NOS for 5th Gen

Hey Everbody, im pretty new at mods and stuff so i was wondering if you guys could help me out. I want to put NOS in my 90 Celica GT but i am not sure where to start looking for it. Which company is best? Is it better to do Wet, Dry, or Direct Port? My car only has 85K on it so it should be able to handle it but my other question is how much will it handle before it does damage or blows? What is a good place to get NOS from? any info about nos would be great, thanks!

Thanks for the info. Where i can buy a NOS kit?

buy an import magaize, or just go to summitracing.com or jegs.com...something like that will probably have it. look around
