The short answer would be to start with a turbo 13BT engine and go from there.
The 13BT is already designed for boost, and it's a better platform for turbo power to start out with rather than band-aiding your non-turbo 13B to try and make it work.
By the time you fix all the crap that needs to be thrown away and replaced on your non-turbo 13B, you could've started out with a good, imported J-spec or used 13BT.
You NEED a turbo trans, as your non-turbo transmission is going to explode in a very short while.
The NA trans can barely cope with the power of the non-turbo 13B, but once you start to go over 200hp at the wheels, it'll quickly kill itself.
Another reason to just to go 13BT swap + trans...
Now, let's get to why it's not going to work...

Keep in mind that I don't want to spend big bucks either (again, another shocker...lol). I know a lot of people run diesel turbo's and whatnot, and that may be an option.

You want your cake and eat it too...?
That's not going to happen.
Cheap will bite you in the ass.
If you can't commit to such a project 100%, you're wasting time and money - go find something else to do half-ass.
About the two best turbos that are matched to the 13B is either a Garrett GT35R or a T04Z.
Both cost serious money, but you can't afford it.
If you can't afford that, then you have to compromise.
You are not going to find a turbo set-up that'll boost from off-idle all the way to redline - either you can't afford it, or it doesn't exist.
Be realistic in expectations.
Just this fact shows me that you have no idea how a turbo works or how to apply a turbocharger for your application.
This is why said: "No."

The megasquirt works very well now that I've got it somewhat decently tuned.

Either learn how to make that thing make you breakfast, or throw that crap away and get a decent EMS.
"Somewhat decently tuned" does not cut it when it comes to forced induction.
In normally aspirated engines, you have a larger safety margin.
With forced induction, your safety margin narrows rapidly when you start to increase boost and power.
I recommend you need to be able to tune NA in your sleep before you go touching a turbo engine...
