My Subaru’s turbo is only active in colder weather. I live in Southern Africa where it rarely gets very cold. This car has been imported from Japan. The highest octane fuel we can get here is 95 octane. Can anybody help me with some idea where to start looking for the problem?

No Recalls or Technical Service Bulletins were found when searching for Turbo related issues.
That is odd since the turbo works off the exhaust system. The Turbocharger may be going out.
