I will get some pictures of the waste gate.

I would think with a manual transmission, you would really need a blow-off valve. This will allow the compressed air an escape route when the throttle blades close between shifts. This is better than the air rushing back and hitting the compressor blades. You can either vent the blow-off valve to atmosphere, or plumb it back to the intake tract of the turbo (the compressor, not the turbine side,) which would give the turbo a slight help to recover between shifts. You can get a cheap and very effective BOV from 90-94 Mitsubishi Eclipse turbo cars. They are usually good for around 20-25 psi.
