Why bother at this point?

I smell burnt toast. Someone please help me.

wow very helpful! thank you so much guys! -_-

Simply connect it to your open valve cover nipple. One problem solved, no oil fumes on your turbo

okay call me retarded or whatever would that actually work

only one way to find out

Depends on how much blow-by you have, I guess

What problem are you actually trying to solve?
​​​​​​​Ok, you're retarded. What else can we help you with today?

That’s your wastegate, go to “google” and look up how wastegates work and wastegate routing

Ok @steaknnshake here's the deal...

There are a whole bunch of reasons you aren't getting "helpful" replies, I'll break them down for you

1. This is a forum, not facebook. This is not Vietnam, there are rules here (more like guidelines) that you have completely ignored. I'd recommend you to go to the Meet & Greet Section and start a thread. Tell us about yourself, your mechanical aptitude, your car, your cat, whatever. Post pictures, we fucking LOVE pictures. We consider this a community and we'd like to get to know you. I know you didn't do this because your join date Feb 2021, you have 3 posts, and they are all in this thread.

2. You told us fuck all about your car. I had to click on your user profile just to find out you have a 1991 Miata and that's literally ALL I KNOW at this point.
You didn't tell us what engine is in the car,
you didn't tell us which turbo you are using,
If this is an off the shelf kit or something you welded up from random plumbing fittings you found in your parents basement.
We don't know what you are using for management: boost control, fuel or timing

3. The only things I CAN tell from your pic is you have what appears to be a hood dump pipe, there appears to be a wideband sensor in it that is sure to die a quick death, and your valve cover breather isn't hooked up and you have no goddamn air filter. All of these things are fairly ignorant and we tend not to tolerate such stupidity around here.

4. You haven't told us what the actual problem is, nor the steps you've already taken to try to fix it.


Let me give you an example of the kind of content we expect:

Now compare that to the post you made and see if you can tell the difference.

Believe it or not but we are more than happy to help but you need to put in the effort. Go make an intro thread, be friendly, post some pics, relax, enjoy, then come back here and try again.

Welcome to Miataturbo.

You're a good man. With time :giggle:;)

I hope he's coming back to us

Bonus clue.
EO2K actually just told you how to solve all of your problems if you read his last reply carefully. At least, as far as any of us can tell so far.

Chinacharger with an up-pipe and no intake filter. That's how you know its the fastest drift missile in the neighborhood.

I was kinda hoping he'd come back so we could figure out exactly WTF was going on here, but if OP isn't willing to provide basic info how the hell are we supposed to help? :dunno:

even with the wastegate actuator totally disconnected, it should still make boost to what ever that wastegate is set too. likely like 7psi.

if its making zero boost, he has other issues probably not related to this actuator.

Its got the boost signal going to the bottom of the wastegate, which makes me think they were trying everything possible to hold the wastegate closed, thinking thats why it isnt building boost. The real reason it isnt making boost is hard to say.

Maybe the turbo is shot... Might have something to do with rain and acorns falling into the exhaust side when it sits, and then rocks and sand getting sucked into the compressor side when its being driven.

I think it's bird shit. Bird shit does these things...

Imagine all this shit in your downpipe and o2 sensor

To answer the initial question; yes that nipple is normally connected to the high-pressure side (outlet) of the turbo, either directly or via a boost controller. It is there to actuate the wastegate to stop the turbo over-boosting.

I'd be more afraid of some asshat pouring a bottle of water or dropping a handful of pocket change down the exhaust side. Not that I'd ever condone such activity, of course. I wonder if it even has a turbine wheel anymore?
