Ok, so my question is really simple : Are bolt-ons needed for safe nitrous use ? I own a 2.2 coupe stick and I already got the gmpp perf. cat-back and wish to go on with headers, intake, interceptor, wideband a/f but i wanna go nitrous before all those mods. Is this a good idea or am I gonna send 50 extra horses into somethin too restrictive ???? And are any bolt-ons more importants than others ????

No, bolt ons arent needed

well this is what i did on my 03 cavalier for my nitrous.

1. only changed muffler
2. intake filter on s-tube
3. zex 55 shot nitrous kit
4. be smart and not drive like ass

BTW get a wet shot instead of a dry shot, it's worth the extra $$$

yea mine was a dry kit ran 2 bottles threw it.

wound up messing up my #2 cyl but it was a commen problem with the timeing on the 2.2 03 cavalier ecotecs and sunfires

you don't need them but they'll certainly help your gains
