My 08’ NCV3 2500 needs a new turbo, according to my mechanic. The symptoms: loss of power, and a rattling/clicking noise coming from the engine bay/turbo area. Said to be an actuator or wastegate solenoid of some sort. My mechanic suggests replacing the entire turbo, which is fine but, they say it’s a 4K$ turbo. After asking around for some other opinions I’ve found a suitable turbo for much less. My questions are these: what is the deal with that particular turbo being so expensive, and who can I trust to install a turbo and still hold the warranty that comes with that turbo? I’m in the Seattle area so anyone who’s got some local info would be greatly appreciated because my current mechanic seems to believe that expensive option is the only option. I’ve done a little searching and found some suggesting that there may be holes in the intercooler piping. I haven’t found any. I’m also curious about what gaskets or hoses may need to be replaced while doing this service. If I go about the job myself I want to know I’ve got all possible bases covered. Thanks to anyone in advance for providing information.
