Need advice on making boxster quicker.

...so you're telling me that your U.S-spec 2.5 Boxster had 135-155 bhp to begin with?

The new codes were re programmed into the cars computer for $395 and the car is no longer detuned with American emission standards. I now have a 1999 2.5 Boxster that whips my neighbors 2002 3.2S. Gas mileage has increased from 18-24mpg in the city and up to over 30mpg on what little freeways we have here. Horsepower has increased 50-70hps. It runs rich and wants to jump to a higher gear at 4000rpm. It took about 20 starts to set all the codes, however I noticed a huge performance change immediately. I was skeptical, however found 20 Cayman and 911 owners in Hawaii that had this procedure done. All you have to do is befriend your Porsche mechanic each year upon emission check, pay a small fee of $150 and you will love the results.

Somewhere, Al Gore is weeping!

Welcome to the club

Did anyone tell him he bought the wrong car yet?

Seriously, the 986 platform just don't have the support for engine mods except the 3.6/3.8L swap which is perfect if it's done right.

987 guys have TPC Racing turbo kit, Sharkwerks RS350 kit that have been proven over and over again that they work.

You have a point there, I have a black car, and now it looks filthy! I have to keep telling myself that I bought it to drive, not show, but it still bothers me.

Also since its a used car im sure you will need to do a minor tune up and why not change the OEM filter for an upgraded one. 80 bucks on ebay.

Well, it killed my MAF (see my signature)
But in all fairness this happened after I re-oiled it strictly following the procedures by BMC (I was actually using LESS oil than they recommended in their instructions)

Nobody mentioned an underdrive pulley, those free up power across the board.

I've run with an oiled filter on my Evo Hi-Flow intake for going on five years...never had an issue. Usually it's the user "over-oiling" that causes the problem, not the design itself. A little oil goes a long way...

If after a year of DEs you still need more HP just drop in a 3.6L.

Well spoken and good advice.

It's been said for decades: there's no replacement for displacement. My 3.6 has given a couple of Carrera S 997s more than they liked.
