That sounds like a good solution, but it is not what I really want to make
sure of.
I already have one of Richard Sohns RX-8 oil adaptors and a meter adjuster
plate. This allows the oil injection system to vary oil rate injection
based on RPM, which means the electronics are no longer required.
What I want to ensure is whether adding an extra oil injector or injectors
into the intake system for 2-stroke oil injector would be a good option or
addition. If it is, then where is the best place to add them or it in the
intake system, the stock manifold is being used for this project.
I thought this might be a fairly elegant solution. The RPM of the engine
controls the flow of 2 stroke oil that is injected. I've attached the
adapter information that Richard provides the prices in are out of date
I think.

That RX8 oil metering pump adjuster is a clever idea Richard.
The best place is inject it into the fuel on the low pressure
side of the fuel pump. Mount the oil storage container high and use a
needle valve to control the gravity flow into a T in the fuel line.
Probably a better idea is to use a venturi in the fuel line so
the oil flow is proportional to the speed or amount of the fuel flowing
through the fuel line.
Putting the oil in the fuel also means it lubes the housing better
as it is automatically distributed through out the housing.
BTW it is by no means certain that low apex oil injection caused the
problems
with the early RX8 engine apex seals. The current thinking is failure of one
or more ignition coils caused misses that washed away the apex seal oil with
too rich raw fuel.
If you mix the oil with the fuel this cannot happen.

Looking at the picture are you suggesting it be gravity feed into the
fuel line?
Would it not be better to add it into the fuel line under a little
pressure from the Oil
Injection Pump System?
Wouldn't that be a better option it would also make sure it mixes more
accurately with
fuel as it is being used and vary the amount based on engine RPM.
I guess a one way valve would be need to be installed ensure no back
flow of fuel into
the oil system not an issue to install though, apart from that I think
it would work.
So it would have force feed oil into the line, yes?

It at depends on the positions of the respective tanks.
It is easy to mock it up and see what happens.
