nitrous question

well guys i am working on a b20 turob but in the mean time i wanna spray on my d16a6 that is stock internals....bought a nx hitman wet kit....what would eb a safe shot to spray on???...

50 shot would be safe, 75 shot would be pushing it without good tuning.

so what would you tune in on it to get it to work perfect when i spray...i need pull back timin,colder spark plugs?

Good tuning is going to require a dyno and wideband O2 sensor. You need to make sure you get the Nitrous to fuel ratio just right, also you will need a bottle heater to keep consistant bottle pressure, that is critical. If you tune the car when the bottle pressure is say 950psi and then it drops the 800 psi then you will be running rich. Every time you spray the bottle temp will go down a little at a time, also if it is cold outside then the bottle pressure is going to go down as well.

i have a bottle heater...so i just take it to a dyno palce thats tunes and tell them dial my car in?

Yep ;)
Make sure you top off the bottle before you go so that it is full.
