majorly trashed, he would be kinda stupid to sell just the turbo and intercooler.

Now if hes upgrading, thats another story.

 

im hoping someone will chim in with the specs i dont know them, probably will look for them lata on....im betting it will be to small as well but wanted to ask

he got it for his neon but isnt gonna use it anymore, it was a custom set up he was working on so he kinda got it off someone who was upgrading

I believe the turbo is actually integrated into the exhaust manifold on those cars. It is on the PT Cruiser turbo and those have the same engine except for the intake manifold. I'm about 93.2% sure about this.

 

From what I remember they are a proprietary exhaust flange, (NON standard style)
Factory they are equal to a medium T3 Garret.
Also they are from a 2.4L and only do low 200/230ish on it.
So you are adding 1L and pushing the operational range way low in the RPM band. Meaning you will build boost and overpower it (go way out of its' Eff. range) much faster.

A good choice? I would not reccomend it.

and ^mike, they are not intigrated, they are bolted on. But the flange style is non standard like I said above. Meaning it (the turbo exhaust mount) will need to be custom made.

 

I just looked on evilBay and found this:

The turbine housing is integrated.

 

well I stand corrected. The pics I had seen they were bolted in.

 

Well, Six_Shooter has already confirmed that it is in fact integrated, but let me also correct you (sorry man, sorry!) that, although they only make 240HP from the factory the turbo is good for just over 300HP. The Mopar Stage kits keep the same turbo until you get to Stage 3, then the turbo/manifold is swapped out (along with some other bits). I have the same setup on my PT Cruiser with Stage 1 and I'm making about 260HP and 280lb-ft of torque and running 14.4 in the 1/4.

 

yeah i looked at it again and with the pictures it is integrated....just wondered if it would work seeing as i could get it easy...ill keep on the look out for a diffrent turbo

 

no correcting needed. I listed factory numbers.
Sure you can put a different WG spring and get more boost.

But that does not change the fact that the turbo is undersized for a 3.4...

 

How much boost can you safely run in a 3.4 without building the internals? I know I can hold 15psi with my very modest setup and will soon be holding closer to 18psi with a future mod. I know that on my car I'm getting plenty of fuel up to 20-21psi. Knowing all that are you sure this turbo couldn't feed a 3.4 enough boost to achieve what most people would be looking for? I know you don't boost this high with an engine not designed for it, so I'm just asking. I am more than willing to concede that you may well know a crapload more about this stuff than I do!

 

It is not the amount of boost you can build, it is the amount you can do while still staying in the turbo's eff. range.
While yes you maybe able to get the wanted boost level from that turbo, but at what cost performance wise? I will say that most mitsu style factory turbos have a very narrow "good" range. Knowing this you may get that Boost, but only be in the 40% eff. range of the turbo. Meaning it is heating to air so much, that you would have to do some of the following...
Have an enormous intercooler, a VERY large wastegate(extrenal perferred), water injection, CO2 spray bar on intercooler, water spray bar on intercooler something to get the intake temps to something reasonable. And yes, guys have also even hooked the evaporator core from the A/C to their intercooler.

This is where researching flow maps and turbo sizing comes in.
The standard Garret T3 style has 4-5 different hot(exhaust side) sizes, and even more Cold (intake) sizes, due to the fact you can make a Hybrid and use T4 compressors on them. Which is what most small displacement guys do. As the smaller exhaust side means quick spool up, and the very large compressor means that the turbo will have a very large, very good and broad Eff. range.
The fact that they are probly making too much exhaust pressure, which would normally push the turbo out of the eff. range, the broadness and pure size of the compressor side keeps it "o.k.", though you decrease the turbo's lifespan by doing it.

 

anyone know what the size of the stock intercooler is on the srt4....could go ahead and maybe use that though

 

I just happen to have one here, the Core measres 6" x 3" x 23"

The end tanks are a bitch to try and use though, I have cut them off and will be buidling new ones.

 

hmm...what did you pay for yours?

also any pics of it?

 

If trying to Turbo the six, why not look into a 16G or 20G from Mitsu? I mention this as look what some of the Eclipse/Lancer guys are pushing with thier 2.0 I4's. 3-400? I know the Forced Performance Lancer was pushing over 800, but I cant remember if it was a 20G or not.....

That being said, how hard is it to add Forced Induction to these cars? I ask as I am selling my Dodge Stealth next weekend to ickup a 86 Camaro with a 2.8 v-6. at least that is what I was told is in it. Ill find out on Monday when I go drive the darn ting.
