The is also on the Porsche web site. It is testing the new 9A1 engine which is in the 2009 (997.2) cars.

The 3.6L motor gets a 20 HP gain, now at 345 HP, while the 3.8L motor gets 30 HP increase, which takes it up to 385 HP. Both engines red line at 7,500 RPM.

The completely new motors:

• do not have an intermediate shaft
• have 40% fewer engine components
• have the water pump is mounted outside the engine for easier service
• have a water pump th that pushes 20% more volume
• are fitted with DFI (direct fuel injection)
• do not require a secondary air-injector system like the 996 and early 997 motors
• are more fuel efficient (sorry, I don't recall the percent improvement)

with heat. No sound on my PC but even so, no guarantee sound coming from *that* engine.

Sincerely,

Just get one with a GT3 engine if you want bullet-proof.

You know its funny that everyone rants about 996 or 997 motor reliability and speak of 993 mototors as being bulletproof. I was laughing hysterically until I wrote a check for $10,500 to do a top-end due to the secondary air system getting clogged up in my 993. Granted I had a clutch, rings and a few other "motor refresh" things done but man! Laughed even harder when I heard that basically everything was in great shape inside the motor. If this is what one pays for a motor thats reliable compared to 996+ motors except for the minor detail of valve guide wear preventing one from passing smog then things are really outta whack! I heard I could've purchased a brand new 996/7 motor for that kind of money.

Pretty close. When the 996 was still in production, an engine was about $8K. Now they are running $12k to $14K.

Hey man,
Your sig begs the question....
Why U driving that fuel efficient, reliable, low maintenance mobile?

Long story, but I'll make it short!

Leased my 996 for 3 years. Best car I have EVER had. 12 months later, lost my job in a coprorate downsizing. Took me 18 months to land another job, but for 40% less than I was making previously. Moved from Charlotte, NC to Dallas, TX in February of this year for the new job.

Wait it gets better....

I found out 3 weeks ago that my last day at the "new" company is next Wednesday, Dec. 3rd. Company sold off 60% of the stores and is laying off 150+ of 185 corporate employees. Oh yeah, and we have not been able to sell our NC house. I think I may have mis-understood the American Dream about "having two incomes and one mortgage." I thought it was "two mortgages and one income."

BTW, I HATE driving the !@#$%^&* Honda!

OK, enough about me! How has your year been going?

Really?...they are not immune to RMS failures. From tthe 997 GT3 forum:

As you discovered upon teardown, SAI has nothing to do with engine reliability. 993 engines really are robust. Unfortunately those with 96 and later 993s need to be concerned with SAI issues and resulting CELs. This is not a problem with 95s.

But it not all rosy for the 993 folk - steering rack leaks and a pathetically designed LSD (shared with the early 996s) keep things interesting.

The Gen 2 997 engines are for all practical purposes entirely new sharing little with their predecessors;

quote from Edmunds;

"By the Way, an All-New Engine
Porsche's engine boffins reckon that every single component in the 911 engine has been either replaced or redesigned. There are 40 percent fewer parts and 11 pounds less. Even the bore and stroke have been slightly altered, as the Carrera engine now displaces 3,614cc and the Carrera S engine displaces 3,800cc. A new electronically regulated oil pump ensures constant oil supply under extreme cornering loads."

You have quoted a post from last year. I was not refering to the new 997.2 motors which as you mention are an all new design.

I'm lucky - my 996 (first year) had enough problems the dealer took it back before the engine could fail.

The reliability of the M97 is no more or less reliable than any other 911 engine. It still has some issues with it. Many like to cite the "bombproof" design of the 964 case which has been around forever on the 993 and GT3 997s and Turbos, but those engines have their issues, too (e.g., seals). Drivers can absolutely destroy pretty much any 911 engine and transmission through poor driving practices. These things are pretty tough but they are not infallible. We have a guy in town who races his Carrera GT and then thinks he doesn't have to put any money into it (e.g. brake pads, rotors, clutches, etc.) because it's "a race car." I got out of racing several years ago because it's just very expensive, and for me, a marginal return. If you drive them hard these cars will perform well, but you have to be prepared for something to creep up.

Compare these engines to any other make/model and the Porsche engines will be considerably more reliable. For example, I wouldn't attempt a long road trip in a Ferrari, Maser, or Aston Martin.

My '06 C2 has >47K miles on it. Zero engine, tranny, clutch, brake issues of any kind whatsoever. This car has been friggin' perfect. Additionally, zero oil leakage on the garage floor. Truly wonderful car.

Thanks guys/gals, for keeping this thread alive. I'm just now doing my homework on 997 (2006 model year C4S is my target car). If any one want to express their thoughts, I considering the C4S as a year round driver, that will see 15k to 20k a year.

I'm not new to Porsches, just be away for a few years (ok two decades).

Thanks

Mark.
