Default The 6 simple steps to reliably turbo your NA/NB Miata.

Follow the following 6 steps to properly and reliably turbo your stock NA/NB miata.

1. Standalone ECU and wideband. Budget $800-$2000. I highly suggest a MS3 of some sort with an Innovate MXT-L or AEM UEGO. Hydra, Aem, Haltech, Adaptronic also make stand alones, but there is less forum support. Install this on the stock motor and learn how to tune.

2. Buy larger injectors and install them. Retune. Budget $300-$1000. You want to get get EV14 injectors. I suggest FlowForce injectors as they are the best bang for the buck EV14's. Anything also from Injector Dynamics is good. Generally higher hp guys on here run ID1000's. You don't want older RX8 or RX7 or etc... injectors. Most RX8 injectors on the market now are fake chines knockoffs and who knows how well they flow, and RX7 injectors have shitty control at low pulse widths so idle control can be hard to get good.

3. Stronger clutch. SuperMiata, FM, ACT are the only brands you want to be looking at. Budget $300-$1000 for this. This is another place not to try to cheap out on due to how much of a pita it is to change a clutch when your shitty ebay one fails.

4. Figure out your IC setup and BOV. Budget between $350-$1000 for this. Generally run 2.5" aluminum pipe on the cold side, and 2" aluminum pipe on the hot side.

5. Buy quality turbo hardware. TSE/MKTurbo/FM/Artech/BellTuning/Fab9 is where you should be buying from. Budget $1500-$5000 for all this. Install all this and tune your fuel and spark table in boost.

6. Enjoy the stock motor and be between 220whp-250whp. At this point you will have a reliable setup that you should not have to do any major work to as far as the turbo setup goes. Now you will start spending money on engine cooling, and suspension and such to catch up to your new found horse power.

I finally got tired of typing this all out repeatably and posting it to newbs. So I made it a sticky so I can just start linking or quoting from it.

I've been wondering when you would do this.

Interesting info about the injectors. Is there a good way to tell if eBay RX-8 injectors are real, or should I just avoid them all?

Unless you pay too much to have them flow tested, you'll never know until you crack your piston.

I'm running Yellows (RX-8), but installed them before FF existed.

By the time you buy used Yellow Tops, have them properly flow tested and supplied with new rubber parts, you are at $150.

With what others have experienced with new Yellows, I would forgo them.

I would recommend going with the FF for $300.

This guy knows his stuff, he made my turbo kit and I have been happy with it for a while now. I followed the instructions and am happy.

I wish I had found these steps 3 months ago, before I started my blind journey into the turbo miata world.!
These steps really make sense!

Thanks,
Mike Mohr
