Any ideas or info?

There are no shear pins, there is a key to hold the gear on to the shaft as it rotates. It is not possible for the key to come out with the cover on, and the gear in place. It is not a large key, so it just slides down the square hole on the right gear. You can pull that gear out to inspect it.

Those gears look mint.

Did you pull the gears out at all? If the motor is running there is absolutely no reason for a rebuild. I have never seen one of these fail.

I agree but the key is not there; not really sure what happened. I only checked out the pump with the bottom on so I am going to try today to check it out with the bottom off and see if the motor works. should the gears be rubbing on the back plate?

Never bothered. In my case it was post popping the motor. I had small debris inside but nothing big. However seeing my oil pan I can guess that something big may have gone through. My problem was a circlip. But the pump itself is a good product. The worst oversight I made was not getting an inline filter to save it. The inlines were on their site. With my new one it runs like a top and I think the other one would've too barring me blowing the motor.

Mine came with an in-line strainer

Neither of mine did and I have two. The one from Sasha and the one direct from Turbowerx.

I do have one as well. It's just weird that i cant find the key like were did it go?

Hey guys how do you take apart the waste-gates for cleaning? I took off all the screws on the top and bottom and it will not separate. A little advice is needed please!

May be binding ....try tapping it with a rubber mallet or something that won’t damage it ...there isn’t anything internal that holds it together

I’ve never taken one apart, but dumb question, is the spring out of it?

Boosted Performance · 01-22-2019, 01:15 AM

Unless the gate is malfunctioning, there is really no reason to take it apart. Once the crews are out, there is nothing else holding the top cap in place. So be careful as the spring can send things flying once it does become loose.

Now that were on the topic of wastegates.. I'm still having overboosting/boost creep issues. I spoke with my tuner and he sent me an updated map. Fixed the problem for a day and then started overboosting the next. I know it's not a cold weather issue because its been happening all year.

I've seen alot of other platforms having boost creep issues with the external tial wastegates. I could be going down the wrong path here but has anyone swapped to a different wastegate completely and has anyone else had this issue? I spoke to solidus about this and he said his wastegate spring pressure was not rated for what tial claimed when tested. Even if that's the case. Shouldn't the tuning keep the boost pressure from going over? I'm not the most knowledgeable when it comes to turbochargers so I'd appreciate any help or advice

I'm having a vacuum pressure test done just to rule out any type of vacuum leak.

You trying pulling apart your wastegate?

solidus · 01-22-2019, 04:01 PM

The springs test + or - 1 to 2psi. What Realstreet does is test each spring they install to match the rates. As far as taking the wastegates apart I use a C-clamp then slowly release it. Unless you want to see parts fly. Put it back together the same way to avoid crossthreading.

I have not. Tomorrow I'm bringing it to shop for a vacuum pressure test. Might as well have them take a look while its there.
