6.1L Hemi with T56 build

Looking for some help and narrow down info into one thread for myself.

I was going to install a 5.7L into my Duster but found a 6.1L for an amazing price.

I have just a few things I need info on.

Starter - T56 - I'm thinking mopar mini starter
Headers - 6.1L - TTI for AlterKtion
Wiring and PCM - Hotwire? Does anyone know if my 5.7L PCM can be flashed for the 6.1? Remember I don't need it to control the trans.

Any other info anyone want to pass over?

Thanks,

Riddler
