Following up on my comment above, I noticed the rebuild kit LNE sells above does include Elring head gaskets (based on the photo) which it lists as "OEM/genuine" so that answers that question.
(BTW, eeuroparts.com is almost always far cheaper than FCP Euro who sells this same kit for $704. That lifetime guarantee isn't free.)
Lots of other pricey things in the LNE kit that aren't needed such as the ARP head stud kit ($500) (see edit). Not to bag on LNE as I think they are great but just pointing out for a standard rebuild you don't need all this stuff. I would definitely spring for the LNE Nikasil resleeve though which is $5500 including pistons.
I'm going to start compiling a spreadsheet on this as aside from the resleeve/piston costs, I'm thinking one can keep parts costs well below $3k by being smart regarding replacements and shopping around.
Edit: Looks like I got confused by LNE's photo as the kit I linked as OEM headbolts, not ARP. These are around $240, not $500. The ARP headbolts are in the more expensive package. Regardless, that's still a $240 savings if they can be reused as Porschetech3 contends.

When I think of time and $ invested there is no way I would consider cutting corners, especially not over $240 - even $500. To each their own though….

Cutting corners is a figure of speech (which is why I put the phrase in quotes). What I meant is doing a rebuild without paying the Porsche tax, such as using OEM parts rather than "genuine Porsche" parts whenever possible and not replacing things that aren't broken or worn. That's why I gave the example of the head bolts, even the Porsche workshop manual says it's ok to reuse them (as they aren't stretch bolts) yet everyone replaces them. I don't throw money away on stuff without a really good reason.
I realize an FSI engine is something special and I'm not knocking it (I'd love one myself). What I'm trying to do here is come up with an option for the guy who suddenly finds himself with a bore-scored engine and doesn't have the disposable income for an FSI. It's looking like you can do a DIY rebuild (including LNE Nickies) for just over $10k.
Jake is a perfectionist and God bless him for it. Not everyone can afford (or even wants) perfection, particularly if they are suddenly hit with bore scoring out of the blue.
While were waiting for more videos I figured I'd drop this here to give people something to stew on. This is a rebuild parts list for an M97/3.8 liter 997.1 (M96 is similar but not identical!). I've tried to come up with the lowest cost options I could find that are OEM or genuine Porsche.
Bottom line is that you can procure the parts needed for around $3k (provided you don't replace perfectly good parts). Couple that with Nickies/pistons/rings from LNE ($6k) and local machine shop work on the heads/crank ($1k) and you can keep this close to $10k.
Edit: Have that machine shop pin the IMS while they're at it. Need to think about what to do about the IMS bearing also. Lots of choices there ranging from doing nothing (may be okay with the big bearing) at one extreme to an IMS Solution at the other.
See the attached PDF for the parts list and costs. Here's the color coding I use on the cost column (these are my opinions):
Black: part should be replaced
Red: part may be reused if not damaged or worn excessively
Green: Other worthwhile sources shown in comments could be considered as further cost reductions
I priced these at eeuroparts.com (OEM and genuine) and porschepartsnow.com (genuine) as I generally find they have the best prices. If you shop around you may be able to get them a little cheaper but probably not by much.
Edit: Found a couple of things in the spreadsheet that I updated in a newly attached version (r1):
- Secondary AOS is quantity 2 not 1
- Valve solenoid (rear) changes mid-way through M97 build to 997-105-301-00

You are correct in that there is always more than one approach to addressing a problem and what you have put together is really good stuff that I am sure many people will use/appreciate. Sorry to come across as knocking your approach and I look for to reading more as you move through the process.

No need to apologize, it's all good. Amazing how a car creates so much passion isn't it? BTW, I've really enjoyed following your adventurers with your FSI and that's one of the reasons I wanted to make clear this wasn't viewed a knock on Jake's masterpieces (seriously, I view them as akin to a work of art). This is aimed more at the poor guy who saves up to just afford his life's dream and then starts hearing thunk-thunk.
I still wonder how they are going to be able to attach the pistons to the rods in Bank 2..... There is probably a way to do it and I wonder if it would not have been easier to install them before installing the Bank 2 case in place.
