I removed the heater box clamped on the exhaust manifold as well as the tube
which carried warm air to the intake. This freed up enough room to install a
sheet of thin aluminum which starts at the spark-plug heat shields and curves
down and ends up in the chassis next to the turbo (the bottom edge of the shield
just sits on the sill). It basically encases the hot part of the turbo but the
front is still open to allow for air to enter into the enclosed area.

My main reason for doing this is to the reduce the temperature in the engine
area in order to prolong the life of the cables and soft parts as well as
cooling the air intake.

Are there any potential problems with this heat shield? Is it possible it will
trap too much heat in the turbo area or reflect too much heat back to the
engine? Any downsides to doing this? I will be removing it every so often just to check the turbo area.
