Owner reviews for turbocharger

12k+ miles later and the turbo is working great, with a single caveat. Every so often I will get some turbo surge under WOT high boost conditions.

I have a S362-SXE and I have full boost around 2700-2900 (may be earlier, I need to dig through my logs to check). I make about 600hp and 550rwhp on pump all day every day, no e85. Perfect street turbo.

The turbocharger that APR uses is an actual Borg Warner unit that they modify the housing on. We never have to do any modifying of the APR K04 or the downpipe when installing them.

I replaced mine at 96k for the same issue. The wastegate gets warped and eroded and does not build enough boost. Mitsubishi is the original manufacturer that built them for BMW. I replaced mine with the MHI (Mitsubishi) big turbo because it was literally a hundred or so dollars more expensive.

They do.

I have 40k on my car (30k on stage 2) and it's flawless.

There are IS38s that have failed under stock conditions. You're not going to gain much insight here. Some fail, most don't.

At 61,200 miles my 2020 GMC Terrain SLT had the turbo fail. At least they /think/ it was the turbo, which they replaced for a discounted price thanks to GM stepping in, since it would have been about $2500 and i was literally 1k out of warranty. 6 weeks after the turbo replacement, the car started doing the same thing, which was completely failing to accelerate.

I just had to replace my 2016 Buick Encores turbocharger with 52k miles on it. I bought an aftermarket turbo because I will not risk another GM piece of trash part.

taking it in to change the turbo charger for the third time ????‍♀️
