Ok, I have a 90 miata.

I purcahsed a down pipe and manifold off good ole EBAY. installed on car.

I am using a eclipse 2g t25. installed on manifold already.

I am using a 1g dsm bov

I already got my oil lines and intercooler piping and intercooler. Installed

I am using a na rx7 maf it flows better. So i am told anyway about 200cfm.

Anyways I have no idea on what injectors to purchase.

No idea on what to do about managment. What's the easiest way for me to get this car on the road safely?

I am only planning on running no more than 7 psi.

The stock wastegate on the t25. Is it higher than 7 lbs? If it is. Is there a way i can lower it?

thanks

For cheap managment, go with an S-AFC or better yet E-Manage.

A lot of people have good success with Adjustable RRFPR's with Miatas.

A turbo miata is gonna be my next project :P

 

I can get an safc. I am just not sure on how to tune it...Is it hard to tune?

Could you give me a rough overveiw on what i would haft to do?

Do i need a wideband setup to tune it?

I like your s13! Is it Ka-t? I would like to turbo my s13 as well. But the miata first. The s13 is my daily driver. Mine is a green coupe.

thanks

 

 

So you guys are saying.All i need is a safc? And then hook up wideband and thats it?

 

run an fmu and push 20psi people do it all the time with no problems.




just kidding yea i would get a safc and just have it tuned on a dyno.

 

Mint another mazda turbo.....

For injectors rx7 ones and cheap and pretty readily available and for some nice cheap fuel management you can actually adjust the vaf meter for the bigger injectors.

 

I think if you go with an RX7 MAFS and RX7 330's it will supposedly idle well. I hear the stock ECU has problems idling big injectors, even with AFC/Emanage.

With Emanage ultimate you can run larger injectors
lots of peeps have great success with FMU's believe it or not. One guy ran like 116 mph with MAFS, injectors and FMU only.

Here's a decent miata turbo board -

Yep, it's a KA-T and its green now as well.

 

isn't there some way to get a turbo calibrated maf n bigger injectors like johnny wants to on his stang? or is that stangs only?
