I don't know that too many people have chose that particular turbo for an IDI
I ran HX35's on both my 01 and 92 Dodges and both could easily push over 30psi with the smaller 12cm exhaust housing
... Very quick to spool without having excessive egt's. I like how much aftermarket support there is for the HX series. I ran several different sized exhaust housings (9cm - 21cm) wastegated and non gated and eventually settled on the 12cm for both of my 5.9 powered trucks.
Again I'm not an expert, but I'm thinking that with 7.3 liters of IDI furry a larger exhaust housing (~18-21cm) would be needed to reduce drive pressures. I have not attempted the math on one, but I think a HX 35 would be a lot of fun on an IDI and work well if you had the fuel and were not worried about lifting heads... They seem to be popular on the 6.2/6.5 builds.
Did you have a design in mind? I think the pedestal would be the most difficult part
EDIT: Also you would want to drill the housing to allow both sides of the manifold/up pipe flange to vent. The HX series only vents on one side
