Have a Nice Day? Question About 2.5L Hybrid Build

I just spun a rod on my factory at about 90,000 miles sad but now I guess its time for the 2.5 bottom end. My questions are first off

- What difference will I see in gas Mileage?

- Will all the pumps and pulley's switch over to the 2.5 L Block?

- What will I have to watch out for on my transmission with the Torquey block?

and anything else you think I should know would be great.

bryancregger your thread is lacking several key details...
What type of car. 2.5 NA dohc, 2.5 NA sohc or 2.5 turbo?
Which bottom end are you trying to swap? Are you keeping your old heads?
