i have 3 simple questions.

1. how can one hide the sound produced by the bov?

2. how can one hide the sound produced by the wastegate?

3. how can one hide the sound produced by the turbo when spooling?

 

Throw an intake tube/filter on the turbo. Not only will that quiet down that 'spooling' sound, it also provides you with a place to recirculate your blow off valve. If you recirculate the wastegate dump into your exhaust and throw a good muffler on there, it'll be fairly quiet.

 

I second that motion. Air filter will quiet things down, so will recirculating the bov and wastegate. A type r muffler would be very quiet for the little restriction it would cause. If you want to be really slick you could make a factory-type heatshield to cover the manifold and turbo, paint everything black and run the intake tube through the stock airbox and intake arm. At first glance you won't even be able to tell there is a turbo on there.
