997.1 vs 997.2 and the "big difference"?
For some reason, lately I have been reading various threads that mention how much better the 997.2 is than the 997.1. Mostly the:
updated/improved media (navi, phone and MP3 connectivity, etc…)
Updated looks (rear lights and front grill?)
Interior?
MOTOR the DFI vs the standard motor on the 997.1.
Frankly I couldn’t care less about 1-3. I actually think the 997.1 looks better (especially the rear lights, but this is of course very subjective). I don’t worry too much about Navi (I use my phone) or stereo quality (the motor is my stereo, and I have a real stereo at home. The last 3 cars I have owned, 350Z and M3 I had put several thousand into the stereos, but frankly, I don’t care that much any more). And interior? Not a big deal to me.
Oh, I almost forgot about the SPASM vs PASM, so that is an improvement I would guess.
That gets me to the standard motor vs the newer DFI motor. I am guessing the “upgrade” is that there are 30 extra horses under the hood (thats great, but surprised the 0-60 and ¼ times are more significantly different, although the trap speed is showing a pretty good difference). The other “huge” difference is the non-IMS in the DFI motor and the reliability potential with one failing. So what if you happen to get a 997.1 and have a warranty and/or you do the IMS solution. Does this make the “significant difference” between the 997.2 and 997.1 not as great? I actually prefer the sound of the 997.1, but the 30 extra HP is always a good thing.
so is the "big difference" an accumulation of a lot of little things or some major thing that I am missing?

Except for early 2005, the IMS is not an issue. I have not spent any time in a 997.1. Went from a 996.1 six speed to a 997.2 PDK. Both C4 cabs. And honestly can't tell a difference in speed. No track time, just driving. The place I can tell a difference is the gas pump. Much better mileage in the 997.2-if that's important to you. I drive a lot so I spend less time at the gas station.

One downside to any DFI engine is carbon build up that traditional fuel injected engines don't suffer.
Many if not all DFI engines will have to have that crud cleaned out. Some need it every 15K miles, like some Audi cars I've seen. Others, it could take far longer. It's seldom talked about, and it's not cheap. With Porsche and it's usual pricing, I would expect this will be a costly expense when that times comes.

The placement of the injection in the 9A1 motor prevents this...
The 9A1 is not an Audi DFI

To the OP: DFI engine is no small change. It is a totally new block. I also know from replacing the shocks in my 2009 C2S there are suspension differences. Nobody seemed to write about them but the car configuration in the rears is different. Did Porsche do this to fit the new engine or did they improve the system? I dunno, but there are more substantive differences than just the block.

997.2 is dry dumped for track use. 997.1 is not. Cylinder scoring and oiling issues in 997.1. There are a lot less parts in the DFI motor and no IMS. Improved engine design and power. Nice interior refinements and led exterior lights standard. Still like the 997.1 but I am glad I purchased a 997.2S. Fantastic car.

You mean like the IMS issue on the 996/997 and the weak valve guides on the 993? Glad to know there aren't known issues with carbon on the 997, but...
More like, leave it to Porsche to hide any evidence until it becomes impossible to ignore.
Then again, Porsche is now owned by VW, and VW would never lie.
Right?

Porsche tends to upgrade their cars in small increments, and this is especially true of the 911.
I feel that the 997.2 is an incremental improvement over the 997.1 in some ways, but it's not a dramatic change. I think that the way you view the differences depends largely on the things you prioritize. If you want an automatic transmission, then I feel that the PDK transmission is a nice upgrade. If you want upgraded LED lighting, then the 997.2 is a nice upgrade. Little things like ventilated seats and center lock wheels are nice. The headlights are a little better on the 997.2. To many people, the black plastic on the 997.2 center stack looks better than the gray plastic on the 997.1. Are any of these things dramatic upgrades? No. But they are nice. I don't feel that the 997.2 is a "totally different car" than the 997.1 as you sometimes see posted here on the boards; it's a slight improvement. Time moves on. Things get better.
All the 997 cars are good.

You listed all the major changes, and they are major. But you dismissed them. And then want to know what you are missing. Perspective I'd say. To me it sounds like you are just trying to convince yourself that your 997.1 is just as good. Not saying it's not, but the improvements made do matter to a lot of people. Especially the audio/nav system.
Much as it pains me to say, I'm with quadcammer I think lol

For those with MY06-08 intermediate shafts that cannot have their bearings replaced, we recommend to remove the grease seal from the existing ball bearing, which allows for engine oil to lubricate the bearing, but only when doing another procedure like a clutch, flywheel, or rear main seal replacement. However, this bearing is still problematic and should be upgraded anytime the engine is apart or if replacing the intermediate shaft with a new replacement shaft.
