Trackspeed NA/NB EFR Turbo Kits - Currently Not Available
Nah that's fine, we need the repetition for the masses.
There's a lot of information on this board, it can be hard to stay on top of what's "current best practice".

The Quaife gearset is great from a ratio standpoint. It is, however, relatively fragile, especially when tracked. I autocrossed for years with no issues but when our local track opened, I've lunched two gears in two years. Heat seems to be the culprit. I'm eagerly awaiting a T5 option.
Ideally I think you want to be able to make more torque than is usable then flatten the torque curve with really good rpm based boost control. Personally I haven't experienced any really good electronic boost control that was very reputable in all situations yet.
I will say it is amazing how little you gain in autocross with more power over say A CSP car at the top levels of competition but extreme HP is still required to compete at the top levels in SSM.

On a somewhat related note, Maxxis showed the new VR-1 200tw street tire at SEMA. 245/40/15 is slated for Q2/16 release. This makes a 350whp street Miata that much more plausible. Separate thread over in wheels/tires.

Any idea on price with downpipe?
I'm so tempted to switch from my Artech purely for packaging size and due to the limitations of air filter placement in the NA (due to pop ups).

Question: If I swap out my oem turbo kit off my MSM. Will my MSM idle/run with the stock ecu?
I'm wondering because my MSM turbo is a POS and when it comes down to smog time, I'm able to run the stock ecu and tie the wastegate wide open so it will not go into boost just to get the obd2 in smog ready mode?

(looking to upgrade)
