Looks like the turbo is bolted straight up to the hole on top of the exhaust manifold (where it heats the original inlet manifold) and the carby mount section of the inlet manifold has been chopped out to make room for the turbo;Then 1-2 and 3-4 manifold sections have been swapped around to allow them to be spliced back together with rubber hose from the turbo.
A lot of thought has been invested in this set-up and even though it may seem a little crude, there is no reason why it should`nt work.
Good luck with your project
