Well, I found that like anything else the Plugs up installation has its
pros and cons.
However, the only real con was the lack of vendor support for Plugs Up.
Having the exhaust outlet on the bottom simplified plumbing, also reduce
chance of fuel from injectors falling directly on a hot exhaust. No
problem with flooding the engine. I did it a few times, but 4—5 revs of
the engine pumped all the excess fuel out the exhaust ports and of course the
spark plug holes being on top did not collect fuel. It also provided room
under the cowl for longer intake runners – don’t know if that would be the case
with the 20B, but assume it would.
All in all, if I did it again, I would use plugs up everything else being
the same. Oh, yes, much easier to change the spark plugs {  }
I did have to modify Tracy’s PRSU mounting plate slightly – moving the
starter position.
Good luck on your decision, Bobby – more power is always hard to resist

Looks like a good arrangement.
I’m still on the fence as to installing the 20B I purchased a few weeks back. If
I do make the swap I’m considering plugs up as an option.

Found
this old photo of the bottom of the oil pan which may help. The blue
fitting is naturally the drain hole at the lowest part of the
sump.

Thanks Ed. The standoff is not
visible in the picture but I had guessed you did something similar. Any
issues with sealing the oil pickup tube to the block off plate and front
iron?

Oil System
I
believe the things you have the arrows pointing to are triangular shaped braces
that support the oil sump to the oil pan. The are welded to top of sump
and plate.
To
access the bolts in the area of the sump, I stood the 4”x 4” tubing I used for
the sump off from the pan about 1 – 1 1/2”. I did this by using a 1” x 1
1/2” rectangular tube (its end’s plugged) welded to both the plate and the
sump. Then 3/4” dia (I think around 6 holes) holes were drilled
through plate, standoff and sump for the oil to return to the sump – probably
best to drill holes before welding components together, but they can be drilled
from the inside plate side – just make sure you get all shavings out. This
stand-off also gave you access to around 3-4 pan bolts. Depending on your
set up these may or may not be a pain to unscrew, but it can be
done.
The
round tall blue tube served as oil fill tube and dip stick tube. It was threaded
internally at the top and a threaded plug with a hole drilled in it for the dip
stick was used.
The
aluminum tubes were coolant (front) and air/oil separator (which I took off
after two years of flying with it and it collecting no oil, because the rotary
simply was not spitting any out.

[FlyRotary] Questions for Ed Anderson- Plugs UP Oil
System
Ed,
I have a couple of question about
your plug up installation. How do you access the oil pan bolts located behind
the oil reservoir and allow for oil drain back? Also I see what looks like an
additional tube (black arrow) in the attached photo. Can’t figure out what it’s
for. Is it a support bracket?
Thanks,
Bobby Hughes
