I should have stated that it is a 4000 series.  Sorry about that.  So,
unfortunately ;-(, I have no turbo.

Thanks,

Hi Cade,

What you're describing is a characteristic of the K26 turbo.  No boost

below 3000 rpm combined with the low compression ratio of 7.8:1
combines
for soft initial acceleration.  If this bothers you greatly, locate a
K24
turbo.  Its a straight bolt on.  You'll need a chip to go with it, but

you'll get great acceleration starting at 1900 rpm.  The trade off is a

slight loss (about 2-5 MPG) of fuel economy and a drop off of boost at
the
high end if you track the car.  This is the so called heat soak
phenomena.  I myself don't notice this, but then I seldom race my car.

HTH,

Tony
