Spec of the turbos as follows:

*TD High Flow massive 77mm custom billet compressor wheel (62mm inducer) 

*CNC machined compressor housing with custom/modified larger inlet neck

*High flow 9 blade huge 65mm turbine wheel upgrade (60mm inducer)

*CNC re-profiled turbine housing with ported and polished manifold inlets

*Upgraded 360 degree thrust bearing assemblies

*550+ Bhp 

Please be aware to get the full potential out of this turbo we recommend a minimum of a decat/sports cat, FMIC upgrade, 97506 plugs, panel air filter, MST turbo inlet, custom map and a minimum of upgraded fuel pump using 99 octane pump fuel.

Higher octane from methanol injection or a ethanol mix in the fuel tank will obviously also yield higher power results than straight 99 octane.

If you wish to send your stock turbo back please send it back within 2 weeks and well packaged
