Should I move to a turbo NC?

I'm considering building an NC:
- ~300 whp trackable turbo street car with built 2.3 or 2.5 L
- rollbar for track
- maybe a PRHT?
Advantages to me, in this order:
- chassis rigidity (better NVH)
- displacement
- tire width
- better rear supension geometry?
Cons:
- looks - that hood line, and the headlights, are ugly
- cost of building?
Now my questions are:
- Can the tranny and diff take 250-300 ft-lbs for HPDE's?
- Does it have the crappy gear ratios of the NA/NB 6-speed + 3.9?
- Has anyone installed a full standalone? in parallel? What issues are there? CAN?
- Are there good cooling solutions with AC in place?
- Why don't FM make a turbo kit for it? I'm a bit leery of BEGI fitment issues

Rear suspension geometry, being multi-link, is superior. How much better, no-body is really talking, although I'm sure you could find the info. The NC chassis is essentially a shortened RX8. They're also inherently heavier (see good-wins build).
As for tuning, ANY car can run standalone, it's just a matter of how much of a PITA it is to get running. Most of the boys at M.net, are still "flashing" each other.

I'm loving my NC. A few things I've learned second hand. First, a built 2.5 with cams and all the supporting mods gets close to 300whp without the turbo. NC light has 270 whp, and dynotronics is working on a 2.7L variant which should put you right at 300 hp N/A. If you must have a turbo, I would just stick with a built 2.0, or else do a full N/A build for the same money. Flashing the ecu really is like having a standalone. You are just reprogramming the factory maps instead of an MS, it's the best of both worlds. For a track car, I'd be looking at a roll bar and soft top, the prht is heavy. From what I've read, cooling isn't much of an issue. A bigger radiator pretty much does it. The radiator is fitted on an angle similar to the rx7 and the factory ducting is light years better than my NA was. The 6 speeds are supposedly stronger, but I dont know how much. The gearing is also crazy close together. I drive between 3-4k as standard shift points and I shift every 10 mph or so. I'm sure there are beefy gears available though for the 5 speed. Don't know about the diff, but the v8 swap kits are out there making that diff a last resort. All that being said, I really love this car. Same miata spirit, but more refined. It's like a comfy miata for adults rather than the no compromise go kart that my old one was.

"Commando Package is the most comprehensive tuning software package for the 2006-2008 NC MX-5 Miata. This software allows YOU access to ALL of the timing, fuel, MAF, torque, throttle, open loop, rev limit, and idle tables/functions. This is what you will need to make the car run reliably with forced induction or for highly modified NA vehicles. It includes the interface box, cable, and software. "

Not what I think it is? This is on my list of things to buy, but maybe I should reconsider if I can't tweak it myself.
