Hi Todd,
Thanks for the comment.
Yes, the stock turbo will fit with the casting shown without a spacer.
However, I want to turn the turbo exhaust manifold 180 deg (which is possible by
grinding a bit off some edges) which would then put the exhaust of the turbo
pointing toward the rear of the aircraft rather than the front. However,
that moves the turbo over toward my side mounted oil pan, so hopefully tomorrow
will find out if it fits or interfers.
This is my third induction system and
probably not the last. Its important to get flying as that keeps the
juices going for refinements. You can refine it to the point you never get
it airborne if you attempt to get it perfect before flying.
I will need to use a scavenger pump due to
the location of the turbo on the "Plugs Up" orientation of the engine. On
the other hand all the exhaust plumbing is a bit easier, just a down pipe off
the turbo exhaust and out the back of the cowling.
Today, need to build a throttle body cap for
the cold air hose. The throttle body opening is 4" in diameter so my 3"
hose won't quite fit. Onward!

manifold running
Hi
Ed;
Looks good. Will you be able to fit a stock turbo and manifold around that
intake without the spacers? I suppose a stock turbo may not be best for plugs
up as you will still have to use a scavenge pump to return oil. Or does your
custom oil sump extend low enough to allow a modified gravity
drain?
As I'm using a turbo, I'm relying on brute force to overcome any defficiencies
in my intake design (which is very lightweight;-)), but like you I accept that
it may not be the last one that I build but it will get me flying. So I am
interested if I can fit that intake flange in beside my turbo, as it will be a
good start to build another intake if required.

Another objective was to clean up the exhaust
side of the
block for later putting a turbocharger there. As the
second photo shows,
plenty of room for the turbo now, note how snuggly
Paul's casting bolts
up..
