Those that have new S & 4S cars w/ PDK don't seem to complain about lack of power at all.

Don't order the X51. Just get the regular set-up w/ PDK. I imagine it will be more than you will ever need, and you will love it to death.

If you really want to spend 12 grand on a worthwhile upgrade, buy me a supercharger! jk

What's the power output of those bad boys anyway?

435hp!

Ok, so here's what happened. I called up my dealer to tell him I may be interested in getting the X51 package on my C4S build. He called me crazy a few times, as the sticker for the car was over $150k, and told me he'd call me back in a few minutes. He called up Atlanta for me, and apparently, they have confirmed that the MY2010 911 Turbo will have the Tip replaced with PDK. I removed my deposit for the C4S and placed it on a Turbo. The car is a November build with a December delivery. Guides aren't out yet, so in a few weeks, when they do come out, I'll option it out and go from there. I think I'm going to be much happier this way - I get a car thats a model up for the same price, you can't beat that. Thanks to everyone for your help.

Good move. A turbo with PDK will be an incredible car.

Ask your dealer what engine is in the new turbo and how much hp.

Keith with the 997.1 S the X51 kit doesn't include camshafts..stock cams are in the 997.1S X51 kit.

Now there's material for daydreamers.

Dreaming you had crazy money and swapping out your new engine when your plush ordered new S arrives with a GT3 engine that you order to arrive about the same time your new car does.

I am really confused? With the 997.2 C4S, there currently is no X51 kit available. In fact, the new 997.2 S models make more HP and torque than the 997.1 X51. In fact, you would have basically been screwed if you had ordered an 08' X51 when the 09's came out as you would have paid an additional $17K for less performance.

Not quite true. Recently Porsche announced the latest X51 offering for the 997.2 cars.

10 GT3

First, the 997.2 GT3 isn't even out yet. Dealers just got their allocation counts, so we will say that is...unlikely. Second, a new GT3 engine is around $30K from Porsche parts, not including the ECU or wiring harness. You will also need a GT3 G50 6-sp to replace the Japanese sourced weaker box. So after doing all this (over $40K worth of upgrades) you slightly less straightline performance as a GT3 in a Carrera chassis as the Carrera chassis is heavier than a GT3 chassis.

Now look at upgrading the suspension to adjustable coilovers with camber plates, adjustable sway bars, adjustable control arms and monoballs on the lower pickup points; all of which the 997.2 GT3 come with. That is only another $6-7K. Go further and upgrade the brakes to 997.1 PCCBs to get braking similar to a 997.2 GT3. Figure $5-6k for this upgrade with steel rotors. The 2010 GT3 uses the same diameter brakes disks and as the 997.1 GT3 PCCB kit standard. It even comes with floating rotors standard. PCCBs is now literally just a rotor material upgrade. Finally, spend another $7K on and aerokit (of course standard on a GT3).

So what does this give you? Close to GT3 performance in something that is not a GT3. Bottom line is stop dreaming and get the complete package: a GT3.

10 GT3

I just research and this is what I found:

Price is 12K Euros.

So the changes are reduced with no longer upgraded cams and headers as previous X51 options. Price is similar to 997.1 for Euro version so US should be in a similar $15K range. Sounds like milled or ported heads, intake system and sports exhaust. Given the power increase from aftermarket dual filter intake kits and primary muffler bypasses, I would skip the power kit.

X51 and PDK will be an awesome combination, different from a GT3 and suiting a different purpose.

Having owned a 996 X51 and being sufficiently impressed (actually my wife wanted it, after doing PSDS) with it to buy a 997 X51 which I owned alongside a GTX car, I can tell you the X51 is a very misunderstood package; easily dismissed by those who know "the price of everything and the value of nothing". If you are going to trade the car quickly, the X51 is expensive but if you keep the car awhile, it is worth the money.

I expect the new X51 will continue the tradition and be surprised if it doesn't, it will be awesome on the track too, and have the advantage over the GT3 by being a daily driver. Of course, it is in no way as hardcore as a GT3.

I was totally disappointed in my 996 X51, I felt no difference what so ever vs the stock, but then again, how much are you going to feel with a power upgrade of 25 hp?

kdurg

Maybe you're right.

BUT according to Excellence--February 2006. Page 57. Discussing the X51 Power Kit....

" revised cylinder heads, new exhaust headers, camshafts with more aggressive profiles, a different Varioram intake plenum and new Bosch Motronic engine management............."
