Re:how much horsepower?
 

You are right it would not be N/A ;D. I'm not a fan of it but you know that laughing gas is the quickest and could be cheapest way to get and extra 30 or 40 hp and is simple enough to install by almost anyone. If you know how to do it, then yes go ahead and install the pistons, but if he's going to be Turbo in 2 weeks, he should not do that period, he should wait and spend money on the turbo. He'll be happier that way.

NOS better know as NAWZZZ is the most expensive upgrade you can do....I see it like this...$400-$500 a kit and then $40 to fill the bottle a week if you rarely spray it.
In one year that is $2080 for filling the bottle only ... that's a bad ass turbokit with some nice standalone.

i'm curious where the other header gets installed...

(people saying headers when refering to a 4cyl == funny!)

Re:how much horsepower?

Re:how much horsepower?
 

i have, but they're still on the same flange usually (therefore still a header)
