Here at GCG Turbochargers Australia Pty Ltd we pride ourselves on having the BEST turbocharger overhaul premises in Australia.

This is related to every job our workshop produces, and the quality and attention to detail is second to none. Our technicians have over 100 years combined experiences in rebuilding, custom building and fault diagnosing turbochargers from all manufacturers around the world. Our work boasts the latest state of the art machinery as required and used by OEM’s around the world, this machinery is critical for a manufacturers specified repair on any turbocharger.

Our fully equipped machine shop ensures that all processes involved in custom building, re-building, and assembling a new turbocharger such as, machining, grinding, honing, profiling and welding, are all done in house, ensuring the quality is to the highest standards.

What Turbochargers Do GCG Repair?

GCG repair turbochargers from numerous vehicles on a daily basis, with the a huge variety of performance, passenger, commercial, heavy industry, transport, agricultural and marine applications. We are limited to repairing VNT (Variable Nozzle Turbine) turbochargers, as these are primarily new replacement units only (non repairable).

How much does it cost to repair my turbocharger?

Our base price for a repair is $850.00 Including GST, and this price is applicable to a turbocharger that goes through the standard rebuild procedure, that is:

  • Strip
  • Clean
  • Quote
  • Test Actuator assembly
  • Fit Standard Rebuild Kit
  • Rotating Assembly Balance
  • Re-Assemble CHRA
  • VSR Balance CHRA
  • Assemble Turbocharger

In 99% of cases, we will strip, clean and inspect a turbocharger, and find it requires more parts or machining than a standard rebuild. Some turbochargers require the following processes to meet service requirements:

  • Worn Ring Area - Turbine end ring area machining
  • Worn Ring Area - Compressor end ring area machining
  • Honing of the bearing housing
  • Grinding of the wheel & shaft assembly
  • Sleeving of the turbine housing (to repair corrosion mainly seen on marine applications)
  • Removing broken studs and heli-coiling bolt holes
  • Supplying a replacement actuator
  • Re-welding V-Band assemblies
  • Supplying a new compressor wheel or turbine wheel
  • Supplying new bearing housing
  • Supplying a new core assembly (CHRA)
  • Supplying end housings (turbine or compressor housings)

These above processes and parts will incur an added cost on top of the $850.00.

As Performance turbochargers are modenising and design is improving, the major components such as compressor wheels, turbine wheels, end housings and ball bearing packs are becoming quite high in cost. Unfortunately, this means in many cases a major repair of a Garrett GTX, GTX GEN II, or Borg Warner EFR turbocharger can be quite costly, and is more than likely going to be more feasible to buy a new CHRA, Supercore or Complete Turbocharger.

Warranty:

  • All repairs are returned with a 12 month manufacturer's warranty, and a 10 step re-fitment sheet to assist in preparation for re-fitting a repaired turbocharger.
  • Any Turbocharger with electronic actuator control (ie: stepper motor) carries a 3 month warranty on the electricla components.

What to look out for during re fitment:

When a turbocharger requires a rebuild, it is highly likely that an external source has contributed to the damage/wear & tear. The common issues we see are dirty/contaminated oil (un-serviced vehicle), oil starvation (blocked oil feed line) and foreign object damage (something entering the compressor or turbine side of the turbocharger).

These issues need to be rectified prior to re-fitting a rebuilt or new turbocharger, as there is a chance the new/rebuilt turbocharger will prematurely fail. If the shaft is heavily worn and scored, and our quote analysis shows the cause of the failure to be oil contamination, the oil feed line would be the first part to replace, and then the engine will need to be analyzed for the cause of the blockage (sludge in the engine causing blocked oil feed line, inline oil feed line filter is blocked etc).

A blocked or dirty oil feed line is a sure way to destroy a turbocharger in a very short period of time, as is oil starvation, so make sure the engine isn't part of the problem before re fitment of a new or rebuilt turbocharger.
