is it worth putting header on a twice-cam ka? would there be any significant power gains?

also how well would it stand a 50 shot of nitrous

 

50 is nothing, just do 75-100, that'll do.

 

I heard the hot shot headers add 12 HP th the wheels but dont qoute me ive only "heard".and i believe a 75 shot is all you can safely run on the stock 240 fuel system.

 

A HS header would be a good improvement of hp. As for nitrous, i always hate seeing people spray without better internals. thats just me though i guess. Id just rather have hp all the time rather than just for a shot at a time.
