Hp upgrades

[The dude]

My last car, years ago, was a 1993 Mazda rx7 twin turbo. There were hp upgrades that generally everyone would follow in certain order. For instance, intake, exhaust, down pipe, intercooler, ecu, boost pressure increase, fuel injectors, mid pipe, boost pressure increase.


What are the normal mod order of events for a 986? I have a 2002 boxster S. This will be a fun street car.

Unlike your Mazda of old, it's both difficult and expensive to squeeze more hp out of the boxster's normally aspirated engine. However, many of us have been successful with some of the following upgrades :

1. A comprehensive and methodical approach to revamping the exhaust system; i.e. headers, cats, cat back ect...
2. Light weight under drive pulley
3. Larger throttle body and plenum
4. ECU re-programming
5. Lighter wheels (a potentially faster and better performing vehicle by means of
reducing unsprung weight and rotational mass)
6. Reducing weight in general; i.e. spare tires, oem seats, lighter battery ect.. (this is
more aimed toward tracking your boxster .
7. Suspension upgrades (though not a direct increase in power, a faster vehicle can be
had by means of better handling and performance .
8. A divorce (reduction in weight by means of one less passenger)

and the list goes on ...........

Cut out burgers and fries. For most, it is easier to loose 10-20 pounds in the waistline, then cutting weight from the Boxster.

New and stickier tires made the biggest difference to mine. Also a good driving school!

though the first decision is figuring out where you want the HP and what you are willing to give up to get it there....besides $$$$$. Is it stoplight power, high end track power, sound, bragging items...

It sounds like what I expected. I didn't think buying a Porsche was going to be a car to upgrade...... just an awesome car to drive.

I will concentrate on just cleaning the car up cosmetically to make it flawless. Then save for the 911!

That sounds like the better plan, you think?

Save up for the 3.6L swap... around $15k, or 3.8L swap around $20k.

Yep. I used to race bicycles and I still ride quite a bit. I get a kick out of guys that are chasing bike weight. After you get to about 19 lbs, its easily $1000 per pound to get any lower. and I look at them and they could easily lose 20-30 lbs off their fat butts for free. Hey just take dump before you ride and you probably lose a pound. There, you just saved a grand.

My road bike weighs 13.1 pounds (you're right on the equation - about a $1000 per pound ). However, as a former CAT 1 racer, even at 45 years old my body fat percentage is still only about 5% .

Cat 1, I'm impressed. I made it to cat 2. Well, actually I placed in enough races to make cat 1, but the USCF changed the rules that year and only national team members were cat 1.

Still ride quite a bit. Cycling here in Miami is great. Organized rides 6 days a week, 50-150 people show up. Several cat 1 and 2s and a couple of ex-pros that really cane the group. Not at 5% body fat, but I'm losing weight staedily.

By the way, you can't race your bike in sanctioned events. Its too light!

I know we are swithing thread topics..... but, I am a triathlete and an ironman. I have to ask out of curiousity..... what was your power output as a cat 1 racer? Also, your my new hero.
