In reality, with a Holset large enough to make it worth while you'd never fit it between the engine and the firewall, you'd need to mount it over the bellhousing of the gearbox with a custom manifold.
You'd need to move the battery into the boot to stop it being cooked, but you could brace the turbo from the gearbox which would be handy.
Routing the downpipe would become, erm, interesting.
Probably best to run it straight out behind the near side front wheel. This would be noisy.
