You should totally get a megasquirt. It's cooler than a turbo.
I am just beginning to tune mine with rx8 injectors and stock fuel rail, regulator, and pump. At 8 psi (which is what I'm getting on wastegate spring only; no boost control yet) there is a decent amount of headroom in terms of injector duty cycle. Example datapoint: 150kPa, 11:1 AFR, 5500 RPM, 66% duty. I paid like $50 for 6 rx8 injectors on ebay. |

You say 6-8 pounds now... lol. You'll want more. Injectors - anything ~440cc or bigger. Fuel rail/pump - can remain stock if healthy. MS - yes, you'll want an EMS. |

Everything you need to know for what you want is already been written. Your setup isn't crazy or special. :facepalm: |
Downpipe depends on your manifold.
Fuel: walbro pump 190lph High pressure pump, your rail is fine Get a megasquirt, dont look back Read this twelve times: https://www.miataturbo.net/diy-turbo-discussion-14/diy-faq-all-your-answers-one-big-post-4288/ start with 440cc inj if you arent using a RRFPR inline with your fuel system. If so, use 305cc supra injectors and tune accordingly. goodluck, bye |
Manage: Megaskeet or AEM EMS
Injectors: 400+ Downpipe: Get one made cheap ass. Sexuality: Just accept your man-butt seeking nature. |

We'd need to know what kind of manifold you have to give any input on downpipe. Pictures are a good start.

Have you thought about reading the stickies? Somebody on the forum builds them cheap and will provide a nice base tune map for your injectors. If you read some stickies you will figure it out.

I think it would be best if you put a penis in your vagina.
