I bought a 99 boxster from a friend that came with a new 2.7 engine. He bought the engine at a car show thinking it will fit his 99 boxster one day. It has the paper work from Porsche. After reading the posts here, a 2.5 to 2.7 swap is really not practical. Contact me at
oldcar@hotmail.com if anyone is interested buying the engine or selling a boxster with a bad engine.
