The flow of energy and the circulation of matter

The previous post gave a little teaser. The car is on its way - well, it’s pretty much here. The next port is ours. And since it had to cross both the Pacific and the Atlantic, not just the Atlantic alone, it’s high time to prepare the parts for the RHD/LHD conversion. You already know the donor: the GF, ever so slightly rolled over somewhere in the woods near Wrocław.

We're Arming Up

For now, just a teaser to whet your appetite. Tomek and I went near Wrocław to pick up this crunchy one:

It’ll be paired up with the STI (at least for a while):

Impreza's first “failure”

Just as I started to feel like, after nearly three years with the Impreza, I was finally getting used to car’s wild character and constant readiness for craziness - I found this surprise under the hood:

The throttle and intercooler air duct hose decided to give up. The split runs around one-third of the circumference, and it looks like boost air must have been escaping through it. I’m wondering if that’s what I was sensing - maybe it was just running lower boost pressure? In any case, the hose had to be replaced. I bought this one:

Latent Heat of Vaporization III

To be honest, I was convinced that by this time the latent heat of vaporization would be automatically released thanks to my hobby project. However, holidays have their own rules, and the whole thing has been slightly delayed. Nevertheless, some very minor progress has been made.

I replaced the original four-liter tank with the Spec-C version, which has a capacity of twelve liters; I also removed the stand on which the smaller one was mounted - seems like a simple thing, but there’s one nut hidden underneath, in a rather non-obvious spot.

90871FE040 - NLA?

Maybe the Impreza isn’t a classic? Or maybe it’s not a classic just yet? But for sure it’s slowly approaching the “NLA” status — no longer available for purchase. And that’s exactly the status I saw while looking for 90871FE040 a replacement reinforcement panel for the scoop. It doesn’t seem like a big deal, but it’s been giving me gray hairs for a long time every time I opened the hood. So I finally decided to go to war with this wee plate.

Latent Heat of Vaporization II.V

Almost there — just about ready to go. I’ve gathered all the missing parts. A local machinist came to the rescue and turned a custom adapter fitting, modeled after a T-joint, to make everything connect neatly. He’s an old-school kind of a guy — the type who can tell you the thread pitch in turns per inch without putting on his glasses and we mostly use metrics here.

The T-joint:

Oiled-Up Forester

For the record, I’m reporting that the Forester got a new dose of oil (Castrol Edge LL 5W30), plus the filters (air and oil); mileage: 332430 km.

And since I was already tinkering with it, I also fixed the wipers. The plastic bushings in the linkages were completely worn out, which resulted in the wipers mainly focusing on the A-pillar and the cowl panel. A simple fix, though a bit costly; I know that the plastic parts alone are available, but I didn’t manage to find them and with a holiday trip fast approaching I went for the whole set. You just need to unscrew the wiper arms and remove the cowl panel.

Dead pedal

This post could’ve been just one sentence: “I bought a great dead pedal — anyone who owns a GD STI should have it.” If it weren’t for one detail — or rather, another dead pedal I also bought. Let me explain.

I read somewhere that the dead pedal from the BRZ (part number 38010CA010) fits the Impreza, so I bought it. It looks like this:

As with all OEM parts, it’s well made, with a nicely formed aluminum plate mounted on a plastic base. But what caught my attention were the screws holding the aluminum — not the ones in the photo above, since I’ve already replaced those — but these:

Impreza, Impreza, Impreza, Forester, Impreza, Impreza, Impreza

That’s kind of what it looks like — but every now and then, the Forester gets some love too. That moment has finally come. First up: gauge cluster backlighting. I’ve done this twice already, and this time I said enough’s enough, time for LEDs.

The only complication was that, because of the boost gauge, I had to lower the entire steering column to get the cluster out.

One of the three main bulbs burned out, the one behind the rev-counter:
