One little comment I’ll add is I find the powerband and torque of the .2 to be fairly noticeable. DFI along with the extra .2 really adds a punch down low.

997.1 is port injected vs the 997.2 being DFI? Wonder how this carbon buildup will pan out when these cars get up there in mileage. My Cayenne and RS4 are relatively easy to walnut blast but for the 997.2's it's an engine removal maintenance item, if it's an actual issue.

Calling Elliot! Elliot, did you happen to take a peek at your intake valves when they had your car opened up? Wondering how the intake valves looked.

The .2 engines aren't DFI. They're both port injected.

Only the 9A1s in the Carreras and Turbos in the .2 are DFI

^ correct

You can’t go wrong with either one but I prefer the .1. I like the 997s with the older ligjts. It fits the year properly. Also, I like how the 3.6 revs and sounds (minor difference). Furthermore I think the 3.6 is a little more reliable since you don’t hear about the cam actuators backing out. Like others mentioned, buy the best you can afford.

I prefer the 997.1 design, but that's just personal bias. I think the 997.1 is slightly more old school and simple (no FAL, no CLs for instance) which I like, but you can't go wrong either way.

I can confirm. I had the same mistaken assumption that the .2 was DFI. However, upon conversation with my mechanic and inspecting my heads, it is not DFI, which is likely a blessing due to carbon buildup issues.



997.2 GT3/RS Head

I recently had opportunity to drive back-2-back, both port injected;-.... 997.1 3/RS, against 997.2 GT3. The improved torque & power was indeed noticeable by me. I also didn't find the LWFW difference to make that much a improvement,... slightly yes, but not as much of an impact as the power differential. I also prefer the .2 sound (but I'll add the RS was stock, and my .2 has SW,... but as everyone has said, it is a personal choice thing.

Great. learn something new everyday.

Thanks for the correction. Ill shut up now.....

between those will feel massive due to the 3.89 Ring and pinion. Combined with the 3.6 vs 3.8. But between reg gt3 you won’t. And throw the R&P in the 3.6 and prob feels torquier than the 3.8gt3 (non rs). Granted can do same to reg 3.8 then would be like RS.

i find the R&P makes the car feel much torquey than the 3.8.

I'd like to try out the 3.89 R&P. This has been on my list of mods for the last 8 years! It fell down the priority list when I did my 4.2 build. You ever come down to Orange County? Want to test drive each others' cars?

if I ever go down. It’s a bit of a shlep but if I do I’ll message you. Always welcome to lmk if you come up. Happy to let you check it out

This is really great to know (& to hear it multiple times, so I get it thru my thick skull).

And so if I ever get a 997.1 3/RS (which would probably be the ONLY next 911 I would ever add to my stable), the 3.89 R&P would be the first to happen,...

.... plus probably a taller Rose Passion 6th gear since I like to do a lot of touring, and sometimes those stretches of highway between the twisties need a lower rpm (supposedly so I am able to hear the wifey tell me how badly I shook her up on that last set of twists)
