As engine technology improves to meet the stricter emission regulations, turbochargers face more adverse operating conditions than ever before. To accommodate this, an advancement in turbocharger technology is essential to prevent premature failure.
A good example of such advanced technology is the Borg Warner turbo no. 5303-970-0208, which fits the 2.0 TDI Volkswagen applications. This turbo has been designed with a nickel coated machined from solid (MFS) compressor wheel to avoid corrosion, caused by the EGR system. Without this coating, the compressor wheels would fail well within the warranty period.
