ok guys i got a 86 rx7 na 5spd with these mods. cold air extension,rb header, 2.5 in exhaust single muffler,no ps,no ac, no egr,running premix, advanced timing. i run usually 14.6 . i will be running nitrous for a special import drag event. i need to know what is safer and better to run. whats the best kit on the market for my setup? wet or dry is better. and whats the highest shot i can go with without altering my fuel and all. thanks

 

Wet is the ONLY way to go. I think 65 is the highest you want to push. Go to www.fc3s.org they have a whole How-To with pics and info that explain using n20 on a N/A.

 

Stay with the wet applications. A couple of my friends went with the dry zex kit, and man that bottle torn that poor wankel up. I've heard of people pushing a 75 shot, but requires some work, and on top of that say goodbye to your longevity.
