Dear Scotty,
Curious, what is your opinion on General Motors Eco 1.5 L turbo charge motor; three cylinders; and the pistons are aluminum… Just asking for your 54 year experience opinion… Thank you.

Scotty has mentioned in his videos that both the Ford and GM 3-cylinder turbocharged engines are garbage.
the pistons are aluminum
Aluminum pistons became popular in the 1920s due to their low reciprocating mass and have been the norm for quite a few decades.
As far as I know the last automotive engine in the U.S. to use iron pistons was the Chevrolet "Stovebolt Six" (aka "The Cast Iron Wonder") introduced in 1929, where iron pistons were used to reduce cost ("a six for the price of a four"). That engine used cast iron pistons into the early 1950s.
