Do a search and read up on this a bit, but the short of it goes like this.

Nitrous will effect engine life even on a perfectly tuned engine.

If you take the precautions, FPSS, WOT/Window switch, NGK TR6 plugs, it will help make it "safer" on the engine.

most people with stock engines run between 75-100 shot on stock I would stay around 85 or lower unless you can monitor everything via autotap or HPTuner software. Or tune on a dyno.

For a basic kit the NOS 5175 is a easy to install dry kit with 85 shot jets.

Nitrous is safe if you dont abuse it.. When I first bought my Firebird in Jan 2000 It was stock except for a cat back.. It had 36,000 miles on it.. When I reached 60,000 miles My oil pump went out and I spun 2 rod bearings.. I bought a 98 motor out of a Junkyard for 800.00 dollars.. It had 8k miles on it.. This was put in jan 2002.. Sept 2002 with about 12,000 miles on the motor I put My nitrous kit on and started out with a 50 wet shot.. I have Headers, full 3inch exaust, CAI, and gears with a walbro 255 fuel pump and some NGK TR6 spark plugs.. I sprayed a 50 shot for a month then upped it to a 75 shot.. I sprayed that for about 2months and upped it to a 90 shot.. I loved the 90 shot and sprayed that for about 6 months.. I put down 292rwhp and 393rwtq with the 90 shot.. MArch this year I upped it to a 100 shot and dynoed again to see if I could get over 300 rwhp.. I was mad at the results because I put down 294rwhp and 412rwtq.. So that same day I put the 100 jets in, I upped it again to a 125 shot.. I dynoed and pulled 313rwhp and 433rwtq.. I was pleased..

It was a little scary to spray the 125 shot on my motor at first but since I put the shot on in march I have gone through 10 bottles and the motor is fine.. I blew a rear end, and my stock clutch is just about to go,but other then that its holding good.. I have been spraying for almost 2 years on this junkyard motor with stock heads, cam, intakes, and bottom end.. I am on my 38th bottle and have 45,000 nitrous miles on my motor now.. My 1st motor lasted 60,000 miles with the only mod I had was a cat back and this motor has 53,000 miles on it and 45,000 has been trough nitrous..

Just dont miss a gear, hit rev limiter, and let the motor cool down after you spray it.. I never spray more then 2 times in a row without letting my car cool down..

yea it is safe as long as you don't get careless with it. 1998silverbird is right on with everything, and also just make sure you take your time installing it correctly, don't take any shortcuts.
