Our latest turbo's from Holset are called the VGT for Variable
Geometry Turbo, this turbo does not require a waste gate and is capable of
producing 30 p.s.i of boost at idle which is close to 60 in.of hg.. It has a VGT
controller that is controlled by the ECM which sense the boost pressure and
delta P sensor for the EGR to
function at all conditions, we can eliminate
the EGR portion.
That does sound perfect,
but I have to wonder about availability, and price. The plain old everyday
turbo that Mazda sells for the 2nd gen is about $2k. The 3rd gen twin
turbo is >$3k. Neither of these come with electric vanes, or
computers to control them. I would be afraid to ask the price of a
complete VGT setup, if they would even sell it as a
system.
Cheers,
Rusty
