how much no2 can a stock ls1 take, using a wet kit that is

 

I dunno but i sprayed a 100 dry shot before my mass air and another 75 dry shot on a push button, also before my mass air on my 98 chevy standard cab pick up 4.3L V-6. and she loved it. go big! my brother sprayed a 200 shot wet kit on his stock mustang 5.0. Still running today!!!!!!! go big!!!!

 

150 is good enough unless you want to get into nitrous specific stuff like a purpose nitrous cam, a nitrous tune, stand alone fuel system and so on.
