Damn savington you're making it sound like an incredible ordeal. I'd like to add water injection, knock sensor, 650cc injectors and a bigger turbo and shoot for 300whp on my 1.6. I'm pretty positive it's been done before.
Just don't beat the crap out of your drivetrain.

You don't HAVE to spend big bucks to get there, but if you want to be there for a long time, you'll have to do it eventually.

That's because you'll break your half-shafts/axles before the 7" diff.
Just a reminder (and I'm often guilty of this myself, as I, too, get caught up in the horsepower figure): It's torque that kills the tranny, half-shafts and diffs., not horsepower.

Bigger turbo, more boost, good tune. The '94 1.8 is the best stock motor to do it on. A torsen is fine at 300 whp. Nobody's breaking ring&pinions on the torsen. Your axle will go first if you're launching on a sticky track.
ak47bravo,
The reason you were pinging and overheating at 14 psi is because the GT2560 is just making hot air at that boost level. It's maxxed out pretty much. An EWG will give you some more efficiency but the compressor is still too small.

I'm building a 1.8l '99 Miata and shooting for around 380-420whp and around 250whp for the streets at all times and just switch between.
IDK what you would have to change - the things others told you about are the ones.
I'm putting in forged Wiseco pistons, Crower rods, ARP head and main cap studs, SC50 turbo (I'll see how this handles and maybe upgrade to a SC61 later if this one will spool fast), MS-I v3.0, T-II Tranny, Diff, hubs, 3" SS exhaust, Egual Length Runner exhaust manifold, dual feed fuel rail, Custom intake (later), 255lph Walbro FP, 780ccm injectors, alcohol injection.
...you always have to be a little scared of your car just to keep yourself safer.

It's so much harder to hit that 300 number that IMO until I have a ton of cash to really do it right (2.0 stroker, GT3071, lots of boost, racegas, etc.) it's not worth it. Stock will support 220 forever, but the stuff that's required to hit 300 will support 330, 350+. Consider that.
93 octane
1.8 motor with stock head and intake
9:1 compression
$200 cheap chinese turbo
Stock transmission (yes, my '99 came with a 6 speed because my car was painted blue at the factory.)
Stock Torsen
296 RWHP @ 17 PSI

Well I'm just pretty used to the speed of the car, still will get me a little bit sometimes though. Only car I've driven that really scared me, is my friends 350z. 3000 lbs. @ 535 whp.
Only problem is if I go with a bigger turbo, won't I need a new Exhaust manifold?
I guess I could try to pick one up from BEGI. Could a DO WI tie in with the link ECU? I was talking to a friend and he was saying that with my new radiator I'm getting plus maybe pistons and DO WI, I really wouldn't have a problem getting to about 300 whp.

AK WI wil help you a ton since you have the link and already have fueling sorted i see no reason why 300whp on stock motor cant last for a while till you get the $ for some pistons and rings etc. I know what you mean about the car is predictable but sometimes we can get used to power that is why i keep a slow vehicle around to recalibrate my *** dyno from time to time.

I've had a turbo miata and hes had everything from a turbo celica to a turbo miata...

ak47bravo,
The reason you were pinging and overheating at 14 psi is because the GT2560 is just making hot air at that boost level. It's maxxed out pretty much. An EWG will give you some more efficiency but the compressor is still too small.
