Forced Induction for 2.5L Boxster

[Kenny Boxster]

I don't mean to derail the thread regarding forced induction boxster engines, but if you're interested in more power, search for the guy who put an audi v8 engine in his boxster. There were apparently two engine swaps performed in the usa (one of the guys tried to sell his). The engine is surprisingly cheap $1,000-$2,000, but the integrating it would prove to be very hard I would imagine. Also, another guy on the forums put in a subaru boxer engine his boxster with success, if that interests you as well.

OK, my two cents.
Save the money you're planning on a turbo or whatever and trade in for a more recent Boxster S.

You would spent sooo much time and money on trying to get your old Boxster running with FI that it would spoil all the fun of driving it. These engines are completely designed as NA, trying to convert them to FI is a can of worms.
I know how you feel because I'm driving a Saab Viggen and a base 2002 Boxster. They are completely different beasts, but both have their fun parts and I love driving both of them as long as I keep their differences in mind. So, my option is to have both a FI and a NA car, I drive them depending on my mood and the weather.
Another option is to wait until the new turbo-ed flat-4 Boxster comes out.

There are some add ons you can purchase that will increase the 2.5 performance to the point you will feel the difference but buying HP for a 986 isn't cheap. If you want a bump for the summer try a pulley kit from RSS, if you open up the exhaust at the same time you can get some extra yaya's out. Other than that, my opinion is the best way to buy HP is from the factory in the car you desire. Porsche are really not 0-60 beasts (unless you have sport plus and launch control) or you have purchased a high end 911 the 2.5 Boxster is more about how it handles once it's wound up.

Kenny has a good point here, If you are not a purist to the Porsche motor their are lots of options. The trans will bolt up to most of the Audi and VW family and at that point you just have to get it mounted in there. The audi V8s are great motors but if you want the FI look into putting in the 2.7t which is easily capable of 600hp with some RS4 turbos and a little fiddling. Even the 1.8t is capable of 450hp without major internal work.
