Engine Replacement Comparative Costs

[986FortyEight]

The whole panicking around engine failures is driving me nuts!
I just love my car and will deal with failure when it happens.
Reading other boards I see plenty of boxster owners replacing blown engines for low mileage 2nd hand ones for 3K. Also, in many cases the failure might not be catastrophic and allow for a rebuild.
I think that if upgrading the weak parts with the Raby solutions may be a good idea if fear is preventing you from truly enjoying your boxster.
Also, if you were to buy an upgraded engine to drop into your tub, at 12k that would still be a nice price for the fun of driving such a fun car. What else would you buy for 12 large? a Kia? Give me a break! many of us got into a porsche for cheap knowing it would have a cost at some point!
