Buy the GTR. If you don't like it, I'll trade you my C63 for it!

You definitely owe it to yourself to look at a 997 turbo. I have driven neither, but they are compared as often as the M3 and C63 so it just makes sense to give it a good look. Either way you're in for an exciting car. Congrats!

I think I have a unique perspective here, since I've driven stock and tuned versions of both cars on the street and on several tracks (drag strip and road course) as well as road trips (3 hrs. each way in a Switzer tuned GTR and more in a RENNtech 63).

That said, they're very different cars. The C63 is a tail-sliding muscle car, the GTR is every bit the numb, robotic experience you've read about. It is brutally fast, and I doubt the best drivers I've been around (Shane Lewis, Tommy Kendall, etc.) in the C63 could catch me (I can't drive for s***) in a GTR on a road course.

If you want to have fun and enjoy/scare yourself: C63. If you want to break track records: GTR.

Again: several 997 TT at Switzer, and all I can say is that the car was a major disappointment. Wouldn't consider a P-car after spending time in the GTR.

So u saying a Switzer p800 997 turbo gets beat on by a Switzer p800 GTR?

what about the new pdks? they have some wicked numbers with them now

Speedriven1

Not in a straight line, but everywhere else? Yes.

Also: the new PDKs can't handle the big power that the early cars (2007-09) can. The 996 TT and 997.1 TT engines were derived from the GT1 block, whereas the "new" PDK motor is a corporate 6, with more in common (per Switzer) with the Boxster than any of the GT units.

PDK is le fail. Fast in stock form, but not up to serious modding without significant internal upgrades, and - even then - the case might let you down. tym even bought a PDK development car while I was there, but looked into it and eventually just sold it: wasn't worth developing a package on.

Zod

How is it that the GTR gear boxes can handle moding then?
or are they upgraded?
i ask as the car has sparked some interest for me

Thanks

I would probably consider a used 997 GT3 for under 100k...

GT-R + P1000 =

Speedriven1

P800 is the highest hp level Switzer offers with the factory trans. TQ is limited electronically to keep the trans. together, and the linear power curve limits the load on the gears (stays within 5% load between up shifts).

The PDK issue isn't the trans., it's the cheaper engine internals. Porsche really pulled a fast one.

Speedriven1

No P1000 kit, R1K. P = pump gas, R = race gas. R1000 kit makes about 800 on pump.

JamE55

That's what i meant. It's funny because the R1K cost as much as a used GT-R. lol!

Speedriven1

The same can be said of lots of tuning packages. Look at it another way: you're 65k into the car, and 65k into the R1K ... but what else can run with that car?

JamE55

Very true. What's a good year to do these types of packages on? 09? 10?

Speedriven1

I'd go for an '09.

I like the GTR but as far as the sound of the exhaust goes, the C63 is one of the all time greats! Also a tuned C63 is very, very fast. That said a tuned GTR is a psycho with headlights!

c32AMG-DTM

I'd vote R35 GT-R as well. Switzer and AMS both make extremely impressive, brutally quick/fast upgrade packages for that car.

Speeddriven - when you're referring to the 997TTs that were disappointing, are you including 997.1TTs like their Sledgehammer development car, and any of their R911 cars?

Speedriven1

Yes, I am.

vcruiser

Thanks for all the input!

I won't be tuning the GTR if i get that. I'd only put on an aggressive sounding exhaust and the rest would be cosmetic upgrades and a well done custom leather interior.

Also, it would be a used GTR, probably an 09 around the 65k-70k price range, so a 997 turbo is definitely out of the question.

I'd suggest you stop speaking about things you have absolutely no clue about

Speedriven: just a perspective that Dad's C63 at the same event in Miami in March ran 182mph.
That seems to be the same as that P800. And the sound of his car compared to that P800 is like apples and oranges.
I am not debating that that GTR P800 would spank the C63 in any other event.

Speedriven1

That P800 ran 191 and 194 (GPS) on all-season tires, 93 octane pump gas, and a slipping clutch. According to the "radar gun" the car was a bit quicker, but I'm not sure those guys knew what they were doing. The P800s (2 cars, again on pump gas tunes) ran 194-195 at other events later that year.

In any event, hardly comparable cars, IMO. My understanding was that Dad's car was running race gas, and I know it was taped up and running superior tires, so it was coming out of the box harder.

That doesn't take anything away from Dad's C63 or the C63 in general. Stock to stock I'd take the C63, and even tuned I would rather own the Benz ... just sayin' the P800 would rock the C63 on just about any track. That's life.

emericr

I stand corrected. I just watched the video you linked and it stated the car ran 180ish.
I agree with you that both cars stock or tuned are not comparable.
If you want bragging rights for being the fastest, then the GTR is your weapon.
I personally prefer the C63 because it is more fun and I sometimes need to carry more than 2 adults.
The fun factor of the C is not negligible either. Powersliding through corners is so much fun and probably the reason why so many of us change tires every 5K miles.

Get the new gt500, install a kenne belle 4.0 blower upgrade and expect around 800rwhp and 9 sec 1/4 mile times for half the cost.
