Spec of the turbos as follows:
*TD High Flow massive 88mm custom billet compressor wheel (62mm inducer)
*CNC machined compressor housing with custom/modified larger inlet neck
*High flow 9 blade huge 63mm turbine wheel upgrade (58mm 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 better results than straight 99 octane.
