The 2.5 is the BEST engine Porsche has ever produced! It is the very BEST in everything that matters! Anything else is just not as AWESOME! Why even discuss any other motor that Porsche has ever produced??? All the best drivers know that if you don't have a 2.5.....you ain't got nothing. Also the best year Porsche Boxsters were ever produced, hands down, 1998. Porsche should have just stopped there when they achieved perfection.
Of course, I could be a little biased because that is the motor in my 1998 Boxster.
