What is more efficient?

what are your plans for your car? what is your goal? what kind of power levels are you looking for?
in general, turbochargers more efficiently produce extra power, since they don't have parasitic loss as a result of a drive belt as superchargers do. They produce power from exhaust gases, in essence, meaning they are recovering and using free wasted energy.
However, this is a rather broad question you've just asked. The answer depends on what sort of driving you do.
For instance, a turbo would be best suited for WOT applications like drag racing, and high-rpm driving such as on a road-course. However, you might find it a bit laggy when autocrossing (although, proper turbo selection and setup goes along way in reducing that). For that, the instant-on boost of a roots style supercharger may be better suited.
Your overall power goals make a difference also, in terms of driveability.

If it's a kit, the supercharger will be an easier install, however, turbos are better suited and give better results than a SC on a small motor.

depends on the type of blower. Also, the whole "belt drag" thing doesn't mean anything. If the car makes 100hp and you add a SC to it and it makes 200hp how much power is "stolen" by the supercharger? none. It GAVE you 100hp more. Was it as efficient as a turbo would've been? would the turbo have given 120hp?? maybe but the supercharger belt drag didn't COST you anything.
common misconception.

But it's not making 200 hp thru the whole range. You might be giving some up on the bottom. It's the same reason people give up their AC pumps and change pulleys to reduce parasitic loss. Why loss power if you don't have too.

now you're talking area under the curve and you don't want to fight that battle. we're comparing peak power to peak power. You can't say a power adder COSTS you anything when it adds it...and NO it does not create a horsepower loss in lower rpms. It's a CONSTANT gain.

^^ exactly. Power delivery is everything when driveability is concerned. peak numbers are for dyno/bench racers.

why 400hp? 400bhp? 400whp? Why not just focus on making it as fast as you want to go? If you want an 11s quarter mile why would it matter if you accomplished it with only 275whp??
It's things like this that really highlite the fact that maybe you need a bit more guidance with your project. You don't have any details worked out at all.
If you want 400hp you'll surely need a turbo but don't expect to get it on a stock block without spending a TON of money. Try for something more reasonable...like 250whp.

A friend built a '94 R-Package with 360hp at the wheels. His problem was putting the power to the ground... just couldn't make use of all that power... and it wasn't a stock block.
Another friends stock 1.8 web bye-bye after 75,000 miles under a supercharger then a turbo.
And you should probably be doing a lot reading on the Miata Power List - http://www.miatapower.net/

as always dana is the voice of reason
Here is an idea, find the biggest turbo, T6/T7 should work well, you can find and slapped it on to your miata. I bet you can get 400hp to the wheels quite easy, who care if it lag like crazy on the street and it will probably blow up your engine within a month but heck you have the 400HP you are looking for on the dyno right?
As for S/c and Turbo go. S/C will acted more like a larger displacement N/A engine where it will give you instant power when you stepped on the throttle but it will tapper off. T/C's power will coming in after its initial lag so you need anticipate the power coming on but without a doubt it will prodce the most HP. Both have its advantage and disadvantage. If you want to go crazy you can alway consider the dual charger set up. It has been done before. this where you have both supercharger and tubro installed

hey, i've heard that the supercharger from the stock mini cooper S (i think is eaton m45 or something) fits great on 1.6 NB's. anyone knows anything about it?

Get the M-62 from the Cobalt.. It's better for a 2.0L

m-62? isnt that a bit big for a 1.6L ?
