Turbocharger OEM Volkswagen or APR

Yesterday I tackled the IS20 installation. It took about 4-5 hours and overall wasn't too difficult. The car definitely feels better. It should've come like this from the factory!

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.

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

Mine has over 200k now, still running the stock turbo. I will probably keep this car for awhile.

After the stage 1 APR tune almost immediately roasted my IS12's wastegate, I'm about 4 months into an APR stage 3 IS20 setup. Aside from a persistently unenjoyable power delivery, the car's been reliable so far.

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

My IS12 turbo's wastegate failed. Thankfully, it was replaced under warranty at 57k miles, even with a stage 1 Apr tune.

I just replaced my 2015 TSI 1.8 after it lost all compression on #4 cylinder. It is IS20 turbo with the APR tune.

I’ve had water pump failure, AC failure, windshield wiper motor failure and an oil leak due to the turbocharger on top of your normal tire, brake, rotor, windshield and oil maintenance.
