Hey guys I have searched and can’t really find what I need. So sorry to post another “Nitrous Question” thread.
Ok I have a 93 ls with SR intake and exhaust. the real question is wet or dry? What preperations should I do to my engine before wet? I know dry kits you basicly(sp) need more fuel. FPR and higher volume intank pump. But I don’t really know anything about wet kits. Better perfoming? Safer? Preperations?
thanx guys,

id never run a dry setup, its just not safe. depending on the size of your shot, make sure youre running 93, retard the timing a degree or two, and run plugs that are a step colder. you wont need an FPR, or a pump or anything. the stock fuel system is fine for a 50-75 shot. make sure you use a WOT switch, and get an rpm activated switch so that it only engages at WOT and above a certain rpm.
wet kits are a dry kit that have an extra line that also supplies more fuel when nitrous is injected (1 nozzel for nitrous and 1 for fuel), dry kits only have a nozzel for nitrous and use ur existing injectors to add the extra fuel that is needed. What i dont like about nitrous setups is if u wanna be safe u need to retard timing and run the colder plugs which is good BUT the retarted timing and plugs are gonna sacrifice power when ur not on the juice, so u need to ask urself how much ur really gonna be using it, me i wanted nitrous but i wouldnt use it all to much but on the occasional “sprint” so most of the time my performance would be deminished
buy a msd digital 6 and when the nitrous is activated it retards the timing for you. then when your not sprayin your not sacrificing anything.
dry kits IMO are safer than wet kits, when installed properly. for small shots they cannot be beat. for larger shots you would need larger injectors and an EMS that supports nitrous. when you activate you nitrous the computer will retard timing and add gas. allowing it to be tuned for spray.
with a wet kit you will NEED an msd window switch to shut the nitrous off before rev limit. rev limit, on most fuel injected cars, is fuel cut. while running NA or a dry kit this is fine because NO fuel is going into the cylinders. NO gas + nitrous = no combustion. with the wet kit it will still be sprayin gas into the cylinders when rev limit is reached. a little gas + nitrous = lean detonation. this will lead to the end of your engine.
will using a 75 shot dry setup without changing anything still work fine?
