Product Improvement VNT25 (June 01, 1999)

We wish to advise you of some product improvements to the range of turbochargers supplied as original equipment to the Fiat Auto Group, These are all used on the new 2.4 litre common rail 5 cylinder DI diesel engine.

The shaft wheels assemblies have been upgraded to high temperature Inconel wheels and the compressors now use a larger wheel which is to a brand new design. These changes allow the performance of the engine to be maintained whilst lowering the rotating speed of the turbocharger.

We have changed the part numbers for the following applications:

  • 454150-0003 replace by 454150-0005 - Alfa 156 & Lancia Kappa DI
  • 454150-0004 replace by 454150-0006 - Alfa 155 & 156
  • 701900-0001 replace by 701900-0002 - Lancia Kappa JTD

Please note that for turbos 454150-003, 454150-0004 and 701900-0001 we will be unable to supply either complete turbos or any of the parts for them. These turbos must be serviced using the new part numbers shown above.
