I always agree with this :

The unreliability of the WBX'er is GROSSLY overstated.  Stop perpetuating
the myth...

I've hung up a few 2.1s due to no umph after high miles and just swap
it out with another used one I purchased somewhere, or pulled from a
wreck, etc. These have proven pretty reliable and if ever I have been
plagued, it has been by any number of things, but not the engine
crapping out early in its life.
These things are anywhere between 17 and 28 years old (more or less,
please don't ding me on this) so you can expect all kinds of problems
which are clearly documented here. If you want to use one of these as
a daily driver, stock up on parts and load em beneath the rear seat!
Here's a few more :

Ignition Switch
Rear Heater Valve O'Ring
Accelerator Cable
