how much nitrous can it take??

[Dark_5.0]

Since you are running a wet kit, assuming your tune is very good, you can spray a 200 shot without blowing the motor.

Nitrous doesnt destroy motors. Nitrous + a lean condition destroys motors.

Almost every engine I have seen that died from a nitrous overdose had a hole burned in the piston from a lean condition or detonation.

If you have enough fuel and enough timing pulled out you can spray the hell out of a 5.0.
