I heard that NOS can not be put into an RX-7. Is this true and if it is how would I do it? Also what company makes systems for a 7?

 

Don't do it unless you KNOW what you're doing (and since you asked, i'm gonna recommend not). It's an easy way to blow your engine. Some people with huge turbos use NOS to reduce spool time, and I have heard of a few people running a small shot successfully, but i have also heard of several blown engines from it.

what about that venom computerized nitrous system that seems to be pretty safe. also what if the nitrous was used in conjuction w/the j&s safeguard? would that be safe ?
