93 eclipse gs - a few questions

hi, ive been looking for about a month for a decent ride (mainly a beater) and i found a 93 eclipse gs for 700. i just have a few questions:

- do any of the first gens have popup headlamps?

- what is the engine in a 93 gs and what is its estimated hp?

- should i get the gs? (i mean the price is right, just gotta check other stuff out).

- is it hard to swap in a gsx engine into a gs (is it even possible)?

thanks in advance
