True. Precautions must be made.

I was just pondering that question. I see quotes here probably averaging around $30K for a new engine installed, all said and done. That's more than a 2007 C4S with 125,000 miles is worth. Quiet a bit more. No doubt you would add value to the car with a new engine but by how much? Everything else on the car still has 125,000 miles.

Subjective topic. If the engine turns out to be irreparable and if it was mine, I would sell the car as a roller for based on other similar stories would bring around $7K, give or take. Add the cost of a new engine and you'll be within a whisper of the cost of a 2007 or even a 2008 C4S with half the miles of yours. Here's one I found with a 2 minute search: https://www.autotrader.com/cars-for-sale/vehicledetails.xhtml?listingId=492807799&zip=34243&referrer=%2Fcars-for-sale%2Fsearchresults.xhtml%3Fzip%3D34243%26startYear%3D2007%26sortBy%3Dr elevance%26incremental%3Dall%26firstRecord%3D0%26endYear%3D2008%26modelC odeList%3D911%26makeCodeList%3DPOR%26searchRadius%3D0%26trimCodeList%3D9 11%257CCarrera%2B4S&startYear=2007&numRecords=25&firstRecord=0&endYear=2 008&modelCodeList=911&makeCodeList=POR&searchRadius=0&makeCode1=POR&mode lCode1=911

I'm with sandwedge. Sell the car and put the money toward a newer model.

Find a used 3.8 motor? Dumping $30k into a car that is worth......30K doesnt compute. But a used $15k motor makes more sense.

But if you just want to have the most cash at the end of the day, sell the roller and put it towards another car.

There are probably 800 threads asking this but does no one ever swap GT3 motors in to C2S cars? I am guessing it is not as easy as dropping a B18c into a civic that had a D series motor before. It just seems like more people would be doing that if it were possible or within any kind of realm of affordable.

a lot of good advice here. However, I would not let a dealer anywhere near this, unless it was warranty work. That is the absolute highest cost solution to your problem. Source the short block from your own sources, plus the other critical components, and find yourself a good indy shop, even if you have to ship the roller there. You'll easily save $10K.

Man, I'm sorry to hear this happened to you. With coolant and oil leaking out together, sounds like the block cracked or you had a D-chunk failure where the cylinder sleeve comes loose, slides up, then a piece breaks off, gets mashed up by the piston and you have coolant and oil mixing together where they shouldn't be. I don't know how mechanically inclined you are, but if fairly mechanical, another option would be to take Jake's and Charles' M96/M97-101 and 102 classes where you actually are taught how to and do rebuild one of these motors. With this knowledge, you could then source the parts and build your own motor to put back into the car. Sometimes there's a class scheduled for around this time of year, but looking on the site it looks like they only scheduled one pair this year and they were in May for the online 101 course and June for the 102 hands-on class. Maybe look into next year's schedule if you have the flexibility to wait it out. I took the classes a couple years ago and it was a great experience and learned a lot about the motors in these cars. These engines are actually much simpler than the old air cooled motors, which is contrary to what you'd think since they have a complete additional subsystem for water cooling.

We don't have any 3.8 engines in stock over on the RND side that are ready to ship. I have one in process that will be done in probably 6-8 weeks, but it would be good to know for your own purposes what exactly failed on your original engine to determine the viability of the core.

Flat 6 Innovations can put together a monster track engine using our Nickies cylinders and all the upgrades we LN and Flat 6 have jointly developed.

Another option like Pete mentioned is to try to do the rebuild yourself. I'd recommend signing up for our hands on classes at the Knowledge Gruppe. Then you can go home with the confidence that you can build the engine yourself, if you are so inclined to go down that option.

You have many options for sure. Just do you homework and if you choose to use a local shop to do the work, make sure they are familiar with the M96 engine and the work required to prevent any future failures.

I am not so sure about the aversion to a dealer...... there are many advantages. First, the work and the engine is guaranteed for two years. This is a very very good thing. A replacement engine is not rocket science ..... it is standard procedure for a dealer as they are removing and reinstalling engines all the time. Regarding the "high cost" of a dealer, well, I don;t think it is out of line at all. When my Boxster engine failed, the costs were similar to Jake Raby.... but with Jake's engine, I got more HP and the other failure modes addressed..... more good things.... but the costs were very similar. For me, at that time, I was going to favor a Raby engine over a Porsche replacement due to the expected higher reliability and HP.

If it were me, as it was, I would weigh a few things: 1) what would it cost to now, simply, buy another car and what do you get for that... that is your value system here. For me, my chassis had 197K miles on it and used prices of 911s were depressed so it made sense for me to dump the roller and move on to a 997.2 2) Dealer replace, 3) Raby replace, 4) Indy rebuild 5) Salvage engine and Indy. The Indy rebuild will save you money.... my indy, a local respected ex-dealer shop foreman, thought he could do a rebuild and save me 10K but he would not be sure until he tore it apart. The guy who purchased my roller put in a salvage engine... I can't remember his total cost but I think it was all about less than 1/2 price a replacement engine. His worked out well and he tracked the car heavily.... and still doing it.

Good luck,
Peace

If I loved the car I'd be looking to upgrade to a better engine if possible, but if not.. sell it as a roller and move on. My GTS.. I'd be getting a factory reman X51 to put back in it as I like the engine in my car quite a bit and have doubts about it being rebuilt to the same greatness.


I absolutely would track a Porsche with 125k miles on it. Not sure my 911 is going to get there, but my Cayman already has 93k and I will track it. Kinda silly to buy something so capable and not utilize its capabilities ever.

Coulda saved money and got a Camry!

jamesinger

^^^ or get a TSX or MT or something in your budget while you save for a 4.0!!

groovzilla

There was just a dead/non-running 2005 base 997 on BAT that sold for $14K last week
That's fairly good money for a non-running car.

sandwedge

Very good money for a 997 with a destroyed engine. Did it say why it wasn't running?

jamesinger

so no one has looked into this?
there is a GT3 motor and trans. for sale in the classifieds right now?
Does it just cost too much to be worth it??
