So… The pristine 2005 Carrera S is without a motor. Something happened to it the other days we were just sitting at a traffic light and they found metal shavings in the oil filter. Porsche isn’t allowed to take the engine apart. They just replace them And I’m not about to spend $50,000 to have a new one put in… Even car didn’t even cost that lol
so I used to build and race Honda a long time ago. I built a few engines, modified cars heavily over the years and am considering taking on my own engine rebuild/replacement.
Just wondered thoughts on this? Anyone ever do this? Unfortunately I don’t have a gaping hole to pull the engine out of like an old civic but… I guess it is what it is.
guess I’m going to be taking the wall out of the back of the garage into the workshop after all lol.
thanks so much for any feedback on this.

Sorry to hear about this.
I've done the homebrew rebuild. My car (2007) came to me skipping at idle and it failed leakdown. I think the PO used crappy oil and/or never changed it and the rings got gummed up. No scoring.
I borrowed the tools, some knowledge, and some documentation from a forum member, and I found a good machine shop locally. Heads freshened, sleeves installed and pieces back to me in a few months.
I took my time and put it all together over a couple months. Also went from 3.6 to 3.8, which is nice (if you're gonna spend the money anyway...)
That was 3 or 4 years ago, and the car runs great.
My background is that I worked on cars professionally for a few years just out of college. No formal training though. "Retired" to hobby status in the 1990's. I also have a decent shop for a DIY'er.
One of the unexpected perks is that I can tell people that I changed my IMSB. Some of them argue with me and tell me I'm wrong, lying, my car isn't a 2007, or that the car has am older engine in it. Don't I know that changing the IMSB on an 07 requires splitting the case?!?
If you know your way around and can get access to the Porsche tools and some docs, I'd tell you to go for it.

I have been to Jake's class and built 5 M96/97 engines. Most recent is a 4.0 installed in a 2006 C2S. So nice! I have all the tools to do the rebuild correctly. I also have many of the new parts that should be replaced like the LN IMS Solution.
I'm retired and thinking about selling everything.
Shoot me an email at: stuhpps@hotmail.com.

Actually....I have a MUCH less costly, more reliable and higher performance version that I THINK I'm going with....LS3 swap! Working on the specs now and cost...should be about 1/6 the price of a new Porsche engine and a LOT more horsepower. LOL.....Stay tuned!

Man, so sorry to hear about this. Please think very carefully about an LS swap. If the rest of the car is solid, I think it's worth your time, energy and $$ to do a rebuild.

See when Flat Six Innovations is doing their next Engine Buioding 101 and 102 classes. The 101 is an online introduction and a prerequisite for the hands-on 102 class they conduct in GA where the class builds an engine together.
After that class, with your background, you'd be able to do it yourself. Send your block off to LN Engineering for Nickasil liners as you're working through the classes and it will be ready for you to get.started.

As mentioned on the other LS3 Thread, maybe you save a little money upfront doing the LS swap but you lose $$ on the back end when selling and smaller buyer market.
Most Porsche buyers prefer the original motor so rebuilding 997 motor is best for resale.
