vtec wasn't a huge thing back then. the valve covers either came in black or just metal and didn't say vtec on them. the newer engines do say vtec.
as for the tweeter, it was an option, not standard (i don't have them) but i'm sure you could probably find one or just get a better one. and the speakers in the doors are 6.5 i think...
i'd also check (or have checked) the transmission, radiator, water pump, and thermostat because those are all things that went out on me.
good buy btw. :goodjob:
