Who knows. Maybe the bearings are shot, maybe there is a crack internally. Unless you stripped the turbo down to the bearings you can't be sure.

 

Do you have an AFR gauge?

 

A tiny exhaust leak at idle might be a massive gas leak under load.
You need a new manifold regardless.

 

Yea but it's not gonna be enough prevent boost completely

 

I do it will go one when my test pipe comes in

 

Please stop searching for boost until you get the AFR gauge in.

I repeat: stop searching for boost until you get the AFR gauge installed.

Then wire the wastegate flapper shut as Aidan suggested. Don't go WOT and hold it at that point, just see if it makes more boost than it did before. IF IT GOES TO ALLOFIT BOOST AT THIS POINT, GET OUT OF THE THROTTLE BEFORE YOU BLOW **** UP.

Please don't do anything else til you get the AFR gauge installed.

 

OK

 

It has a haltech AFR meter in it but it doesn't function correctly.

 

I will rephrase this for turbofan then...


Don't get into boost until you get your AFR gauge working.

 

Indeed.

Also, I realize that the AFR gauge is not what's physically stopping the car from building boost. But you need it before you build boost.

Wiring the wastegate flapper shut is the next step, AFTER a proper AFR gauge is installed and working.

 

Weld it shut, then have all the boost!



(OP- do what turbofan said, but wire the wastegate OPEN)

 

+2 for welding shut. You paid for boost. You should have all the boost all the time. Why compromise?

I'm guessing you have a shitty ebay bov leak to match the shitty ebay exhaust leak. If not that then your IAC is VTA or something.

 

There currently is no bov installed I bypassed it and the intercooler to help via process of elimination

 

If you don't place a physical barrier between the throttle cable and those exhaust parts it will melt because it is plastic. If it melts and the throttle sticks open, which does happen, you might die in a fire, which is generally considered an unfavorable outcome.

 

Pics of IAC plumbing, please?

 

Thats already been done, as well as the vacuum line. Well it is just tight up against the firewall but you are right I do not some form of heatshield. Any ideas? Dei, custom?

 

idle air control valve plumbing correct?

 

Don't ya just love figuring out someone else's project problems!

This thread needs more photos, cold side, hot side, back firewall. Your BOV bybass... errr teh thangs.

 

yea, I think its good for me. Its a really good learning process that will help me further my miata knowledge as well as automotive. As well as appreciate a well functioning turbo system. Plus by the end of this we will have a really good thread on what to do if you are experiencing a no boost condition.... I told you I would contribute to the community

 

Idle air control valve, yes. Show me where it is connected.
