Headers and up-pipe.
All OEM rubber hoses on turbo side
I'd buy a Gates tbelt instead of OEM (my two cents)
New oil cooler, my builder wouldn't warranty motor without one.
Make sure plugs are 1 step colder for that projected HP.
New oil feed line kit, removing filter in banjo bolt.

Oh and a new PCV VALVE, Those are a pain in the rear to replace while in car.

The dom is perfect for his application. it'll make is 26psi of boost by 3800rpm on e85 no problems. Mine did. Going down the rotated rabbit hole for a DD is rough.

OP that should be a great DD setup.

Interesting thought on the oil cooler. Necessary if I am not going to track it? What's the benefit of gates over OEM?

I've heard of radiator shops flushing the oil cooler. But think of this, you may introduce some foreign material into your new short block. Peace of mind is worth $289.
If your going to track it, I'd research it further as you may need something bigger/better than stock. I don't know as I don't track my car.

Gates has a long history of quality parts. They are less likely to have a timing belt failure than an OEM unit. Just by holding an OEM and a Gates you'll feel the difference.

You can get a Gates timing belt for a fraction of the Subaru OEM belt at the dealership.

Everything looks good except I would go with a Fluidampr pulley and a different clutch
setup. There is a long debate about LW pulley versus a harmonic balancer on here - you can feel free to do more research on that topic. Instead of Competition clutch stage 3, go with a ACT HDSS. It has a full sprung clutch disc that can handle more torque, feels slightly stiffer than stock and does not grab like an on/off switch.

I'd like to see you actually prove this statement.

I'm not saying that the Gates is a bad belt, but stating the Gates is a better belt than OEM is a tall story.

It has nothing to do with whether or not you track the car. Smart people don't re-use the old oil cooler because you don't know what itty bitty pieces are lying in wait to destroy your expensive engine.

An new OEM oil cooler is cheap insurance.
Flushing out the cooler is no guarantee of removing everything that doesn't belong there.

Same thing goes for flushing out the oil ports in the heads. Flushing only gets so much. You have to go in there with brushes to get everything.

Do some research in the forum and you will see what I mean.
