Turbocharger OEM Volkswagen or BorgWarner
The absolute cheapest brand new turbocharger you can buy for those engines is an aftermarket BorgWarner and will set you back no less than €1000 + shipping.
Stick with a Borg Warner replacement. Buy once, cry once. The price is worth the longevity and reliability.

After the past year and 11k miles, I remain convinced we bought the right powertrain combination. Our situation is a bit uncommon in that we live at about 6000 feet elevation (Rocky Mountains). We cross higher mountain passes on a regular basis. This definitely amplifies the advantages of turbocharging. At high altitude, the 2.0T is substantially faster than the 3.6 VR6.
The ko4 I have is borg warner.
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!
Similar here. EPC light on intermittently. Diagnosed as a failed wastegate. The fix was a replacement turbocharger.
3 weeks after posting this and my turbo locked up on the hot-side... Car ran 10 degrees hot out of nowhere and then a loud pop followed. Checked everything and it seemed okay. Except the turbine wheel didn't want to spin. Absolutely locked up. Friend driving behind me saw more black smoke than usual during the pull followed by a blue-white "puff" which we agree is when the turbo died.
They are indeed extremely fragile, the stock CKRA BorgWarner turbo is not reliable and will blow. Its just a question of when not if
The CKRA has a smaller turbo than the CJAA. The CKRA turbo is also more prone to blowing up.
