Excessive maintenance?

sorry, should have mentioned it’s a 5th gen Prelude

the stuff that will be done: t-belt, balance belt, water pump
the stuff I’m 90% sure will choose to do: auto tensioner (supposedly it fails with regularity on the 5th gens)

so it’s all the other stuff I’ve listed I’m thinking about

$200 is not that bad, it’s just that in a month or so, I’ll be under a severe budget…so I want to separate what should be done, and what can wait another 80k miles (my car has approx 80k now)
