my supercharger will compensates that...

The car has a pretty good st-steel header on it stock. The power is in the exhaust. High flow cats + 2" > 2-1/4" pipes. Larger is badder**. Go local to a good race shop. I'm lucky, I have 3 speed ways and 1 dragstrip near by so there are a lot of backwoods roundy-round race shops that do stuff for cheaper than China Import Commie Garbage.

I wish I had dyno'd with each part individually. I got 17 whp increase with intake, header, axle-back exhaust and crank pulley.

SO, if the header was a zero, those other mods sure paid off.

Hey, it adds up exponentially! (whoa, that doesnt make math sense - but it may be a good geek math joke). In other words, It's MORE than the sum of the individual parts. The mods feeds off each other like vampire whores.

- NO! not: MODerators!

i bet it does more cumulatively than by itself....was talking w/ peter about that yesterday in the chatbox...

I have UD pulley, CAI, and Thunder axle-back exhaust w/ stock exhaust manifold, and am making basically the same 17 whp gain that Garm got off the same mods with a header. It doesn't seem like the header does very much for our engine. If you go with a full custom exhaust, I'd guess you'll see a few more ponies, but I think we're gettign pretty close to the max HP on this engine (NA) without getting into engine internals/ higher compression mods. You're right to think about getting lighter rather than getting more HP.

As other have said, you want to have a good vision for your mods before you start investing. If you only plan to have some fun with the car and keep the budget low, then my route w/ some light wheels/tires and a few suspension mods will probably make you happy. If you really want a serious street/strip machine, then save your $$ and buy a FI setup that will really perform at a much higher level, then beef-up the rest of the car to handle it.

Yeah I have found that the most important things to me at least are lightening up the car, and suspension. I would like a faster throttle response and a little bit more power but not a crazy amount, and thats it... Very doable in NA I think... As far as FI, I just can't see myself doing it until I get another vehicle and make this one a toy... soon probably...
