Track day 2.7, 987.1 after terminal engine failure?
Discussion
My daughter just killed the engine on her 06 Boxster. Shame as it had only done 65K.
She didn't heed the low coolant level message when cruising on the motorway and it ground to a halt in the fast lane. Oil pressure light came on for a few seconds before terminal, (so she says!).
I have it back and without inspecting it yet, (AA man said it was toast!) I suspect a full rebuild is required. Thoughts are that I rebuild it, (have done several non Porsche engines in the past) and use it as a replacement for my vRS track day car.
It was a cat D, (although immaculate and had minimal front damage from previous owner) so has limited value. I have a set of Porsche track wheels with Toyo R888's fitted already.
The question are:
What are the thoughts of a home rebuild? It's just an engine, right?
I assume bore work, possibly crank regrind, maybe pistons and all new bearings and seals?
Approximate costs, (ballpark).
Your thoughts appreciated.

Quite right, not in this country!
Had a brief look at it last night. Coolant level not showing, oil level good.
Spins over as normal and when eventually it fired up it sounded like it was running on two or three cylinders so I switched off immediately.
Any thoughts?
Just to add that when it ground to a halt she was in slow moving traffic on the M6 and not doing her usual head down and go as fast as possible, (given restrictions of course).

You're lucky it even turned over at all!
Given the lack of coolant which started all this it's fair to say the oil is going to be utterly shot to bits, and you'll need to do a major flush of the engine.
It's possible that one or more liners will have been damaged as a result of the heat too, and given that it sounded like only two or three cylinders were firing, the sparks will be done as well, possibly one or more coil packs too due to all the excess heat soak once the car stopped.
It's possible you might get lucky, in that you could try a 'major service' of the engine and maybe a bore scope while the plugs are out to check for damage and fire it up again to see how it runs. And / or turn it over by hand when all the plugs are out to see how freely (or not!) it spends and listen for any graunching.
Never knows.

It's worth a try I guess.
Car is parked in the drive waiting for No 1 & 3 sons to be here simultaneously to push it slightly uphill into the garage with the 2 poster. Should be Tomorrow or Friday.
Will have an investigation then.
Thanks for your post, you never know. At least the car stopped in typical slow moving UK motorway traffic and wasn't at full chat!
