finally going to turbo my Miata
Hello everyone I'm new here and boy do I have a lot of questions. My 91 Miata is stock. My goal is to get around 200whp. I'm planning to do this starting now and hopefully be complete before summer is over next year.
I want to buy an ECU and EV-14 550cc injectors. My plan was to get this soon so I can learn how to tune. My first question, I was going to buy a MSPNP2 then I came across diyautotune's website now I'm thinking of installing their MS2 w/PCB3. Has anyone tried these? Next question I might be able to pick up a 94 Miata with blown engine for around $500. Is this drive train heavy duty enough to support 200whp do I install the tranny from the 94 also? I've read that the 1.8 NB's can handle up to 400whp but can the NA1.8? Well thats enough for now any help would be greatly appreciated.

I've seen a plethora of questions about DIY MS2's that don't start, and people questioning what mods need done and such. If you want to cheap out, get a DIYPNP, it's a straight forward build and will drop right in a Miata harness. If you were willing to drop the coin on an MSPNP2, but can read instructions well and can solder, get an MS3+MS3x (see guide on trubokitty.com). MS3 opens up a lot of possibilities, and just plain runs better than MS2, due to it's speed and driveability adjustments. If you just want it to work, get an MSPNP Pro.
Other than the diff, basically all NA and NB's have the same torque limits. The rods go around 250 wtq, 5 speed at 250 wtq, and 6 speed at 300 wtq. Those numbers will go up or down based on how hard you use it (ex: endurance racing will lower the limits significantly, where some people can push 300+ on a 5 speed by driving easily on the road).
Just keep reading. Make sure you're 100% confident about every step in the tuning and turbocharging process before you do anything.

What does the ms3 have that the ms2/extra doesn't. I'm pretty clueless trying to read about these ecu's. Diyautotune doesn't remanufacture ms3's anymore. They build the ms2/extra. I have no clue if this is as good as the ms3.

Good: MSPNP2 $800
Better: ms2 enhanced from mslabs ~$800 (more features than mspnp2)
Best: ms3 basic from Trackspeed (also made by mslabs) $1099
pick one, be happy. All will make car run just fine, from mild to wild turbo setups.
ms3 will be easier to get day to day quirks worked out for closer to stock car behavior.

Brain still sells the MS3X and it costs significantly less than the 1400 number you made up.
The only time I'd consider a MS2 is if you're 100% certain you don't want to use EBC (bad idea) and you don't want vvt (shrug). I'm not sure if the rev based unit is any different for these factors for the MS2, though it very well might be because he's a wiz.
