I installed a set of Bosch EV14 injectors in my MSM last month. They were $300 and definitely improved the idle in spite of being 640 cc/min injectors vs the stock 270 cc/min. Lots of overhead now on duty cycle, and can even consider going E85.

Corsa, I just did some digging. The miata, sti, and protege are all denso top feeds not EV14. Do you want the miata / sti fitment or the Bosch?
You can put EV14s in a Miata, but you need an adapter. We have 'em in big fat sizes.
I've got a set of red (240-ish), purple (270-ish) and a set of 270cc DeatschWerks injectors sitting in my garage without a place to be. All Miata Denso top feed fitments.

When you say fitment are you talking about the pigtail connectors? or the o-ring design at the top? would a photo of the rail help?
Alright, so, local shop that specifies in subarus let me drop by with my ITBs. Turns out... sti injectors are an exact and perfect fit. He happens to have a couple sets of STI injectors and am going to purchase them after work. I'll post an update a bit later.
You should still be able to get the sti injectors to idle, but they're double the size you're looking for (565 cc). I'm running them in my mazdaspeed.
Perhaps playing with the base fuel pressure will help with that to some extent.
Ok, update. Found the proper o-rings to get the STI injectors to fit, on order and will be here in a few days. I think I can still get them to idle, and they are indeed overkill but everything else I've found so far is under what I'd like, and I am hesitant to go with injectors that are a tad small and end up in the heavy duty cycle range, or risk burning them up.

If the ECU is up to it, you should be able to get them to idle... I'm running 320cc injectors on my 4AGE - stock are 210

I ran 850cc in my Galant VR4 and stock were 450. Stock FPR and with a chipped ECU on a 25 year old computer. Running slightly bigger injectors for a tuning cushion is going to be fine with the modern computers in ECU's these days.

I'll be running megasquirt 3 and the resolution is way better than ms2 or ms1 so I think I'll be OK.
Test fit with both injectors on the rail minus o-rings which will be here in a few days.
Still enjoying following along on this build! I'm right now in the process of starting to tune my own ITB'd engine with an MS3Pro. I don't know much, but I am learning a lot about injector dead time when tuning for idle, and the best scaling of the load axis for idle and off-idle tuning with ITBs, among other things. I hope to keep learning, so if you get to the tuning point and find yourself stumped, feel free to hit me up and we can put our heads together.

I'm a very large fan of megasquirt, but I get a lot of E36 M3 from a few of my friends because they'll only tune AEM or Motec, so they've straight up told me, "If you do megasquirt I won't tune your car." Whatever.
However, I might just hit you up if I get stuck somewhere or something along those lines. I love this forum because people here love to help each other and this is a very friendly community where the DIY types are embraced, not shunned.
Pump, reg, y block and the rest of the goodies on the way. Does this look sound? I feel like this is going to work just fine.
Pardon my mspaint skills.
I'm a little worried about the filter before the pump, but it looks good.

Well, there is always a in tank filter before the fuel pump.

Not really a filter just a screen to keep the big stuff out of the pump.

Exactly.
Well, there's no screen on the tank, I suppose I could do a large screen instead of a filter. I suppose as long as I clean the hell out of the tanks before going with it I could probably just do a screen. Just want to keep the life of the pump good. It just needs to keep the large crap out and be easy to clean if necessary.
For Halloween I'm going as a social recluse that smokes cigars, stays at home, and works on his lambo because more car parts. Sadly, my GRM vinyls haven't arrived yet, so I can't add one to my rear window to gain the +20hp I need.
Alright, bay 1 is finished. Will do bay 2 tomorrow. Super tired. Long monday. At least I got something done on the car.

most intank fuel pumps have socks....
but since you are running an inline pump... https://www.aeromotiveinc.com/fuel-filtration/

Good info, thank you. Currently fighting motivation issues, didn't do any wiring last night. November and December are going to be long months for me. Trying to scrounge up the motivation to actually get stuff done.
