>The HKS website says the standard 3037 appears to come in the following:

Don't go off their website.  Give them a call.  They do have the 52T
compressor with the regular 3037; it's what both Zak and I are running.  I'm
99% the only difference between the 3037 and the 3037S is the compressor
housing.  That's easy enough to change.

>I was planning on the 52T .73 A/R which is also what Mike K suggested.  I
*thought* that was your suggestion too?

>From Rob Cadle
"GT3037: This is the mother load of turbos.  Get the 52 trim compressor and
.73 A/R turbine housing for good streetability and ~400-425 or so whp.  Get
the 56 trim compressor and .89 A/R turbine housing is you can live with a
little more lag and want ~475+ hp."

For more power you might want to go with the 56 trim and .89 housing like
Rob suggested.  Consider your goals for the car.  The 52T Compressor with
.73AR turbine housing is *a lot* of power for a street car.  At just under
3K RPM the car starts making boost.  At 3K RPM it makes 3psi, at 3500 RPM it
makes 5psi, at about 3700 it really starts to build.  Just under 4000 RPM it
makes 10 psi and just after 4000 RPM it tops out where my wastegate is set
at 12psi.

I haven't turned up the boost up yet to where the turbo is supposed to be
most efficient.  Zak, with lower compression was able to get a couple of
runs at 15+ psi.  He and I have to get our cars on the dyno to see where we
are at.

Extra goodies like aluminum intercooler piping, extrude honing, H20
injection, swain coatings, 3" exhaust fabrication, and transmission work can
really push your project over budget.  Shop around for what you can and you
should be able to save yourself some money.
