Before I get flamed for "There are better kits out there" I picked up a Stock greddy kit for $200. Ive also been a member for almost 10 year and have been researching and reading. I am not in need of a high hp miata just want to liven up my daily. I lucked out and found a guy selling a basic greddy kit for cheap and that where I am starting. I plan on just running the stock greddy kit (no intercooler) for now. I also picked up a MS2 PNP and have RX7 460cc injectors (I have 3 RX7's these dont leak for now)

1. Which should I start off with first the MS or the Turbo kit? I am still reading about the MS2 and I dont even know where to begin Im still reading.
2. If I do the MS first do I need the FMU or just use the MS to control stock injector (I feel like I need to add a walboro or increase the injector size)

Im still reading up on it now. But wanted some input for you guys with more experience. Thanks in advance.

No you haven't. No one with even 3 brain cells would ask questions that stupid if they did even a few minutes of browsing/reading of this forum. But then you did buy a greddy kit so.........

Perhaps take some time to do some actual research and reading?

Both Im just overwhelmed with MS reading. I see it does control everything that would negate the FMU. Just not sure about the stock injectors and the base kit.

I guess Im just really asking if I should learn about the MS first and start with that or install the base greddy kit.

I've had the Greddy manifold (with relief cuts) and matching Mitsu turbo on the car for 70K miles. Nice 10psi DD solution for a 1.6. ~190RWHP.

Do the MS first. Go ahead and throw on the RX7 injectors and tune for that. Once you've got the car running well with the MS and larger injectors, you can install the turbo. IIRC, this is basically what I did years ago.

Toss the FMU. Stock fuel pump provides plenty of fuel when you use larger injectors.

If I had a do-over, things I would do right from the start:
1. Inconel studs.
2. Coolant reroute.
3. Intercooler + ducting.

And that is exactly what I was looking for.

It's written hundreds of times around this site, first thing is to install a megasquirt and tune it, that's why you are getting some flames.

I'm not trying to straight contradict Hornet, but I would recommend just installing the megasquirt by itself, getting the car running nice, and then install the injectors, and tune again.

My reasoning goes like this...
First, if you are running into problems, you aren't trying to figure out if it's the MS install, or the injector install that you screwed up.
Second, it gives you an extra practice at tuning, so that when you try to tune for the turbo you are slightly less likely to screw it up when it matters.

I think that is what hornet was saying, just didn't space it out and specifically say that. As others have said work on tuning with megasquirt on an all stock car first. Makes it easier not changing too many variables at once. Most base maps will get the car running for the most part with barely any changes. Then you can work on fine tuning and learning as you go, it's scarier than it is hard in all honesty. There are plenty of threads that will give you a step by step on tuning idle, fuel, and such. Just gotta dig a little
