One key is controlling the "while were in there" impulse, and the urge to replace good parts (like lifters).
Replace known problematic/high wear areas, particularly those

Well really, the car would have been down for a long time with my busy schedule and I wanted it running faster than that..

Also check out the "997 Dad" youtube series where he documents a 997.1 rebuild using LN Engineering Nickies.

Whole-heartedly agree with the suggestion to check out LN Engineering and also a few of the great threads here documenting a rebuild using their stuff.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Enjoy while the full video is still up!
tl;dw - 35 minutes of Brewer massively bloviating about his minor cosmetic improvements and 10 min of Elvis doing Hartage cylinder sleeve upgrade to the engine (i.e., the TRUE value proposition)
3500 UK pounds (about 4500 USD) for the new fixed engine block and parts (new Nikasil sleeves, pistons and bearings)
This bore scoring issue wouldn't be such a disaster if we mere mortals would be able to get even remotely the same deal. Of course what's missing is the labour cost but still.
If someone figures out a way to bring down the costs of that rebuild operation that would be an enormous favor to the 996/997 community.
ps. Check 24.27 mark - "new crankshaft"... new? Really new and was that included in the price as well?
If you are looking for costs in the US, go to LN Engineering website. They outline the individual costs of each process or the cost of the entire rebuild. Plethora of info on their site.
If you are looking for more info on what Hartech does in detail, go to Zbombs Oil Pressure Instability thread. You can hear first hand from Barry Hart on everything he does with a rebuild and why. The video didn't do the rebuild process any justice. Hartech also produced a series of whitepapers that are referenced within the Oil Instability Thread and you can find them online. Barry shared so much information in this thread that he was banned from Rennlist. Go figure.
I stopped watching Wheeler Dealers after the second season with Ant. They did a 996 cab I believe and put the IMS solution
Brewer looks like hes had a few more brews
This sums up why alternative not-for-profit boards have popped up. Baz was one of the most informative posters on this site but was banned presumably because he's in the business and didn't pay to be a sponsor. So folks that are really knowledgeable through experience, and want to share their knowledge with us, have to pay for the privilege to do so. Something really short-sighted about that, particularly when that info brings eyeballs to Rennlist.
Whole-heartedly agree with the suggestion to check out LN Engineering and also a few of the great threads here documenting a rebuild using their stuff. The white papers from Charles at LNE and Baz Hart are required reading for anyone that wants to really understand this issue and the best options going forward. Also check out the "997 Dad" youtube series where he documents a 997.1 rebuild using LN Engineering Nickies. He's not the most riveting presenter but does a good job documenting the process.
Just skimmed through the Wheeler Dealer episode and the good Hartech stuff starts at 16:40. Nice to see the whole process and the costs quoted seem realistic to me when factoring in the exchange rate. LN Engineering lists $5375 for a Nikasil cylinder reline including pistons and accessories (without shipping).

I think people have gotten so used to seeing Flat Six rebuild quotes of $25 - $30k that they don't realize a high quality DIY rebuild can be done on a much smaller budget. One key is controlling the "while were in there" impulse, and the urge to replace good parts (like lifters). Focus on replacing the known problematic/high wear areas, particularly those that require splitting the case. Being judicious and shopping around for OE parts can keep a near-bulletproof DIY rebuild in the $12-$15k range. It's a lot of work but I'm surprised more folks don't go this route.
100% on point there. Rebuilding an engine does require a particular kind of person to do it right, even with directions. Given that an AOS replacement causes a major challenge to some, rebuilding an engine DIY can definitely be out of the question - which is fine. In that case, labor will add a good chunk of cost bringing you closer to that 20k marker. With that, I think it can be done and I enjoyed following the Man in a small garage YouTube story of the rebuild.
Absolutely, if you have the skills to rebuild, you can get just about everything you need for the rebuild thru LN Engineering. With the exception of going to Hoffman for head work and auxiliary parts such as exhaust, etc., through the other standard parts suppliers. And you can get the videos from FSI.
The question is do you want to do it yourself or pay an expert to do it which is always more. Nothing wrong with either.
Well, thanks @TRLBRAKER that's 42 minutes of my life I'll never get back! But seriously, it was interesting to see. Still have to laugh when these automotive and real estate shows calculate their "profits". Where can we find a seriously talented tech who will work for free!
Besides skills it's also about time. When my IMSB let go, I just didn't have the time to do it. Well really, the car would have been down for a long time with my busy schedule and I wanted it running faster than that.. I elected to go The LN route and have them rebuild my motor. Other than the AOS everything has been taken care of. I will take care of this next year with the UAOS.
Excellent point. I think we should somehow see much more DIYers doing this publicly which would "soften" this generic thought about bore scoring in general - not sure If I'm the only one but when I see bore scoring that equals to 20k expense.
Bore scoring is not just our engines, there are a ton of different cars out there with similar issues, mostly the new DI system cars.
Wear items like bore scoring, typically increase based on age and mileage, if there were a magic wand to find out every single engine that bore scored from Porsche I'd expect to see it start somewhere down in the 1% range first 15-20K miles, then you should see the graph trend slowly upward with occasional bumps as other contributing parts increase the occurrence rate. For instance failing injectors are very related to scored bores and bottom end issues on most all modern motors.
Well maintained cars pull the graph lower, poorly maintained cars higher. Doesn't seem to surprising.
If you start out with total engines, then over time if you assume a consistent rate of failure(All causes not just bore scoring), eventually 100% of the cars will fail..
The catch is,, how consistent is it?
I hate statistics.. LOL my 2003 died because of the failed AOS. so does the cracked cylinder count as a bad cylinder if it was hyrdolocked by oil?
