That seems strange..... you can blow up about any engine by upping the boost enough and never touch a port LOL. Since the turbo impeller is a huge exhaust restriction and has a specific map, then it would have to be a pretty extreme setup to think of porting for most car engines. I ran 1.75 HP per ci on my 2.6L Starion engine and that was with just 14-15 psi boost... serious, but no where near an extreme amount of boost. Never touched a port.
Does this friend deal with truck turbos? If so, that is not generically applicable advice. they seem to have some pretty restrictive parts to start with.
