Yep all correct in regards to the datto wagon with spazzy music
There is room for lower mount turbo setup but the idea I have is
to simplify the inlet and exhaust manifold to make it as compact
as possible yet still some distance from the bonnet for if you add
the carb sitting ontop of the normal manifold and air filter it
should leave about 10cm of space above and all thats needed is
some steel plate over the turbo or some heat proof shield with
insulation on the bonnet also to avoid buckling.
Although the inlet manifold has less volume than the exhaust it
should provide very good response.
Datsun engineers where quite smart with the inlet manifold in
having the Y split it focuses the inlet charge towards the inner
sides of the V compressing the flow in a tight "0" like shape that
would push the charge into the cylinder through the outer edge of
the inlet valve wedge wall improving centralised swirl.
Although not the best design for overall NA power with boost its
a different story where swirl type heads are improved with boost.
I have thought of using the big port 3k manifold from the toyota
however they are alot of work and not equalised lengths which do
upset the pulses compared to our beloved A series manifold.
it should like TopGears Draw through provide nice response.
The small inlet manifold volume should have no puddling.
