I see mostly disadvantages to "remote mounted" turbos.

A turbo is most efficient if you can keep the heat of the exhaust until after it exits the turbo, then let it cool. Part if the reason that in some applications the turbos and manifolds are wrapped in "blankets", or ceramic coated.

The other disadvantage it the large amount of air in the system between the engine and turbo makes for a slower response than if the turbo is mounted at the engine with as short as possible pipes.

I do suppose any sort of turbo is better than none at all, but for the most bang for your buck
I would not use a "remote mounted" turbo

When I first saw the ads for the "remote mounted" turbos I thought it was clever, and it is, but after some thinking I have decided it is about the last choice for how to install a turbo.

I have a turbo in my 48 Chevy, and twin turbos in my 61 ford, pictures on my link below.
