All GBT turbochargers come standard with a red anodized compressor wheel, black anodized backplate, water cooled bearing housing and milled compressor housing with anti surge channels. But there are also a lot of options to customize GBT turbocharger according to any concepts.

As a special option the following options can be ordered (on request):
- Air cooled bearing housing (+119.00 €)
- Silver anodized compressor wheel with silver anodized backplate
- without Highflow / Anti Surge

The Product:
The range consists of three frame sizes: 54mm, 61mm and 69mm. This figure is the largest diameter (inducer) of the turbine wheel blades. The second two numbers refer to the compressor wheel exducer diameter (e.g. GBT5471 would be a 54mm frame with a 71HTA compressor wheel). The compressor cover sizes have individual model names: Ma3, Ma5 and Ma7.
