hey ppl i need some help, cause i'm real confused. i have a 94 civic cx.....it's in canada. my engine is a D15B7 and it's a cx....is the us cx different from a canadian cx? i'm not sure if i have the original engine or not, but my block has all kinds of writing on it as if it were from a junk yard or something. also i've read about silver to D15's.......could someone plz explain cause i have a silver valve cover. some parts look brand new and the engine it's self looks old. i'll give u some little info i noticed: the cam gear cover thing is the only thing that says the engine code which is D15B7, but it looks brand new and the sticker has no fading or tears so i bet it was replaced. also the fuel rail says ITP.....is that original on all eg's? the tranny says C5f P20. also my exhaust piping and header is 2 inches is that normal size on a stock civic?
so is it all original???

plz help me out i'm so dam lost

thanks
