Regarding the complaints about engine noise in the back seat , I had a
similar problem
when I had changed the air filter system and did not have the sound
insulated snorkle
connected.   The intake roar of the diesel is loud and the stock system
has a fabric pipe
with sound baffles on the inside of the tube that runs up to the air
intake in back of the
rear window on the right side of the car.   Since the fabric pipe was
damaged, I used
abs fittings and 2 1/2" dia straight radiator hose up to the vent.   It
was more acceptable after
that.

My impression of NA vs TD engine noise was not a signifcant difference
but the power
difference is noticeable.

Good Luck,
