You've understood how they work, now you must think about "when" they work to understand why they're there. A turbo utilizes the exhaust gas to spin a turbine which which is mechanically coupled to another impeller on the intake side which forces air into the engine. As the engine produces more exhaust, the turbo spins faster and produces more boost until ...

It really depends on which part is sticking. If I've reconnoitered your turbo correctly, it has a built in wastegate. If it's the wastegate which is sticking and not the actuator, then you're wasting money by replacing the actuator (the turbo replacements I've seen for your engine come with a new actuator). You need to verify which part is at fault, ...

This is an opinion question, so you may get varied answers. This is my opinion. In my experience, I have found it is always best to start with the simple and work toward the difficult. In your case, I would start with the wastegate before going to the expense and difficulty of changing the turbo itself.

Porting your wastegate allows increased flow rates through the gate itself. The gate is a little metal flap (operated by a vacuum operated actuator) that covers a small hole in the rear of the turbo housing hot-side (exhaust side).. The flap usually extends past the diameter of the gate port/hole so that no air can leak. When the flap opens, it allows ...

While the engine is not under heavy load, it is highly unlikely that the turbo will spin up enough to cause sufficient pressure to require the waste-gate to open, so in neutral it will definitely not open. It is highly likely that you would need to be doing a decent amount of acceleration before the waste-gate opens. While monitoring the boost pressure in ...

If you can purchase just the wastegate actuator, I would do just that. It's bound to be vastly cheaper--if you can buy it separately. They are not difficult to replace--assuming you have room enough to replace just that. If you have to remove the turbocharger first, it adds to the labor and time but still you will likely come out ahead. You can also inspect ...
