does anyone know how many engines are allowed on a single ship?

what I really want to do is make it look like there's a bank of lots of little round engines in a rectangular arrangement instead of just one big rectangular engine. It will act like a single engine (1 thrust vector), but will look like lots of little engines. what's the best way to do this?

You only need one Engine Subsystem, you can assign multiple glowpoints to it. I would suspect theres probably a limit of something like 256 of those per engine, but that's sheer guesswork. Unless a coder says otherwise, you should be ok with what you have in mind.
