For the reasons above, more damage can come from storage than continual usage. Not mentioned is that gaskets and rubber seals dry out, become brittle, hard and cracked and upon useage will fail in short order needing replacement that can be very labor intensive and costly.

Not trying to discourage you by any means, just stating what I have found. Your best bet may be to sell the motor in your car to a buyer than can test drive it and hear it run before you pull it. Then, if you have the confidence, install the "new" motor in your car.

No of course not I want a balanced argument here pros and cons.

Porsche checked it for moisture and your right I have no idea how?



What I do know is it was stored in dry heated storage with the all the intakes sealed and then resealed every 6 months.


I think the demand for an engine at the moment may not be there, however I wonder if 996 turbo price are keep rising , I wonder what it would be worth in 10 years time?

An investment perhaps, perhaps not.


What are low mileage 993 turbo engines going for these days, anyone know?

Any one care to hazard a guess as to the value of this in todays market?

This is a full engine including turbo chargers and exhaust.

Its quite a rare discovery which makes it difficult to price. What I do know is a new remanufactured unit from Porsche is $69,920.

I'm also very tempted just to whack it in my car

Thanks again guys

Hard to put a price on the engine.

While it is a delivery miles engine it comes with *no* warranty. Thus the buyer is at risk the engine could suffer some fatal failure out of the crate so to speak.

While not that common of course it is still a risk.

A new factory engine is expensive to be sure, but it does come with some warranty. Not sure if this is worth the price difference but it counts for something I think.

As an aside, my Boxster needed a new top. I priced a new factory top and the cost was $3300. I asked for some goodwill -- the car has nearly 300K miles on it. But as I waited for the reply from Porsche I got to thinking at $3300 factory tops weren't flying off the shelves and chances are the top would be nearly as old as the car. My concern was that the new (but old) and very expensive top would not have nearly the same service life as the original top. So I told the SM to cancel my goodwill request for I didn't want to use the new top even with a discount and instead had an aftermarket top fitted. At some point new old parts become more more old than new and not as worth as much money as they were when they were new new parts...

Anyhow, the engine probably needs new head gaskets.

(A person I know offered me a nearly new Turbo engine (I don't trust my memory to say what price he mentioned -- but I could have easily afforded it and considered it but the engine in my Turbo is just fine -- but the price wasn't very high) but he did say the engine would need going through before installling it in the car to address among other things the head gaskets. The going over would cost nearly as much as the engine he said.)

Also, while the person and I didn't talk about this I would worry about the water pump seals, the RMS and FMS and turbo seals along with fuel injector seals/o-rings, etc. There is the enigne coolant hose fittings that probably should be attended to before the engine is installed in the car.

Since the engine is new I'd take a close look the layshaft gear to make sure the bolts were not going to loosen up or the key come loose. To get to these items the cases have to be split. Not cheap.

Hopefully a tear down finds no rust spots anywhere on the valve springs (stress fracture can arise from a rust spot) and no rust spots on the rods, or crank, cam chains, and the cam lobes and valve lifter faces are without any signs of corrosion. That cam lobe/lifter face interface is a critical bearing interface that relies upon proper surface finish, ideal metalurgy and sufficient lubrication to deiver a long and trouble free service life. In fact I'd be tempted to replace the lifters at least. Hopefully no lobe goes flat as the engine is used.

Sure someone could buy the engine and just shove it in a car and see what happens. But not if he paid anything more than he would for an engine from say a salvage car.

I bought a complete brand new turbo motor a few years back for $24,000 with no core. It came with a factory warranty for 12 months and 12,000 miles. That was from a local Porsche dealer here in Virginia. Full retail at the time was north of $40,000. But only fools pay retail. For the kind of money they are asking you can get a very stout motor built to your specifications. Just my 2 cents.

yeah, 25k for brand spankin new motor is right and fair, if coming from an unknown but factory related source, builders and their costs to rebuild to include into estimates from a hi to low perspective aren't fair as they aren't near equal for the purpose of trying to determine a crated new motors "worth". an indies rebuild cost is going to be cost of labor and parts and thats it!
