Spec of the turbos as follows:

*High Flow massive 82mm custom billet compressor wheel (66mm inducer) 

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

*High flow 9 blade huge 68mm turbine wheel upgrade (62.3mm inducer)

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

*Garrett roller bearing assemblie

*700+ 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 HPFP fuel pump using 99 octane pump fuel.

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