.....before I get tuned? I wanna stay NA and trying to think of other mods that aren't too expensive. (Besides gears and ITB's) Any ideas?

 

how much is too expensive? u can always add a test pipe(very inexpensive) or upgrade cams(a little more pricey)

 

any mods under $500 I guess. How much are cams and where can I buy them?

 

Judging by your list you could go:

Krank Vents, Testpipe, Voltage stabilizer, AP1 Version 2 ECU.

Production Cams haven't really been proven to be an effective power adder, and custom grinds end up over 500 by far, every time.

however the 500 you spend for a good tune will outperform any of these mods. My suggestion to anyone is not to shortcut the tune, or the parts. Even tuning for your bolt-ons will be worth more.

 

u mean tuning with VAFC right? Or is tuning different from VAFC's? Also, what do krank vents do?

and yes, the VAFC tune, the s2000, especially the 00 s2k, runs rich from the factory. You can tune out some of the air safely, therefore increasing hp throughout the powerband.

 

ok, thanks. Lastly, when I get my VAFC tuned, Im assuming the tuner will dyno tune my car right?

 

yeah, the butt dyno is not something I'd trust with my Air/fuel ratio.

 

why is that?

 

Because the butt dyno lies. You feel torque more than hp...if the torque curve moves you will feel it...you may not feel the hp change especially up top.

Consider an AEM EMS if you want the most out of an NA tune.
