That turbo is too small on the turbine side.
.50 A/R is way too small, engine won't breath.

Did you find what Snowman used for a turbo?

This is something like snowmans turbo http://www.ebay.com/itm/Universal-GT35-T...f2ed441&vxp=mtr

The turbine wheel is a little small but it should work OK for you also.
