Do I need engine management?

I traded my Honda for a 94 m edition, with what might be a blown turbo. All I know is that it was run previously at 5 psi with no intercooler. There is smoke pouring from the intake filter, the wastegate is not connected to the turbo currently. Actually the wastegate is busted. There are no upgrades on the car, stock internals and injectors. It came with more piping and a new eBay front mount. If I just bolt on another turbo and running at low boost, no more than 5psi would it be ok to daily drive? Do I have to have engine management at this level? I only have a few hundred bucks to fix it. If nothing else I can put the stock manifold on and run it NA. Since the the oil lines are already run and everything hooked up, I figured it's probably easier just to fix the turbo, but I'm really short on cash. Besides that, I need new spark plug wires, driver side top latch, there are holes in my trunk from a giant wing, and my tan interior was sprayed black by a previous owner. Also missing the m edition wheels.

You need injectors. You need engine management. Of course, those two things are expecting that you want to drive the car at WOT and make actual power. You can drive the car, albeit out of boost, with no engine management and stock injectors.
Frankly, I'd just swap the N/A manifold on and spend my time fixing everything else before replacing the turbo and buying megasquirt/injectors.

Since it's the 1.8 my injectors are good for almost 9psi? I really don't want much hp right now. This is my first turbo car. I would rather not have to run it NA, at bare minimum what do I need to do to run it at 5psi? You are probably right I should pull the turbo off and source better parts, maybe try to save money and trade some stuff I already have for more parts. This car is going to be my daily driver for a while.

9 psi is if and only if you you have a fuel pressure riser, something like vortech's unit or BEGI's adjustable unit. As the air goes up with RPM (because of boost), your fuel needs to go up as well. These two things, or an aftermarket ECU with MAP sensor, do that.
If it's a daily driver, and you have very little money, TAKE THE TURBO OFF!
Other things will break, you already mentioned non-turbo items that need attention, and you have, as far as I can tell, a very half assed turbo setup that WILL grenade your engine soon.
Do you have any pictures of the engine bay you can post to help us identify any other problems you may have?

Yeah that's what I figured, from what I was told the turbo was bad from the start, it's been run for a few months like that, it's not hooked up now and runs well. I traded a 96 civic coupe with a few bolt ons. It has half the miles my civic had and with it being an m edition I figured it was worth the trade. On Friday I'll convert to NA and replace the valve cover gasket, its leaking a little. Any ideas on plugging up the oil line?, it's tapped on the pan, I guess I can just put a bolt in there.

Should be an NPT thread in the pan, go to home depot, they'll have a section for brass plumbing hardware, where you'll be able to find the correct NPT plug for it.
Just to clarify: NPT stands for National Pipe Thread, and it's a tapered thread, so a standard bolt won't seal it correctly, only another NPT plug.
For the feed, the hole in the block the oil is coming from is plugged with a bolt and brass washer, much like a small oil drain bolt. I'm sure someone here will send you one for the price of postage, if you can't figure out a similar fix.

When I got home the miata caught on fire, when I pulled up I saw paint started to peel up from my hood. I was like wtf, popped the hood, and flames where shooting up by the turbo. I put it out with a hose, turns out I think the oil line busted on top of the turbo or exaust manifold and started it. Now my hood is screwed, but everything looks ok under the hood.
