I don't think this is a run of the mill model. I can't seem to find anything about it. Does anyone know about this series?

Could it possibly be a T04B H-3? If so there is a map for it at this link, which is also under the turbo stuff sticky.

The only other this I could find is that it is OEM on the Cummins 833 Heavy Duty.

Thanks ATO. I did a little more digging and I came up with the same info as you. It is not a Garret but is for a big truck like you said. So it is not what I need.

I have been to that site and is very informative. Another one I found is: http://www.sn95.com/projects/turbo/part1.htm They seem to have a very simple sizeing calculator. When you plug in your VE, compressor and intercooler efficiency are the numbers best guess? Through different calculators I have come up with a T04B v-1/v-2, which has a VERY different map compared to the 60-1 that is included in the INCON LT1 kit. Can you help me plot out some points so I can choose the turbo a little better?
