I was tying this exact response, you beat me.

One who cannot afford to go out and buy 500 bucks worth of injectors, cannot afford a turbo miata.

 

I bought the car with the turbo kit already on it, I'm not saying I cant afford the injectors, I'm just asking if I can RUN the car until I find which injectors I should buy, order them, and get them installed.

 

Yes you can run it. You will need to wire the wastegate flapper in the open position and hope that you do not have enough boost creep with the flapper open to go over your available fuel. The system will likely still generate a pound or two of positive manifold pressure. As has been the case before, sometimes you will end up with 8 or 10 lb of pressure even with the wastegate all the way open which is why people are cautious in their advice to you. Set your overboost protection at 4 or 5 lbs on your megasquirt.

 

Alright thanks for the info

 

The previous owner already ran it on the voodoo box for a while I'm assuming, so it's fairly safe to say you can drive the car without too much worry.

At wot, how many psi do you get at say 4-6k rpm?

 

Yeah the previous owner drove it all the time (atleast he said he did)

8psi @ WOT

 

This makes it sound like they either already put in larger injectors or put in an aftermarket fuel pressure regulator and just cranked the base pressure way up (or did super janky **** like crimped the return line from the regulator). There's no way stock injectors at stock pressure can hit 12.5:1 at 8psi.
