94 ex
 

Im thinking about putting n2o on my 94 civic. The car has 110000 miles on it.. I was gonna get the compression checked before i did this. I also have an exhast. Could i get away with a 75 hp shot and not hurt anything? Or should i just stay with the 50?

With stock internals I think you should stick with 50 or less

thats what i was thinking,
what should i upgrade so i could do 75 or 100 shot?
