New owner, age old question :-)

Hi guys,

I'm brand new to the board, and I just purchased a 2000 Boxster S. I've had plenty of sportscars in my life, and well, I like to tinker with them and make them faster.

After reviewing some of the aftermarket parts available for the car, it looks like there really isn't much out there besides an engine swap, turbo or supercharging, that nets some real horsepower.

So I did some research, and my car has 250hp from it's 3.2l engine.... Question is, how is the 2005 putting out 280 with the same size engine? What are the differences between the 2000 and 2005 engine? Another 30 horsepower would be a sizable gain and it obviously doesn't involve forced induction or a larger engine.

Can anyone help?

Thanks!

Todd
