Question Detuning A Carrera S/GTS To Feel Like A Base Carrera Engine

I see a lot of arguments on here about comparing the engine in a GTS vs regular S. My understanding is that the engine and all powertrain components are the same but that the GTS engine builds more power (boost).

Additionally there seems to be just as much love towards the base Carrera engine which actually has smaller turbos than the S/GTS variants: twin *49*-millimeter compressors and a *45*-mm turbine wheels vs *55*-/*48*-mm units in the S/GTS. However I believe that powertrain wise that is all that differs from the S/GTS. Both engines have variable geometry turbochargers, as far as I can research!

Question: If tuned correctly could one get the S/GTS engines to feel very close to to the engine in the Base Carrera?! Food for thought! If (a big if!) such a tune existed it would make the case for buying a base Carrera only one of economics.

STATED ANOTHER WAY: You could transform a Carrera S into a Carrera T (engine wise) and have the option to go back whenever you wanted.

My initial thought is that it *might be possible*, albeit the larger turbos might still add some very minor lag. Even though the turbos are larger there would be less boost to build and the variable geometry could be recalibrated for a different RPM range. If there were differences I think most people would not be able to notice.

If the above is true, would any of you be interested (hypothetical)?

TO CLARIFY: You can find lots of threads here about how the base 911 engine is the one to have (vs. S/GTS) but the base cars are missing key ingredients (RAS, SPASM, PDCC) etc... Could a Carrera S be tuned to be a Carrera T with the option to go back to the normal S variant whenever you want?

NOT SELLING ANYTHING 🙄

I'll take your money to make your car slower, I can make that map happen.

Apologies, I must be misunderstanding your question. Would I be interested in de-tuning my 992S to feel like a base 992? No, I would not be interested in that.

Um ... isn't it already? I can't figure out what you're on about to be honest. You're not going to find many (if any) takers for your detune.

Hitting the bottle (or bong) a bit early this morning?

Why would anyone pay a premium for a car with more power, and then pay more money to make it like a base 911? One of more interesting questions I've seen on this board. And that's saying something.

This forum has gone insane. I am a relatively poor member of this community. Is this what happens to rich folk? They just lose their minds? There's been a few threads and posts that has me really scratching my head lately... like the one from a guy who waited over a year from a 4S targa allocation then passed up a 4S targa GTS allocation at MSRP... or the one where the guy wants more torque in the lower RPM range... but refuses to downshift. No. He wants to drive in 8th gear and be able to floor it and make the car accelerate like a bat out of hell from 2000 RPM or something. And now this last one takes the cake. Sofa King crazy.

No... and if you really want a car that feels slow, just drive in wet mode 100% of the time. No need for any detune.

Sorry, I clearly didn't make it clear! I own a Carrera S but like the idea of a Carrera T (but only because of the engine). Could a detune on a Carrera S effectively make it into a T (minus the price tag)?!

A Carrera T is not special because it's slower than an S. It's special b/c it has other cool parts on it like a lower final drive ratio (which actually makes it quicker than a base carrera) and other cool parts like carbon buckets, unique interior, sport exhaust, rear wheel steering, torque vectoring, mechanical diff, nylon pull door handles, etc.

A detuned Carrera S would make it a very expensive base Carrera with probably a tiny bit more turbo lag.

Judging by the harsh responses I might have and seem to not remember!

Thats an interesting point!!! My argument is that going up in trim levels (base -> S -> GTS) is more about having access to more options rather than more power. S -> GTS power increase is minimal. I would argue the fact that the GTS has exclusive options is what gets people to pay more (same logic applies to base -> S).

Without a doubt that the EXPERIENCE between a base, S and GTS is different (and arguably better). However is the increase in power a major factor for the difference in experience?! My hunch: NO.

Apologies for the confusing thread!

Good point but thats the thing: Most of the options you listed can be had on an S (except for carbon seats + nylon pull handles). If speced the same, the price difference would be minimal (I'm guessing <5%). If so, it makes getting a Carrera T kinda pointless, since with a detuned S you retain the option of easily cranking up the power and thats likely worth more than 5% over a base Carrera engine.
