Top 5 mods to add HP

Trade in the boxster for a Z06.

Our cars really aren't designed for straight-line performance.

I've been salivating for a TT or a SC kit for my 2.5 for three years now, but when I drive it hard on country twisties I realize I simply do not need more power. Putzing around from light to light in town I always feel underpowered.

So I just stopped putzing around town and I'm feeling much better about my NA 2.5. It actually has tons of power for what it was designed to do.

The guys in the S's behind me on the Tail of the Dragon trip said I was every bit as quick as they were and no easier to keep up with than other boxsters with 3.2's and 3.4's in them.

I say add strut tower braces and lowering springs (and new struts if you the one you buy is over 60k mileage) and you'll be amazed at how well the car will perform around corners, where it was designed to be used.

I can vouch that the 2.5's aren't that much slower than my 3.2 S (2002). Not only at the TOD but in addition NickCats and I spent quite a bit of time autocrossing and his last few events he was only 1.5-3 seconds behind me and I was on R compound tires versus his street tires (a lot of people say R compounds knock off 1-2 seconds from your time). Yes, I'm a bit quicker in terms of power but it isn't as dramatic as I thought it would be. IMHO the biggest difference in a "race" setting is the brakes. I'm going to get quite nervous when he buys race tread.

It also helps that he's become one heck of a driver in a short period of time.

I concur with the opinion of others here. On the street it could do with more power only for fun really as you can't use it seriously. I just took mine for a nice run and found some fantastic twisty roads, and I was unable to use all the power without the car getting aout of shape. So there is plenty there is you drive the car for the purpose it was originally intended.

Mine is my everyday drive car so it see's a lot of miles, but I still love getting in it even if it is just down the the shops to pick up some bread & milk.

My advice:

1. De -snorkle...if only for the sound, but I feels it adds a few horses.
2. Tyres. Well worth the expense for good ones.
3. Work on the handling although they feel more like a go cart than a car.
4. Forced induction
5. 3.4L swap.....from the new Boxy S or Caman would be great

Thanks, Sammy. What can I say, I had a great teacher

I don't know why everyone always assumes that when you try to get more power out of the boxster that you're trying to go fast straight. I grew up a car guy and love to tune out and add performance parts whether it's suspension, brakes and engine. These things come from the factory de-tuned to try and work in all climates, elevations and available fuel quality. If you read my post I'm planning on updating the suspension and update the cooling system (oil included) and get as much as I can out of my car.

On another note, has anyone dropped their suspension 1.5-2" and added 19" rims? I haven't done the math to see if it'll work and would like to add the Brembo 6 piston calipers with 15" rotors while dropping the suspension and adding the 19's (19's are required for the large rotors).

^ I think everyone assumes you want more straight line speed in the Boxster when you mention HP upgrades. Because in the opinion of most people, the Boxster goes plenty fast for what the car is capable of, in turns.

Trade in for a Hemi
Trade in for a Cobra
Trade in for a Vette
Trade in for a 911 TT
Trade in for a Mc Laren

I'm sure this list is debatable but I think you get the idea.

As said by my other well informed people here, the best way to make your car go faster is to get on a track and do some DE's and Auto Crosses with your local PCA. It really does make a big difference and you will really start to be amazed at how faster you are going after your 4th or 5th time out. The best thing about it though is that it is the one mod that you can take with you when you move on to your next car.

That's why you beef up the suspension and braking so you can go faster through corners and power out of them nicely.

Anybody heard of, or know of someone swapping the Porsche boxer engine for the Subaru boxer engine from the STI? One of the guys at my local Porsche dealership was telling me about it and how guys are doing it because the Subaru engine is easier and cheaper to tune out.
