so i am looking to order my heat exchanger this week. i have been suggested to get the fan option which makes sense. my question is i was told it might be a good idea to go 1" barb fittings over the 3/4" stock.

what hoses need to be changed? will there be any other restrictions that need to be upgraded so the system doesnt flow as much as the smallest hose?

i am looking at the weaponX heat exchanger. i have seen the afco for similar pricing with fans. i am open to suggestions. mods below and car will get a cam and e85 next year.
