Whats the next step?

Hi. I need some ideas on what my next mod should be. I have a short ram intake with custom ram air fedding it, and a catback exhaust with gutted cat. I have no clue what i should do next. Any ideas?

Also.. will my stock motor with 135k miles on it handle a 75 shot of nitrous? i had a timing belt replacement about 20k miles ago.
It runs really smooth doest smoke or sputter. I just replaced the plugs and wires with all platinum stuff and i run synthetic.

yea it should but it wont be good for the engine. the next mod should be headers i guess, or if u got a lot of money go ahead and turbo it.

^agreed

hey if i made some TUBULAR headers for a 4afe would anyone be interested in buying them, im making one for a geo and its turning out nice figured id share the wealth
