which year has best engine

ok im wondering which year of CIVIC has the best performance or performance potential?

the civics i'm talkin bout are ones i'm able to get my hands on cheap. not like type-r s or right hand drivers.

and if there isnt a real good answer, what engine type is good with a few mods, like heads or forged pistons, something like that.

i heard 95's are good i have no reason y they say it is

if u can help me out that would be awesome
thanks
