from my knowledge of nitrous, NOS was first made for big engine but still have kits for imports. Dont get me wrong NOS is good only if you are going to run very high shots 75+. And if you decide to go NOS go with direct port! On the other hand if your going to run 75 shots or lower, i like the ZEX kit. There made to run perfect for 50 or 75 shots (with a few mods if running 75's).ZEX is also not that expensive and is well worth the money. Later this summer i'll be running 50 shots of ZEX with stock internals, its not really needed till you go higher in shots. Ohh yeah go for the wet kit!

I hope i was of some help?

peace
