Turbochargers remain one of the most sought-after performance upgrades among South African car enthusiasts. Whether you’re building a street car, drift car, drag car or dedicated track machine, a turbocharger can dramatically improve performance when properly selected and installed. However, with new turbochargers often costing tens of thousands of rands, many enthusiasts turn to the used market for more affordable options.
Buying a used turbocharger can save a significant amount of money, but it also comes with risks. Understanding what to look for before purchasing can help you avoid costly mistakes and ensure you get the best value for your investment.
Why Buy a Used Turbocharger?
Many performance enthusiasts upgrade to larger turbochargers as their projects evolve. This means quality used units regularly become available on the market. A turbocharger that no longer meets one owner’s power goals may be perfect for another enthusiast’s build.
Used turbochargers often provide access to premium brands such as Garrett, Precision, BorgWarner, Holset and Turbonetics at substantially lower prices than buying new.
Key Areas to Inspect
Before purchasing a used turbocharger, it is important to inspect the unit carefully.
Shaft Play
A small amount of shaft movement may be normal depending on the turbocharger design. Excessive movement, however, can indicate worn bearings and potential rebuild requirements.
Compressor Wheel Condition
Inspect the compressor wheel for signs of damage, chips, cracks or contact with the housing. Damage in this area can significantly affect performance and reliability.
Turbine Housing
Check for cracks, excessive corrosion or evidence of previous repairs. Minor surface marks may be acceptable, but structural damage should be avoided.
Oil Leaks
Oil residue around the compressor or turbine housing may indicate seal wear. While some leaks can be repaired during a rebuild, they should be factored into the purchase price.
Ask the Right Questions
Always ask the seller about the turbocharger’s history. Important questions include:
- How long was the turbo used?
- What vehicle was it fitted to?
- Has it been rebuilt?
- Why is it being sold?
- Are there any known issues?
The more information available, the better equipped you are to make an informed decision.
The Importance of Correct Sizing
One of the most common mistakes enthusiasts make is purchasing a turbocharger based solely on price. A turbo that is too large or too small for your application may deliver disappointing results. Factors to consider include engine capacity, intended use, fuel type and horsepower goals. Matching the turbocharger to your build is critical for achieving optimal performance.
