I want to build a D16 non v-tec w/ a agressively milled head, high compression head gasket and a 50 shot of nitrous. Now what I need to know is how long do you guys think this would last me?

 

High compression and nitrous don't mix.

 

So how long do you think this will last me? The reason i'm asking is because some guy owes me some money and he has a 1990 civic 4 door sitting outside of his house that i'm about to repo from his *** for the money he owes me, and yes the car will be my beater car that way I could park my rex.
