ko3, ko3s, and ko4-015 sizing.
Since people here LOVE to talk about upgrading to a ko3s and ko4, i thought you guys would like to actually see the size differences. That, and im sick of stating the differences almost monthly
Ko3 - 97-2000
COMPRESSOR WHEEL
Inducer: 33.6mm
Exducer: 46mm
Tip height: 3.7mm
TURBINE WHEEL
Inducer: 45mm
Exducer: 38mm
Tip height: 6.8mm
Blades: 11
Ko3S - 01+
COMPRESSOR WHEEL
Inducer: 38mm
Exducer: 51mm
Tip height: 4.4mm
TURBINE WHEEL
Inducer: 45mm
Exducer: 38mm
Tip height: 6.8mm
Blades: 11
Ko4-015
COMPRESSOR WHEEL
Inducer: 35mm
Exducer: 50mm
Tip height: 3.7mm
TURBINE WHEEL
Inducer: 50mm
Exducer: 42mm
Tip height: 6.4mm
Blades: 11
As you can see and have been told, the ko3s has a larger compressor wheel than both the ko3 and ko4 along with a more effecient design. However, the ko4 has a slightly larger turbine wheel which makes it able to flow the higher power made by chipping better. The best thing to do if you really want to go this route is to buy a ko4 AND used cheap/dead ko3s and swap the compressor wheel and housing to the ko4. This should net you a few more whp and tq

You're the mod, make it a sticky
Here's a cool sheet of what engines a K03s came on (by engine code):
