I am not saying that it needs a rebuild, I am just saying that it is high mileage and would need a rebuild in the next, say 60K miles. The thing is I work for Porsche and I am not yet sure if they would give me a discount on a new 993 engine or a rebuild. Just trying to get some info together so I can make a smart purchase after I sell my 87 Carrera cab.

I got a quote for a rebuild and all the new ancillaries like an alternator etc for $15000.00 That included doing some trick things, not a rebuild to factory specs. BTW, it was not for the track car, it was the blue 993 high miler I recently sold.

To R&R the motor is about 50 hours of labor (includes getting it in and out of the car). Sublet of work does run to about $1500. Parts vary based upon the motor condition. The parts prices listed are if EVERYTHING is bad which is pretty much never. Also the parts listed are list prices. Expect to pay around $10-12K unless there are some unusually wrong things in the motor.

I'll have to admit, that $22k figure has had me worried, not that I am in need at the moment, but in the event. I'm glad to see that a few knowledgeable heads agree that it's over the top.

Hi Oshin11,
What ceboyd said. There should be no reason for a bottom end rebuild on a maintained vehicle until at least at 200k. If you drive 10k a year, that's 10 years down the line. Also, 6k for the top end is probably a good number. It's a lot less if you do it yourself and indeed just do the valve guides. A good PPI should be able to determine if the valve guides are on their way out. If they are good now, it's not like they will go bad quickly either.
Good Luck,
George

A documented rebuid by a reputable shop, say Jerry Woods or similar will be a plus. How much of a plus, I don't know. You will never recover the cost of the rebuild. It's like buying a house. A new roof is a plus, but how much more is the house with a new roof instead of a good 5 year old roof? It can be a wash ...

I have a CD full of photos of my SC engine rebuild, all receipts and photos of my friends and me doing the work. And I sold that car for every penny I had put into it. Documentation greatly helps with resale. But since I'm never selling my 993, I just take photos for fun and to post here.

It goes on with the labor charged. $120 an hour is top rate even in expensive places and an SC rebuild should be a week plus R&R of the engine. 45 hours maybe. Then there is also a bunch of cosmetics on the list, like engine tin and hardware plating that's not needed. George
While I cannot defend a $22K rebuild, I WILL tell you that "rebuilding cylinders, rocker arms, valves, etc" doesn't constitute a rebuilt engine thats assumed to be as good, or better than new.
Many parts can be reused but some of the ones you mentioned are not in that category and I state that based on 31+ years of doing 911's. Its not cost-effective to spend all the labor and machine work unless one simply wishes to freshen it up a bit. A properly rebuilt engine should outlast the factory original due to better materials and closer attention to fitment and assembly.
FWIW, a proper 993 engine rebuild (stock) lies in the $ 12-14K range here in our facility, however local labor rates will affect what you see in various locations.

Hi Steve,
Good points. Especially if you actually pay for the labor, brand new parts are the way to go, as the labor is a big chunk of money that you don't want to spend again soon down the line. That said, you really think new rockers are necessary, if the old ones can be rebushed and resurfaced? That's what you are doing to the rods as well. New valves? The rocker shafts, do they really wear? Do you need to resurface the cam housing?
Take care,
George
