The 50 or 75 shot will be fine, alot of people are having good results w/ the Kpro NOS program. I would use the T3 you have and run low boost around 7psi if you are after realiablity. the base RSX and SI ( i have an SI ) have poor airflow to the radiator once a intercooler is installed. For air to hit 60% of radiator, it must travel through an IC and AC. when driving 60mph the air is only moving like 6mph once its traveled through the IC, then it must penitrate the AC coils before it reaches radiator. Haven't heard too much about the TC A3 over heating, but seeing the radiator isn't working at its potential the engine will suffer some.97K20Coupe said:So in other words i should just boost it with the T.3/T.4 i have in my room? Or will a 50 or 75 shot be safe?
