the hx55 was common on the 8.3 big rig Cummins.................here is a pic of one

as a single turbo I dont think you would have enough fuel to lite it bro..............as the bottom on a set of chargers it would be OK

 

on the bottom it would be great

 

if its a 17cm housing with a lot of fuel you would be fine... they are a 65-67mm inducer turbo... you can take a S400 housing and get it machined to fit on it so you can run a smaller housing and not have such a laggy charger... it would be a great performance turbo but street characteristics arent that great...
