Vacuum routing diagram

Alright I've looked through all the forums. Had a slight intake popping the other morning I'm guessing vacuum issues. Other than that car's running great. There's a sensor on the firewall that looks like it did have a vac line to it. And the fuel pressure regulator doesn't have one running to it so it might be after market I'm not sure.
Any thoughts or insight would be greatly appreciated

Sensor on the firewall depending which one your looking at is the barometric pressure switch. The fuel pressure regulator even if aftermarket should have a vacuum line running to it.

with a maf conversion you should have the vacuum disconected from the map sensor.the port on the sensor should be open and the line itself should be plugged.

That is your egr valve. It is supposed to have a vacuum line from the solenoid attached to it.

Yes, and you can make a relay to fool the computer for the egr.

I have a 92 gt u bought a few months ago. The vacuum lines that go to the egr valve are capped off but the electrical connections are still made. Is there anything that I need to ck and make sure of or is this ok the way they have it. It was already like this when I bought the car.

It will run fine like it is. If you want you can make the egr mil eliminator, it's simple.

I would suggest making the eliminator.

Yes, you can remove the EGR valve and block off the hole with a plate that you can purchase or fabricate yourself.

Here is how you make the EGR Eliminator.
Solder the resistors together and connect as shown.

Well here is a ? On that same matter if I bought a new throttle body and egr spacer instead of buying the plate what size mm would work for street na motor but would also be good for the single turbo motor I'm building? Can I just put on whatever size the turbo motor needs on my engine that I have now.
