Can anyone advise if this is a good setup.

Evo 4 Block.
Standard - With Free flow exsaust . Usual K&N Filter Thing happening there.
Evo 5 / 6 / 7 CPU.
Evo 7 Turbo - ( This is twin scroll titanium core , correct ? )

Is this a suitable /-/ Possible setup.

What would be the recommended setup, if this is not the optimum configuration, using mainly factory evo parts (This make her insurance compliant)
Also whats the story with bolting an evo 7 turbine up to the 4's manifold.
And can anyone suggest a good way to test a turbo before purchasing thats not currently attatched to a 280 HP motor.

Apart from taking it down to the local mechanics.

Sorry if I've hit up the wrong forum.

Cheers.
