wow. the misinformation (if not outright lies) that flow from the lips of stealerships never ceases to amaze. there is no DME reprogramming required.
Thank you all for your input. I think I am leaning toward not doing it. I am getting push back from the Pepe. They will not cover the engine for the two years if I install these parts. Also, they do not have the tools to reprogram the DME with the new FW, so I don't want to be pulling out and have the car stall on me every time I stop. So if anyone is interested I will be selling the clutch kit and the LWFW that I have still brand new in the box. I will post a new thread with the parts numbers and some pictures. PM me if you are interested. Thank you all this has been very helpful!!!

There was a SA from Porsche a few years back that was posted here (can find it with a search). Basically, Porsche tells dealers not to install LWFW on anything but the RS, which is the only car / engine designed to handle it. I guess there were enough failures to get Porsche to notify every dealer and of course if you install it, you void your engine warranty. Before the SA was issued, I'd think about it only if my engine / clutch / flywheel had to come out anyway. There was nothing from Porsche specifically telling us not to do it. But now, if my memory is correct, we're all on notice.

Read this thread, it got same exact info essentially. And decide for yourself.

If I understand it right LWFW with a sprung clutch should be OK.

Well, you've received plenty of advice, and so the best thing to do is what you've decided to do: go with your gut. It's your car, so you've got to be comfortable with your decision.
Each of us have a different appetite for the rsik/ reward balance. If you look at my mod list, you'll recognize that I'm out on the fringe.
Good luck with your new engine, hopefully Pepe will do a great job on the installation. And if you get the bug (as I am sure you will), come on back for more advice and friendly debate!

The LWFW conversion on the Carrera engines is much simpler due to the design.

Rep Power: 161 The RS FW Conversion Kit that Sharkwerks sells has all the right parts to make the LWFW work.

I guess it all depends of to what degree of imperfection crankshaft was produced and how it is balanced in ones car. Obviously it does not brake in each and every car with LWFW. But it would be incorrect to claim that such thing may not ever happen and as you could see from link I posted - it does happen more than once. From other perspective tracking nuts probably kill their cars way before crankshaft is able to accumulate enough stress to give way.
I am trying to work my car as hard as I can, but this car has yet to have anything go on it, incredible! The plan is to pass it on to the next owner and get a GT3 soon, and if it becomes a garage queen will likely implode!

Again, all you guys have been a great help in helping me make up my mind. This is what I have decided to do. I will let the dealer put in the new engine with the OEM parts. Then I will start doing other mods on my own like the exhaust and intake and software. I think I was discourage by the dealer and at the same time I do not trust them in installing the LWFW right. In 6 months time I will do the clutch kit with the LWFW by a 3rd party. If anyone lives in the NYC area and has the LWFW installed on their 997 I would love to meet up to get more information. Again thank you all for your help.
