LN Engineering posted the following on their Facebook page:
So I am just going to leave this here. I can't wait to see the mayhem these sorts of creations would make.
Planning to boost your M96 engine? Suffered cylinder damage from a rod failure? LN Engineering has solutions for both. Although we typically retain open decks, closed deck conversions are available as well as repair sleeves to save damaged Porsche blocks.

We are of the mindset that keeping these engines normally aspirated is the best thing you can do, but we still have requests from time to time for turbo conversions. In the past we would limit the bore size to 99mm for an added margin of safety, but some still want to go to the larger 101mm bore size. For those people we can do a closed deck conversion however we would still recommend open deck first.

I think if done properly the mayhem will/would be fairly limited. LNE/Bilt Racing has plenty of experience with all things M96 so if I were so inclined to insist on adding a turbo, they would be a shop I’d trust to do it. I would imagine it will be expensive…

That's pretty cool and I'd consider a boosted option if LN made the bottom assembly for it.

When I was putting together motor ideas to try to reach my power goals while keeping replacement cost down - the 2nd place option was to use turbo charged boxster motors. The boxster motors are cheap and easy install. Turbo it to make 350-400 WHP and when it blows up, just throw another cheap engine in, at the cost of the boxster motor, you could do this many, many times before approaching the cost of a high HP 911 M96 rebuild.
A very highly respected Boxster racer thought that the motors could be run up to 350HP relatively reliably.
Main reasons I am not going this route 1. turbo system complexity and heat management (not a big consideration for a street car IMO) 2. Power limitations, 350 is good but I want more.
THE replacement for displacement, I say boost away !

I mean it's idea for big boost but low boost applications and the stock(albeit high) compression wouldn't be too bad if you have access to higher octane fuels. I've been reading up on the VF Supercharger for a while now and think that's the most HP I'd consider for a 2950lb car, I kinda wish HKS or Rotex made a builder's kit for their systems. There's a company out of the Netherlands(I think) that has a Rotex kit for a 996 but very little info on them and it's extremely expensive.

We all know how the M96 can potentially fail.
1. Imsb
2. AOS
3. Bore scoring
4. Oil Starvation (track related)
5. Overheating (track related)
We now have solid fixes for each.
1. Imsb - LN retro or solution
2. AOS - UAOS
3. Bore Scoring - change your oil min 2x a year plus many other suggestions made by FSI and LN.
4. Oil Starvation - UIDS with UAOS track w/ extra quart of oil.
5. Overheating - UAOS w/ extra quart of oil, 3rd radiator, and soon to be LN oil cooling kit.
So the question is, what additional stress is put on the M96 engine with a turbo or super charger and what additional solutions are needed to mitigate the risk of grenading the engine. We also have to ask if it's worth it knowing that a rebuild may be needed sooner than later in addition to the costs of the turbo/supercharger kit.
Just thinking out loud.

Better chance of seeing 200k than any of this stuff happening (not including track which I’ll leave to the experts).
I’d be curious if they ran a new m96 motor and a 3.0/3.2 motor simultaneously under similar conditions on the road, which would give less issues over 200k with proper maintenance.
I bet we might be surprised.
I’m no car expert but I do read excellence each month and am aware that each generation of 911’s seem to have costly issues. Replacing the Imsb as a wear item doesn’t really seem that bad compared to others.

I have a weird way of looking at it. Most of us bought the car with the understanding the engine might fail, so whether it fails at X miles NA or Boosted... you're still going to have to potentially rebuild it at some point if you keep the car long enough AND drive it enough.
