I've done the research on here and the I/H/E method seems the way to go to begin making the box faster. I went on eBay (yes, eBay) since I got a short ram off there to look for headers and exhausts.

Short rams were pretty simple, but I'm still not really sure about H/E's. I found some stuff on eBay, how does it look?

Headers:

I/E/H wont give you much on the 1st gen XB cause they have a smaller engine ill help it breathe better but nothing big

 

lets see....i started with maybe 80 wheel horsepower....with AEM short ram, Borla cat-back, and DC headers....i'm maybe at 90 horsepower


the ratio for 1NZ-FE engines is about $100 per horsepower

 

idk what that means

 

$200 for an intake..........2-3 horsepower

$300 for headers............3-4 horsepower

$300 for exhaust............3-4 horsepower

$3000 for supercharger.............30-40 horsepower


turbo? forget about unless you wana blow your engine in 10k miles.

nitrous? 15 shot max on a stock engine.

 

i see... whats the single hamster set up?

 

so this means you wont get much at all with basic bolts on,but as your title says if you want a little bit more power then go for it,xb are show cars not really performance cars espcially the 1st gen

 

You're not going to be going much faster than you are now, even with an I/H/E combo. Pretty much get what looks and sounds good.
