Ok I just rebuilt my enigne to stock spec basically. .030" milled head, .040" over pistons, clevite bearings, MLS headgasket, PT rockers/lifters, crane springs, UDP, CAI, 4-1 header, 2.5" testpipe and exhaust, 55mm TB, 255lph Walbro, MSD Coil, ported intake manifold, ground wires....i think thats about it. It has about 3k on it and running pretty strong.

I want to use some Nitrous to make it a little quicker for the time being because I am starting a 2.4 turbo build up for later on. So I decided to pick up a NX wet kit with 50&75 jets.

My questions are about safety as far as what I need. Anything in particular. Just a WB02 or EGT??

I have read a lot, but I am a little nervous about the first spray?? How do I know when I am ready or its safe?? Also I see a lot about what is safe for our engines....50 or 75 is our limit??

This wont be used very often, but it is currently driven quite often.

Thanks for any insight!!! :)

Well I think I answered all my own questions...just needed a few more hours of reading.
