Are 6.0 turbos bigger or the same as 7.3? Are they considered a bolt on upgrade?

the 6.0 and 7.3 turbos are completely differnt 6.0 is VGT 7.3 is wastegated, I dont think you can put a 6.0 turbo on a 7.3

oh yeah I forgot its Variable geometry turbo. No wonder you hear it spooling more since it spools up faster.

Cool I always wandered why it sounded that way!

Actually, that ISN'T the EBPV. It's the turbo spinning. It too is normal. Expecially if you have an intake and a straight pipped exhaust.
