Time for another update...
Picked it up yesterday from the shop. I'm about 30 or 40 miles in to a 500-mile break-in period (no revving over 4,000 rpm in that time) and have an early oil change scheduled for 1,000 miles. Can't really get much of a feel for it until both of those are out of the way, but power is noticeably improved, there's far less downshifting on hills, and overall it's doing what it should be. Another few weeks and I can start looking into the next stage of upgrades.
Just did the 1,000-mile oil change day before yesterday. No noticeable oil consumption, it was surprisingly clean, and the coolant level looks good as well. Despite an initial drop of a couple of inches in the overflow reservoir, it held that level from about 200 miles onwards. Things look promising, but I think I need to move back to a slightly hotter spark plug; I'm currently using NGK BKR6E-11s, when stock specs call for a BKR5E-11. We'll see; the upstream oxygen sensor was also replaced at around the 700-mile mark, so I'm waiting for the computer to fully catch up before doing another set of plugs.
In other news, I've ordered the next stage of the lift. Going by
this thread on
offroadsubarus.com, I'm adding another inch-and-a-quarter of lift with body lift blocks. On top of the 35mm springs (which settled by about 5mm over 10,000 miles) this should net somewhere between 55-60mm of lift, or roughly 2.25". They'll get here next Thursday if UPS is to be believed, but it'll be a week or two before I have the time to put them in. Haven't fully decided if I'll move to SG struts at that time or not; finances get to dictate that one.
Related to this, I also ordered an additional six lift blocks to space down the rear trailing arms with as part of the package. It looks like this may be a workable solution to the rear wheel tuck issue; I certainly hope so, given that there's really nothing off-the-shelf for it right now.
Anyway, work progesses. Next goal after this is to score a rooftop tent for cheap.
