Turbo Repair – A turbo repair is exactly that, a repair. Your turbo has failed, so an internal part is broken or worn. A turbo repair is finding the damaged turbo component and changing it, nothing more. It’s the cheapest turbo fix in the industry. The turbo unit is operational again and everyone’s happy. How long a turbo repair lasts is an impossible question to answer, it’s simply how long until another worn turbo part fails.
Reconditioned Turbo or Turbo Rebuild – A turbo rebuild or reconditioned turbo is where the complete turbocharger is completely stripped to each turbo component. Each turbo part, including Compressor Housing, Turbine Housing, Compressor Wheel, Turbine Shaft and Wheel, Bearing Housing, Heat Shield and Seal Plate are inspected for wear and damage (this also includes the VNT nozzle variable vane assembly on VNT units) and then dimensionally checked to be inside OE tolerances. If not, then the worn turbo parts are scrapped and replaced with new replacement turbo parts. In ALL situations, ALL the turbo bearings and seals should be disposed of. A reconditioned turbocharger should NEVER be rebuilt with used turbo bearings and seals. Once all turbo parts being reused are confirmed to be good to go again, and worn turbo parts are disposed of and replaced with new replacement turbo components, then the turbo rebuild can commence, including balancing and turbo actuator calibration, resulting in a newly reconditioned turbocharger.
Remanufactured Turbo – A remanufactured turbocharger is where the complete internal workings of the worn turbo are replaced with BRAND NEW turbo replacement parts. The only parts to be reused are the turbo compressor housing and the turbine housing, along with the vacuum or electronic actuator. The internals commonly known as the Turbo CHRA or Turbocharger Cartridge is replaced. A Turbo CHRA / Turbocharger Cartridge is the complete assembly and includes a new Compressor Wheel, Seal Plate, Bearing Housing, Heat Shield, Turbine Shaft and Wheel as well as ALL new bearings and seals. This turbo CHRA is balanced and tested for noise and oil leaks before being fitted to the cleaned housings and then, finally, the turbo actuator is recalibrated.
This is basically the difference between the various works that can be undertaken on your turbo. Any reputable turbocharger company will tell you exactly what your turbo repair, rebuild or remanufactured turbo has had replaced and what hasn’t. A remanufactured turbo for as little as £100 should set alarm bells ringing. In what can be a minefield in getting your turbo back to life, and the average person being unsure as to what they are getting for their money, many choose a Brand New Genuine Turbo instead for peace of mind.
