Hmmmm! Just thought I'd see what people thought about adding turbos to a 2015 Natural Aspired (N/A) GTS. From what I know the 970.2 GTS and the Turbo are almost identical except for the turbos. The Turbo S I know has lager turbos and the engines internals are stronger. I love my GTS, it sound waaaaay more aggressive than the Turbo, Turbo S and any of the other Panameras. It just seems more restrictive than it should be. So I was think about it, and the 970.2s (2015 and 2016s) have 443hp. While the 971 (2017 - 2020) has 450hp and the 2020 has 480hp. These are modest increases given the second generation GTSs are 4.0 engines and have Twin Turbos. So I was thinking, down the line that if I wanted to experiment it would be at easy as bolting on factory turbos, manifold and intercooler from the same year and with a modest tune, getting 550 would be easy.

Has anyone tried this or have heard of someone doing this before.

 

Buy a turbo if that's what you want , GTS will sell better if left original . I find it hard to believe you find the GTS underpowered ? In sport plus my 16 GTS is super fast !

 

Oooh! My GTS is plenty quick and it the exact model and spec'd out exactly to what I have ever want or found! But there is someting really interesting to me to have a "one of a kind" 970.2 4.8ltr -V8 GTS twin-turbo. I think it'll be smoother than the 971 (4.0 V8s). Those with turbos or newer years stop me all the time thinking that mods are done to the car. IT IS 100% stock engine and exhaust.... Hmmmm.

 

There are many changes made to a turbo charged car beyond adding the turbo. Cooling, fuel, exhaust, transmission tuning, drive train component strength, brakes, and the list goes on. I once turbo charged a NA Porsche. I now appreciate the engineering involved, and the right answer is if you want a turbo, buy a turbo. It is the cheaper and more reliable option.

 

if you ever play with cars like honda and subaru and other, you would know it is a terrible idea to boost a high compression car. you just going to boost like 5 psi. If you want a turbo like what people say, go buy a 971 or a turbo one. Otherwise it isn't the same, you going to have to rebuild the motor as low compression motor first and then add the turbo and then tune it, you can't just add it and thinking it will make power, if anything you going to blow up the motor and the car going to run too rich and lose power

 

Ya you forgot the low compression motor vs high compression motor, it isn't just bolting onto it. It is like those honda boys where they add a turbo onto their civic with out a low end rebuild and it run like Crap

 

970 GTS NA engines have 12.5 to 1 compression ratio. Adding a turbo is a recipe for a blown engine, GTS is a monster from 4,000 RPM to redline. No need for turbos. If you need low rpm torque get a 971 but be prepared for loss of character. PDK in my 2021 GTS feels like a conventional automatic transmission. Slow shifts compared to 970 and it feels like a small
motor in a heavy chassis.

you are sitting on gold with that motor and don’t realize it.

 

Not sure how many cars you have modded, but it's never cheap and it always snowballs. Combine that with the fact that you want to mod a 9 year old Porsche and you're really playing with fire. Maybe try a tune? Other than that just sell it and buy a faster model.

 

I think the reason you say that the 970 have more character cause the pdk wasn’t tune refine. The 971 is more refine that is why you don’t feel those sharp shift, but I guess if you drive it in manual it should be the same anyway. But it feel more like automatic cause it was tuned that way. My old f80 dct felt really raw until you tune it more refine which drive like a conventional auto too after that. That is what people want if they are driving it daily anyway

 

The 971 PDK is a vast and improvement from a dead stop but I prefer the firm and fast shifts on the 970. As you say, it feels like a conventional automatic in regular driving. Might be an engineering achievement but it is not special to me anymore. This will make the transition to electric drive easier for me.
