Oh boy. Another one of these threads.

My take on the situation aligns with Ben's.

The turbo is not spinning. It is a cheap shit turbo that you shouldn't have bought, but that's a problem you will have to sort out later.

Your vacuum lines sound like they are all messed up. There shouldn't be any interconnection between lines associated with the carbon canister and the boost sensor and the wastegate control. And certainly not power steering. Either you have described them wrong or there seems to be something wrong about the way they are set up. Either is not good, but the latter can lead to problems. Get it straightened out before proceeding.

If perchance the turbo IS spinning, then I place money on the wastegate being jammed open.

ahh okay.

as for the turbo outlet and the wastegate T's into a boost pressure solenoid and another hose comes from the solenoids top that goes nowhere atm i think its a bleed hose? maby it was hooked into the original frontmount pipe?

get a picture of that.

youve got it setup wrong if im reading that right.

the nipple on your cooler piping should go to the wastegate actuator.

completely disconnect the boost solenoid if its the factory one. (if its same as 33)

edit:im going of the info you have provided, not my hatred for chinese shit. is the turbo isnt spinning at all its dead.

be back with photos

Not really worth the trouble. Even with the boost controller hooked up wrong it will still make boost. It can't swing the wastegate open magically somehow.

Might as well show the photos so when you bolt your next turbo on you have correct boost control

Back! everything seems fine now the wastegate was jammed open im so happy

That's good. What about the oil restrictors and the bush bearing turbo? That's a bad combo.

And are you sure your boost control lines are plumbed correctly, or don't care cos car goes now ;)

ok im transferring pictures for the boost lines, yea that oil restrictor worries me now but it did seem to flow oil when i had the oil out pipe off when i first cranked the turbo without starting car

ok so i think the pipe that goes to nowhere is supposed to go into the turbo air intake between turbo and airflow meter, can i hurt the car not having it on? btw thats the boost pressure control solenoid pictured above this post

The carbon canister hose should go to the plenum via an ECU controlled solenoid (located at top rear of engine) that is only opened when the ECU says it can be opened. If it goes direct it's not right, but it's not going to cause any problems with the turbo etc. Something I would fix if it were mine though. Although.....that purge solenoid will only work with the factory ECU (or a Nistune thereof). Won't work with aftermarket ECUs unless carefully set up.

The wastegate plumbing is basically fine. The unconnected hose that is supposed to be connected back to the turbo intake is simply the vent. It works whether it's connected or not. It's just an emissions violation if it's hanging out in the breeze.

Does that mean you have boost?

If you do - drive it very carefully. It's a somewhat larger turbo than the stocker, and the stock ECU will cause you problems if you boost it up. You will run into R&R which is where the higher load parts of the factory maps are deliberately "tuned" by the factory to give yo shit performance. And the ECU has a boost sensor connected to the crossover pipe near the BOV that will cause a very hard boost cut if you overdo it.

      New fix for low tyre pressure from bmw

      I had never actually looked into it, but aren't onboard compressors a thing in trucks?

      Anyone have this problem with their temperature gauge?

      By sunsetR33 · Posted

      Read the ECU for fault codes or have someone else do it. A faulty coolant temperature sender is usually listed in ECUs. If the sensor itself is not busted it can also be a bad ground connection. Or in a really unlucky case, damaged wiring.

      Anyone know this frontpipe?

      By sunsetR33 · Posted

      Can't be a Futjitsubo as those are made with a flex piece and Reimax is smaller in pipe diameter. If anything it is closest to a Mines pipe, but evidently it is not an actual Mines pipe.   Classic word humor

      Alright I will try to not forget.   As GTSboy replied to you already, problem is mainly the mismatch between the actual exhaust part and the denomination in the papers. That basically just looks like tampering to a cop, if they were to check your car and notice. If it had been done right they would have clarified it to be a custom pipe and just given it a certain part number that you have to engrave or weld onto the pipe. I will definitely inquire on what to do. Changing the pipe wouldn't be my favorite solution as it costs a bunch of money and the cat was fitted with the front pipe and exhaust under the car, and if the front pipe flange does not sit in the OEM location the cat will need to be refit for any other pipe to work. It also usually doesn't need a brand name or something like that, but more something like a part number. Usually for exhaust parts, on silencers and cat units specifically, there is a badge that reads the certificate number that belongs to these exhaust parts under EU regulation. You get these numbers after you put a part or group of parts through the tedious testing according to EU vehicle legislation and they pass. You can find these "part numbers" on various parts throughout a EU vehicle. On windows, headlights, engine parts, seat belts and so on. All these parts have gone through standardized testing and acquired a so called ECE or EG Certificate that makes them legal to use by themselves in all countries that adhere to these standards. You can also not alter these parts in any way, if you do they become illegal. An example for stampings on an exterior lighting part, the people who need to know can find the documentation for this unit in a database. I do not know what all the standards and so on mean.

      If that was the case I suppose you could call it "Mein's" brand....  ... I'll see myself out... 😅
