Can someone help me with building my first diy turbo?
As far as your concern the MS3 you buy should match the year of the wiring harness in your car. So since you have a 1.6 NA, you want to buy a MS3 for a 90-93.
The actual MS3 ecu can run anything from a chainsaw motor to a v12. You can buy a braineack MS3X put it on just about any gas power motor in the US. The PNP ones not so much as most of them are adapted for the specific wiring connectors in the miata. You could theoretically open it up and change it, but its not worth even thinking about it.

Start searching. If you can't find that you are going to have bigger issues long term. You also need to start reading a ton more. You should read every sticky thread in every section on this site. Then you should go read 4-5 pages back worth of build threads. Then go read everything in the megasquirt section.

The megasquirt has to match the wiring in the car. If you stick to the 1.6 harness, you should be fine, if you install a new engine harness, you will need to swap MS harnesses as well afaik.

Makes sense. I think I'll just stick with my 1.6 for now. Or at least until it blows up

Man, getting busted up in this thread. 
A 1.8L is nice but not mandatory. It all just depends on your end goals. I have had really great success with my turbo 1.6L, winning my regional class in autocross and now doing HPDE events. It's fast enough for the chassis and the grip I get out of super 200s and budget Bilsteins. If you have the budget then go for the 1.8L and then turbo when the funds allow. All the other advice you have been given is great and should really be followed as best you can. Also, if you go to that 3.9 rear end (and still NA) with the 1.6 you are going to notice a sizable loss in overall acceleration. The 1.6 just doesn't have the torque for it. I built an RX7 diff for mine with a 4.10 and it was awful. Even with the slight power increase on Megasquirt.
I have a Youtube channel that goes over some of what it takes to turbo your 1.6L, as well as some setup items with MS2. Spring for MS3 if you can afford it. I built this thing about 4 years ago and wish I would have gone with MS3 now. If it was a daily or more than a HPDE/autocross car then I would have switched over to MS3.
