lol I was kinda joking with that one.
The easiest way would be to do the test I mentioned with 1 wheel on the grass. If you go anywhere, it's a torsen. If you don't, it's open.
2) you definitely don't have a 1.6 torsen diff.
because they didn't make them, the 1.6 diffs are open or viscous-lsd (aka "almost open"). You would 100% know for sure if you have an open diff and you tried to do mad tyte doriftoing, you will get a bit sideways and then just not go anywhere because 1 wheel spins. I can "drift" in the rain (with lift oversteer), but the car will NOT powerslide, if you get on the throttle too much or too early in a corner... well... nothing happens. You just bounce off the rev limiter without actually going anywhere.

So I noticed the instructions for the SC are on Goodwin Racing. They're out, but say it's the same kit as FM. The instructions on Goodwin warn against reflashing the ECU, but there is a cautionary statement on FM saying engine management is needed. So which is it?

I havent done it too much, because i dont like buying tires, OR putting my car into the wall. But, i do have to "flick" it into the turn, which it holds and handles quite well. I dont do it often enough to know for sure, but it DEFINITELY goes into a drift/slide with ease. I need to crack this thing open... hell, maybe its welded... it just doesnt act like its welded when i make a tight turn (ie: inner tire skipping/chirping)
ANYWAYS.... IN for awesome NC POWA!!!!!!!!!!!!!!!!!!!!!

I guarantee that it wont hold a slide with static controls for more than... 100 feet or maybe 150.

I'm thinking the FM approach will run about $6,000 for the SC package (ECU Reflash) plus clutch, mid pipe and muffler. Add $1,000 or so for the install and I get ~230 hp at the wheels for just over $7,000? The install looks pretty straightforward and it looks very professional when in. I lose the warranty and a couple of miles per gallon. I get a 2500lb/250hp daily driver that delivers a very smooth torque curve, decent mpg, great handling, and great reliability.
Am I missing anything?

Earlier, in my reference to limited budget, I had thought that you were shooting for $6k with installation and tuning, and with the more expensive NC options out there I thought that sounded pretty tight for a turbo kit. And it is. But $7k for the supercharger, while still lots of $$, will get you where you want to go!
Good luck! Make sure to post before and after pics and stuff!

Again, thanks for the feedback and tips everyone. I got to thinking last night, always dangerous, and did some more number crunching.
It looks like the BEGi system would cost almost exactly the same as the SC assuming I equip it comparably, reflash, exhaust, clutch. I'm thinking the install would cost a little more. I would end up with probably 30-50 more WHP, maybe a little more maintenance, and an upgrade path (which I don't need) for about $6,000 plus install. And Turbofan won't laugh at me, can't forget that!
The TDR system will come in as the most expensive at $6,200 including reflash and exhaust, but no clutch. So throw in a clutch from somewhere else and it looks like about $6,600 plus install and horsepower at the wheels will be similar to the BEGi.
Sound right? Other than doing the install myself (no way) I can't see how to get a lower cost without buying used.

Haha what? I won't laugh at you? Good sir, I will not be laughing at you no matter which way you choose to go, since you'll be the one driving around in a FI Miata, something I'm currently lacking!
That being said, to go turbo on a BEGi kit for the same money... That's the way I'd go. There are more things you'll need to watch, but if the installation is done correctly and carefully then it shouldn't be any less reliable than an early 90's RX-7, wouldn't you all think?

There is a fellow on mx5atlanta that goes by mxgeorge who has a very nicely done 2006-up turbo car. I don't know the details but it is a daily driver and it runs STRONG. And it has been running a turbo for at least 4 years that I know of. Perhaps his was done by a shop local to you and might be a good answer for your needs. A kit might not be as good an answer as a local shop that builds the components in house (just like BEGI and FM do) and has been there and done that before a few times.
I wish you the best with your search.
I wish you the best with your search.
We actually talked yesterday about his setup, if I understood correctly he's now using a combination of a flashed ECU along with the Xede that came with the turbo kit from BEGi. The flash took care of some things that the Xede couldn't do and the Xede allows on the fly adjustability that a reflash doesn't.
I'll point him in the direction of this thread though and he might have some insight to offer from his journey through the boosted NC world, although this thread has been plenty informative. If you want to test out a turbo NC before making your choice, he's a real friendly guy and I'd bet he'd be happy to accomodate, it's a good way to make sure you'll be satisfied with the investment. (We might even have a local NC owner with FM's s/c too, can't recall right off, would be very easy to post on the local Miata forum, mx5atlanta.com, and ask.) I'm also not a shop, but depending on your timeframe, I'd be happy to help with your install should you not be satisfied with your quote from Mazcare.
Last note, just so you know we have an awesome exhaust fabricator here in Atlanta: Jason @ EnthuzaCar. His exhausts are sold by most of the Miata vendors out there, so going directly to him (he's near Dobbins ARB) can save you some time and money, and it supports him directly.

That was my point. He said that other than the 90k engine rebuild he was satisfied with the reliability of that car. This car should be no less reliable with a turbo so it shouldn't be a problem.
