A wet system will inject nitrous and fuel at the same time so tuning isnt required.
however if you run a 75hp shot you will have to retard the ignition timing by 4 degrees if your running it on a stock motor and i wounldnt recommend a 100hp shot for a D16 will no tuning and inadiquate fuel supply you will risk blowing your motor mabe not straight away but eventually.
run with a 55hp shot it will be safe and you can run it all day and not have an issue with it as your only basically pumping more air in so its not that much different to running a mild turbo setup. really dollar for dollar its your best bang for buck upgrade!
Thanks for the info man helped me alot I'll pm
you tomorro just want bit more detailed info on the zex
Thanks again
You won't need to retard the timing at all with 75hp. On old big block Chevs you might but not on a multivalve EFI engine. I'd get a wet system and have it tuned on a dyno by someone who knows what they are doing with nitrous.Quote:

If you want to get consistent results it is necessary to get a bottle warmer and a pressure gauge. With these you can keep the bottle pressure around 900-1000psi. If bottle is not warm enough the pressure drops below 900psi and as it drops you lose performance.
It will be necessary to get aftermarket headers and a good exhaust system. Without these you will reduce the nitrous gain because the engine will choke itself because it won't be able to expel all the exhaust quick enough. Make sure you do not use it at low revs with big loads or you will find out what nitrous backfires do to inlet manifolds and bonnets (it is not pretty).
One more thing, nitrous is NOT All Motor. This thread should be in the Forced Induction section. ;)
Nitrous Oxide in both gas and liquid form (when pressurised or released in the atmosphere) is NOT I repeat NOT flammable. It is an OXIDIZING AGENT that enriches the OXYGEN concentration in the combustion chamber.Quote:

It's laughing gas.........
all pressurized gas cylinders have a safty release valve and will expell there contents if something goes wrong (theory) :P so it is recommended that you run a emergency release tube from the bottle under your car so that if it dose release the gas it goes out under the car and not into the cabin.
it is stated on the ZEX installation guide that for untuned motors running a 75hp shot they recommend retarding that ignition timing by 4 degrees so you dont have to, and i would put this down to the motor being untuned running factory computer after market tuned no worries :P
may i also suggest to upgrade the oil pump to a d16z6 (usdm) type, D16Ys oil pump isnt really the best for what its supposed to do. I/H/E will deff compliment the zex/nos system, & as stated before, a 75hp shot would be pushing it, to be on the safe side id go a 50 shot. bigger tb, skunk2 im would also let in a bit more air, & since your going to the trouble of fitting nitrous & getting tuned, may aswell go with them or get tb bored & port match im.
Keep your stock injectors, since your not hitting nitrous all the time, bigger injectors are really not required. only in application where boost is always present, then id start thinking about bigger injectors. if your really keen on bigger injectors though, prelude H22A injectors. im not exactly sure what size they are but i know they flow alot more compared to Y8s stock 240cc injectors...
^^ as above but if you use a wet type system you wont need to upgrade your injectors as the system adds the required amount fuel to nitrous for you.
honda push their injectors pretty hard,dont know bout d series but bseries see 90%+ duty cycle at high rpms.Id at least look at bumping the fuel pressure + tune,if stock injectors.
As lookingforboost posted there is no need for upgraded injectors when using a wet system.
If you only have a standard ECU I would not be using a dry system (I would never use a dry system anyway, but especially not with a stock ECU).
BTW, how many of those offering advice have actually used nitrous on a car of their own?
