I have considering going the nitrous route to really make my prizm move. I want to go with a wet kit because nitrous is a little unsafe due to leaning out the fuel so bad.

Has anyone had problems running nitrous on any of their cars? I only want to run a 50 shot, nothing crazy.

Even if you don't blow you engine you surely will create much quicker wear and tear on the car, thus premature failure of parts.

I only plan on using it every now and then, not daily or anything.

and yes i know how to retard the timing accordingly so it doesn't knock.

the bottom end feels real strong and i plan on using moderate jets. prob a 35 on the street and 50 at the track, not a 100 or something unreal.

If its being fueled properly (ie not running lean) this particular motor should last a long time with Nitrous even if you were to use it every day. The key is proper setup w/enough fuel and not too much timing. If its not detonating (pinging) and running hot from being lean is what kills the engine. Nitrous is a form of forced induction. The engine has forged pistons & rods, it should last a long time even at 250hp with out even breaking a sweat. You spent the money on good components, might as well get some use out of them.

^it also has 11:1 compression ratio....

hah, 250hp going Forced induction can be tricky. And you wont do that with 11:1 CR either. It wont be easy with nitrous either. Just because you have forged rods and pistons, doesnt mean your engine will be super strong.

I am more form the SBC Chevy world, but I see tons of guys running 11.0:1 compression and N2O. With Forged pistons and a stronger lower end, its just begging for nitrous. I had planned to do a 383 stroker with N2O, but then I got into Turbo's and SC's. I personally wouldn't be jumping up and down factory piston with that high of compression, but I see guy running 5-6 SC as well on similair compression and the factory cast crap. The key is to do your homework with Nitrous, don't cut corners, and just because you neighbor down the street did a kit cheaply and used it 10 years doesn't mean its safest choice. I would do a wet kit, bottle heater, RPM window switch and use a quality name brand kit and use reasonable sized jets.

The car already runs rich as hell from the stock tune, but i would think it would be safer if I did the following to accompany the nitrous:

Fuel Pump
time for some injectors maybe?
fuel pressure regulator
wet kit from NX
colder range plugs
timing retarded accordingly.
