Hello everybody im new to the site. Ive been looking at this site for awhile. I have a 95 7.3 powerstroke that i truly love. Ive had her for a long time and dont plan on ever getting rid of her. The question i have is. Has anybody ever put a 6.4 turbo . On a 7.3 as a secondary turbo

 

Could be wrong as I dont know much about the 6.4, but arent they VGT turbos? You'd need a way to control the vgt. I know it's been done with a dial in the cab using a 6.0l turbo.

Most people will suggest you just replace the stock turbo if you want more boost. Twin turbo'ing isnt all that popular.
