You may reconsider..
How much HP can K26/6 max out? - Rennlist Discussion Forums

Standalone is NOT cheap, and street ask the work and running you go through, I would hate to see the turbo be your limiting factor. It's old technology, old design. There are much easier ways to see 300. The k26/7 from the turbo S wasnt that far off already, and can easily get there. Or there's the Lindsey kit.
If youre going to spend several thousand on stand alone ems, and 1000+ on a raw tune, why cheap out on the turbo? I knew I was going to spend a lot, so I figured I would do it right the first time and spend less in the long run.

Copy and paste specs:

K26/6:
Compressor housing :
ID intake 1-13/16"
OD intake 2"
OD outlet 2"

Compressor wheel :
Inducer dim. 1-3/4" (44mm)
Major dim : 2-9/16" (64mm)
= 46.63 trim

Turbine housing :
Inlet ID 1-15/16"
Outler ID 1-7/8"
6cm2 = 0.366 cu in A/R

Turbine wheel :
Exducer dim 2-7/16" ( 54mm)
Major dim. 1-7/8" (48mm)
= 59.17 trim
------------

My choice of Borg Warner EFR6258:
Compressor Type: Forged-Milled Wheel (FMW) Extended Tip
Compressor Wheel OD (exducer): 62mm
Compressor Wheel Inducer: 49.6mm
Max Flow Rate: 44 lb/min
Built-in BOV: All EFR compressor housings incorporate an integrated BOV.
Compressor Housing: 2.5" inlet, 2.0" hose coupler outlet.

Turbine type: Low Inertia Gamma-Ti Turbine Wheel
Turbine Wheel OD: 58mm
Stainless Steel Turbine Housing
0.85 A/R v-band Housing (external WG)
Turbine outlet: GT-Vband (aka small 3" vband) ~92mm OD
