Carbon buildup.

CAVU

With an open mind I ask, why would the DFI engine incure anymore carbon build up than and manifold injection?

Chris from Cali

It has been a big problem in DFI RS4s and BMWs (cars from 2007 or so). Unless Porsche has a magic trick, it'll get the same issue. Here's some scoop:

Sorry for the infomercial at the end. Bottom line, the first minute and a half are truth.

The 997.2 Porsche has been out since 2009 and I did significant research with not one Carbon issue to be found, just because Audi or BMW has it does not mean anything.

Your comment has nothing what so ever to back it up, the IMS/RMS has plenty.

CAVU

I appreciate your sharing the source of your opinion. We'll have to agree to disagree on this one. For me, it's an infomercial from the start until I see something presented that's independent with data from repeatable testing.

Cheers.

That's a little bit too general to recommend.
I have a 997.2 C2S and wouldn't want a 997.1. I think generally you might find some 997.1 owners who might recommend a 997.2 - not so sure you'll find the opposite.
The one downside of the 997.2 I can think of is exhaust note. That's an as remedy though with more value options; X-over, Fister mod, or going cat-back exhaust such as Tubi or others (I went Tubi and the only issue with cost I have s not doing it earlier).
Then there is always the $$$. All things being equalt - I'd rather have a 997.2 with 50k than a 997.1 with 35k assuming equal sale price.

Really? So a negative response counts as a positive result? The carbon buildup (as I noted) came on cars from as far back as 2007. It takes a little time (not overnight). I've seen a ton of photos and stories from friends about the buildup in their heads from the DFI. As I mentioned, unless Porsche is doing something differently, it's bound to happen. It's a function of how it works. The fuel doesn't have a chance to clean off the valves since it's sprayed directly into the combustion chamber.

Important part for the tl;dr crowd:
I'm really not an idiot, and I don't hate DFI. I owned a 2009 C4S, a couple of DFI GTIs, and a DFI Golf R. It has a ton of advantages. I just didn't want to deal with the high-pressure injectors and carbon buildup 20-30 years from now (my 997 is a keeper). I hope this helps "back it up".

Porsche took almost 10 years to develop a completely new engine for the 997.2. They are also using this engine now in the turbo something they did not do with the old design. Either you think Porsche knows what they are doing or you don't. If you don't why own one? My bet is they did a **** load of testing and this is one strong engine and a big improvement over the old one used in the 997.1 and 996. I would spend the extra money and go with the 997.2 in a heart beat.

I have one of each: 2005 S Cab, and 2009 S Cab. Both have been utterly reliable. No concerns about either one being out of warranty, but then I'm the original owner, so I know the car's history. Never a problem, most reliable brand of car I own.

There's always improvement and technological advancement. The 2009 has more power, much better electronics (Bluetooth, touch screen PCM, iPod interface, sat radio with traffic information), but I enjoy them equally.

You state that you are trying to swing a .2 if you can 'get to it financially' -- there's not that much of a difference in prices often and if that is what can break the bank maybe a 997 is not for you. You must be prepared to put decent tires on it and maintain it to avoid issues down the road.

I really like the .2 The exterior update is fresh and the PCM is improved for the gadgets.
More importantly, there is a nice performance boost and the .2 S is one fast car. PDK would be the best reason to opt for the .2

That said, the 997.1 is a real bargain now and it's a great car. It's really a question if $10 to $15k more for a newer .2 is worth it. Drive both!!

For me it wasn't and I found a great 997.1S (knock on wood). If I change my mind, I'll just get a .2 with no regrets.

I don't think you can go wrong with either version if its been taken care of.

I would probable go with a 997.2 non s version instead of the 997.1 S. If price is a deciding factor. They are both about the same hp and you get the newer more reliable motor and electronics.

No need for CPO. Just get a PPI from a reputable shop. You are just prepaying anyway -upfront. That's my two cents.

I'm in the same boat with my search. Was on the .1 C2S vs. .2 C2 fence. Almost immediately after the first of the year, the prices seemed to drop a little more and a number of .2 C2S cars and are now out there in the $62-58k range and continuing to dip down. Figure since it's winter I'll keep searching a little longer, get a few more lease return 2009's in, more 991's on the road, etc. Anyway, I'm thinking .2 C2S now for sure. Only thing I could see changing that is if I found an 06-08 low mile car in the low $40's...but currently most are smoking crack on their .1 inventory prices.
