What is the biggest shot of nitrous you can put on a stock es motor without causing any damage over an extended period of time? suggestions?

 

If you are running stock internals i would not run more than a 75 shot

 

On an ES, my advice would be to leave NOS alone.

 

I wouldn't put nitrous on anything other than a drag car... just my personal preference. What other mods are you planning to accompany the nitrous?

 

No reason to get NOS if nothing internal has been done, spend the money on other things such as CAI, exhaust, and headers first, that don't have a chance of ruining your engine, plus if its a daily driving car it can give you better gas milage.

 

It would aggrivate me to have a car with 120 HP one minute and then 175 HP for 10 seconds or however long the shot lasts...and that's aside from the internals.
