Hi mate, looks to be an interesting build. will it be used for street/track use?
I had issues with big end failure on my ej257 and would strongly suggest some form of baffle plate for the sump or a baffled sump to reduce the chance of big end failure on hard cornering.... oil starvation was a killer on mine.
The big issue with Subaru rod bearings is oil temp. You need to watch it like hell, I don't allow it to go over 105 C, I aim over the next year to get it to run closer to 85 C. I don't have any experience with turbo just NA at 8,000 rpm and rod bearings.
Attached is a photo of the Sump of a NA Subaru engine, the brown you see on the inside of the sump is burn oil that has cooked from the exhaust going so close to the sump. The steel on that side of the sump got hot enough to burn the oil that touched it. So as I say oil temps and rod bearings are directly related.
Last point don't use over size bearings on Subaru's its bad news stick with standard.
I've got a bit of experience with Subarus, so can help you a little.
As I do with all my customers however, before you can talk about a build, you need to let us know about the purpose of your car, the desired power band, how high you want to rev it, how much power you want to make, what fuel you'll be running and anything else you can think you should mention about your goals.
Once you've done that, I can give you a better informed review of your mod list.
