@Hunter - would certainly be interested in any more picture or context/interesting things your shop learns about the drivetrain

For this thread - I do appreciate the lengths manufacturers have taken to make turbo cars highly "driveable" where the feels is almost equal to NA engines. Great for everyday drivers and track use - no question

The only con I see for such a setup is that the turbos may not pack much punch mid-high RPM as they would if the turbos were one step larger. For example, I have an oversized turbo in my WRX (only 1-2 sizes larger, a Blouch 16G XT, not a drag-focused turbo that's huge) and I enjoy the two sides to the car: When driving around town or cruising down the highway and you're only putting the accelerator down say 30% or less, you get great fuel economy similar to a NA engine since the turbo doesn't really spool up. However, when you want to go fast, you intentionally give it more fuel and yes wait a couple seconds (you can usually plan ahead for fun times) then there's a large force that pushes you back until redline. The Stinger GT certainly has power and down low where it's highly usable, perhaps the perfect setup is a sequential turbo like the old supras had from the 90s - where you'd have a small one spin up quick for low-end fast response then a larger one to cover you at higher RPMs.

I realize most drivers would balk at "turbo lag", but I get 30mpg on avg and my car dynos similar to the stinger GT in HP (stock) to my modified 2.0L WRX so I get the best of performance and economy though I do lack low end power which is why I'm excited to have the GT. Just wish the GT wasn't 800lbs heavier than my WRX...

Exactly. The perfect set up in 2018, to me, would be a small twin scroll turbocharger for low to mid RPMs, and a large twin scroll turbocharger for mid to high RPMs...

Hunter, would you mind sharing the model of the turbo on this car please. i've been Dying to see the compressor map on this turbo and not knowing what it is makes that difficult.

 

[Hunter]

From what I see from these tiny turbos they have put on the 3.3 is for faster low end response and idk how they would be able to get any bigger turbo set up in these for the simple fact there is no room. I removed the motor today because of a blown turbo on the left bank not a customer car came from factory like this caught on the inspection but I will say from the hundreds of motors I have pulled they really made this one quite simple to do no removal of any connectors on the engine was necessary it disconnects from pcm. But if you are a do it yourself kind of person and ever have to pull the motor I will say having a support table is much needed

The model is a Honeywell A/R 61 from what I can see on the turbo

Awesome, a baby garrett. Do you think you could snap a picture of the plate on the turbo?

Here’s more pics of it

Cool, how come?

Blown turbo on the left bank from factory.

oof, that definitely ate something. Sorry to be a pain but could you get a picture of that Kia plate on the top of the first picture. I think i may have nailed down which turbo this is closest to.

Here you go

You sir are a king among men! Thanks for that. Time to go research.

@Kia Stinger would it make sense for this to be a separate thread for easy reference later on?

That's the future "GT Sport" model

The problem on a V6 (instead of a straight 6) is you'd need four turbos

Because of the twin scrolls?

 

[eflyguy]

Pretty sure you can do it with one small, one larger.. I was watching something about that the other day, although not sure it would be possible the way the Stinger is set up - I think the one I was looking at had exhaust down the center between the banks..

...it appears this motor/tranny is from an AWD model, yes?

 

[Eugene Onegin]

I'm not a gear head but I was wondering ,why don't they use one supercharger instead of twin turbos ?

Excellent post!....Please take as many pictures as you can of the engine out side (front, back, sides, etc). Close ups of turbos, pulleys, manifolds, accessories, etc. This will come in handy when we start exploring the possibility of increasing turbo size. One thing I can tell anyone looking to upgrade the turbos, is that they are going to require custom manifolds as the factory ones have provisions to bolt directly to the OEM turbos.
