A Plan Thatcham branch - they have a special modified vehicles department. I've also got a v8 Defender project which is with them as well, they are pretty good at mirroring NCBs between the two cars

Good to know, I was using Need2Insure for my RX-7 which was on a classic policy for around £200. Only needed to state the power output as a result of mods, otherwise all mods were fair game. They wanted over £500 for the Eunos as it stands now. 
Will check out A-Plan, I was with them when I had my MR2.

The whole point of miata guys running EV14 injectors is that the idle quality / drivability is still ok. I think you'll be fine.
The point of doing the fuel pump first is one of priorities. You want power? We all want power. But do you want to run your motor lean and destroy it, and then have to rebuild it? That is why we are here, and reading posts such as yours. Edit: stock USDM fuel pump runs out of fuel ~190whp. Best to replace it now with a more robust unit, I recommend DW300.

Regardless, a 1.8 NB will go up far more than 190 if you swap injectors. It's boost referenced fuel pressure, so if you have larger injectors you can make more power. I was fine with the FF's at 230 or so on the stock NB pump. I just swapped to ID1000's and a DW200 for some more headroom.

DW300 will overpower the stock system in the US. I wonder if it works with the EUDM cars because they have a return fuel system. I'm not sure. EDIT: JDM car, not EUDM. Same thing.

Yes. The post I quoted said that the NB fuel pump runs out at 190 whp. He hadn't mentioned anything about injectors changing that, which is why I was clarifying that (which I'm sure he knows as well).
From TSE regarding the DW300:
Again, nothing new to folks here, but mentioning it in case the OP wasn't aware of this.
From TSE regarding the DW300:
DW300 only:
- The DW300 will overpower the factory fuel pressure regulator, resulting in poor idle quality and driveability at low loads. We strongly recommend using an aftermarket fuel pressure regulator with the DW300.
- The DW300 is capable of drawing more amperage than the stock fuel pump wiring can provide. To adequately supply the fuel pump at very high flow and pressure rates, a secondary relay and dedicated +12v feed is required.

To the OP - as it's a JDM/non US car and not a mk2.5 - I think you may already have a pressure referenced fuel system with a return. Any chance of a pic of the inlet manifold? / fuel rail & pipes?

Reading through on this i just thought i'd weigh in on a couple bits.
My old NA8 ran the ME221. Solid enough performer, though the tuning software left a little to be desired. When i bought my current NB-RS, i decided i wanted better, so sourced an MS3 Mini from MSLabs through Bofi Racing (who also sell decent EV14 injectors too). Direct fit on my NB, including working clutch switch for launch control & flat shift.
I'm currently amassing my turbo setup which is also Kraken based, albeit with a 2560R as i'm in no rush to push block limits!

Given the cost of the MS3, I'm considering going Adaptronic Modular. Adaptronic's owner has had a number of MX5s of various years and the support/feature set is great.
Must admit I'm also considering going GT2560R rather than EFR for the same reasons as you!

Unless i've missed something, £600 for an MS3 vs £1200 for an Adaptronics seems like quite the OTT purchase?
Edit: Ah that was a fitted price, £750 seems to be about the typical price for that Adaptronics i see? For what it's worth, i'd be more inclined to stick to MS or ME for the very simple reason that 90% of the MX tuners in the UK use those two and nothing else. For me, going back to MS was because there's also FAR more knowledge around on that, meaning i'm not locked to one tuner/vendor etc.

OK the pricing I'd found for the MS3 was $1100, is there a UK supplier or did you buy direct from the chap in Greece?
EFI parts do the modular for £1200 fitted and mapped. Something that appeals.
