Not quite understanding.. 15% is high POE?
POE is inferior to PAO? What about their 0W-30 grade? 5W-20? 0W-20? (10W-30?)
Do thinner oils (SAE xW-20, xW-30) do better at high RPMs?

Yes, 15% is a very high POE content. I don't know the POE content in the other viscosity grades of the Red Line High-Performance oils, but I expect them to be similar.
POE is not normally used as the primary base stock in the base oil, as it's very polar.
Okay cool. Thank you for helping me understand.
I really rather like Redline oils, I understand some people don't like the (new) product?? But if there is anywhere I can look at different grades. I'm thinking I want to do as thin as possible, but thick as necessary, as it sounds like I will have a hard working engine.
I my opinion its good oil. But I'm simply not going to pay twice as much or more for oil that dose not give me double the documented engine life. Its just that simple.
That's a good reason to compare the VI when look for oils for a high revving engine, and don't go for ones with a huge viscosity index.
How can going to a different engine size yield a higher RPM?
Engine size has ABSOLUTELY NOTHING to do with RPM at a given speed. And Neither does the flywheel.
That's all gearing and tire circumference .
EJ engines hate pennzoil. I would run the Subaru Idemitsu 5W30 or M1 5w40 or Valvoline advanced 5W30 or EDGE 5W30
Is the 2 litre JDM engine a DOHC with AVCS (VVT) ? If so stick to OE viscosity recommendation.
My EJ253 is AVLS so they don't care about viscosity and want a near 40 grade to be happy.
I've owned 9 Subarus over decades. And BlueSubie on here is a Subaru Guru with turbo experience.

Read my previous post.
Going to that little 2 liter is not going to be "fun" or "good"
I Just hope it gets you from A to B.
And the ECU definitely need a different baseline program. - absolutely NO doubt about that
I don't see the fascination with "JDM" Unless its a car like the Skyline we don't get here.
Your old EJ253 was Made in Japan.
I'm trying to remember. is this motor going in a Old outback with a 4EAT?
If so, Cancel the order on the JDM 2L. NOW!
That motor would only be good in an old mid Nineties Impreza with a stick.
That's my WELL CONSIDERED advice, since you don't have anyone really HELPING you here, just a bunch of
time -wasting Jibber Jabber.

When it is separate sump, it is easier to design specific oil for that purpose. When it is #hared sump, there is quite a challenge to provide shear stable oil and not causing LSPI with reduced SAPS formula.
Not sure about him claiming that the oil in the pump just keeps going "round-and-round" in the pump if it's in pressure relief. Typically, PD oil pumps will direct excess oil back to the sump when the pressure relief valve opens, but maybe Subaru oil pumps are different - ??
From what I saw on the video, it seems it gets pumped into one of the heads and not the other one and that would make it interesting indeed!
The EJ20 was sold in vehicles here, why not look at a 2004 impreza or something that would have come with the EJ20 and see what it was recommended

If the engine can manage the same speed in the same gear then yes. If the transmission decides to shift down because you push the acellerator further, then no it will likely be worse.
You can recirculate back to the intake of the pump.
He got WAY too much credit here. A Dental Surgeon is NOT an engineer.
Plus if you are dealing with a supercar with a large dry sump, that is a WHOLE 'nuther ball of wax than what most all of us drive.
