Boxster S dead, what to do

[Cunningr]

I know your worried about the money ect... but you are talking about spending the money to put in an LS1 engine, that is pretty expensive.

Flat Six Innovations offers several stages of engines for the Boxsters and 911s.
Big Bore and increasing levels to full race engine. Probably expensive, but if your willing to drop $10K to 15K on a LS1 conversion, you might be able to go with a Big Bore Kit and keep the car true to its heritage for similar money/or not. Anyway might be something to investigate.
