Most evos in Europe use it on built engines and track focused evos.

Total or Liquimoly? Ive been researching on my end.

Not sure what would be preferred in the US, but I use Fully Synthetic Triple Ester Nanodrive Low Friction Technology Formulation. Millers CFS.

Never had a problem. In the Evo, temps are much lower and I'm using a better oil, which I replace every 2 events. That's why I'm not too worried about 240F oil temps, though I think I probably would have higher temps if I ran the car in 100F ambient temps and redline shifted it every lap, which I avoid. I am planning to do Blackstone analysis this year as well to make sure things are healthy.

I have not. Wouldn't engine clearances need to be tailored to the thicker 60 weight? My engine builder recommends 50 weight, so I think I'll stick with the thinner stuff.

I wish we could get Millers here easily.

That is a whole mess of adverbs and adjectives. Here in 'MERICA we don't buy nothin' with a name longer than two syllables.

It's a description.

Your setup looks good to me. I've always run 24-25psi for track tunes. I've used everything from stock turbo and O2 housing, to aftermarket O2 + FP Green. Pump gas, e85, you name it.
my oil gets WAY hotter than yours before I take a cool down lap (Rotella T6 before, 50w VR1 with FP turbo) . Stock oil cooler and radiator (with Evans, as opposed to water).
No problems. You should be fine.
edit: 340whp on stock turbo, 450Whp ever since.

I finally pulled the ebay O2 housing off, without removing the turbo (yay nickel antiseize used in previous installation), and ported out the passage for wastegate flow. It wasn’t that small, but I mostly removed the internal wall in the housing. Took care of the creep issue.

By "wall" you mean the separator between the WGA and turbine portions?

those sheet metal o2 housing dont last very long for heavy track use. i've seen many cracked on track. get a cast stainless one, usually dont have divided ports, so you wont have that boost creep also.
