alot of them (and sh foresters) had bearing issues. i think the story goes that excessive swarf was left in the engine during manufacturing. but its possibly a bad batch of bearings or some other similar issue.

As far as I can remember, the bearing issue was related to Subaru reducing the amount of lead in the bearing material (environmental) and subsequently copper became deposited. In affected cars, there was evidence of copper in the sump oil as well.
Beernuts should have the full story as I think his MY08 was one of the cars with the issue.
And yes, it was first discovered on Foresters....

If the crank is phase drilled with more big end oil galleries yes ,if not no

I think I remember hearing of a similar bearing issue with the compound used by ACL too back then.

The crank oiling should all be good now. ACL race bearings will hopefully solve the Subaru bearing issue. I did lots of cleaning and changed oil twice before 500kms.

I am on v5 tune now as I gradually wind in some power after the run in kms.

After solving some vacuum leaks upon first start up which were caused by the o ring setup in the zero sport TGV deletes and changing spark plugs the idle has been nice and steady.

We are now bringing boost up and are at approx 14psi now but wastegate duty cycle is around 60% which is higher than preferred.

I checked the actuator rod to make sure the gate is closing fully and preloaded it lightly. Probably only one complete turn from closed.

How much do people run in preload or should I run nominal preload and move to a stiffer spring?

What ur current qastegayye pressure?

Pretty sure the spring that I started with is a 12 psi. End target boost is approx 22-24 psi.

i reckon you could go up to a 15psi actuator no worries. The closer the actuator is too your target, tue less you have to bleed off it. But has the downside of not being able to go lower should you want to.

I use the blouch upgrade actuator which has a 20psi actuator. It used to sit about 19/20 psi gate pressure on the td05. with the dom its upto about 22psi. I think the dom wastegate is maybe too small and causing a bit of boost creep. A turbo that size is probably starting to want an external gate.

Definitely need a stiffer spring.
