This is one of the areas where I completely disagree with the masses of "conventional wisdom". The stock clutch uses a dual mass flywheel, replacing the clutch does not necessitate replacing of the flywheel, in most cases just scuffing the surface with a sanding block and cleaning with brake clean is sufficient. if it's scratched pretty bad the surface can be ground by a competent machine shop it just takes a bit more effort to secure the flywheel properly. Yes, if you managed to wear the clutch to the rivets and gouged the flywheel it will need replacing but that's pretty rare. Stock replacement flywheels as with most OE parts are spendy, aftermarket simpler lightweight flywheels are substantially cheaper and offer less rotating mass making the engine feel a touch peppier. For me as an autocrosser it's a big no no as it's not legal in stock (street) or street touring classes. If you aren't involved in motorsports this isnt a consideration. Yes it's easier to replace it all once than to risk pulling it apart again but honestly the z33 isn't a particularly difficult trans to pull and with a lift I'm sure I could have one out in about half an hour, probably about an hour sans lift. Back in is trickier especially when on your back.
With cost being your main factor I'd scuff and clean the flywheel, get an aftermarket disk and PP recruit a bud or 2 and plan on spending half a day on it, mostly learning where what is and fighting the track back in, also be sure you get a clutch alignment tool, most come with but without you'll never get it centered right.
