Even if gassers became turbocharged by default, just like Diesels nowadays, it's worth to consider the cost of replacing a damaged turbo or upgrading it. There might also be some issues with thermal managementt of the engine. A cast-in turbocharger could maybe increase oil temperature through heat irradiation at the cylinder head for instance.
