Nice write up. Love that color and wish I had found one before the blue one I bought.
3 notes and a question:
I need to try your method of mounting the ambient temp sensor. I put mine as far from the oil cooler as I could and it reads wicked high. Outdoor temps 80 to 120 no matter what on the dash now. Can’t use my auto temp interior climate control because of it. Maybe it needs to be in direct airflow or something.
I’ve found the EJ motors oil filters for the current gen STI bolt up nicely (M1-108a, Mobil 1 filter see photo). Not sure if it’s better sized than the one you mention above (I think it’s smaller than the Greddy) but it is much easier to find at your local store than special ordering the Greddy filter and will be around longer than any 90’s era motor part.
For shits and giggles I installed this sandwich adapter plate on TOP of my Forester XT oil cooler sandwich plate to see if it would work (see photo, it adds about 2.25 inches in height). It baaarely clears my hood and the hoses make contact with the high pressure A/C line AND I had to put aside the oil sensor port adapter for the left/front hose. It was just too tall, but I’m told there’s a way to get oil temp and pressure elsewhere so I left it out entirely. I put some electrical wire wraps around the part of the oil cooler lines that makes contact with the A/C line so it wouldn’t rub on the woven material (see photo). The tops of the lines leave the slightest of indents in my hood insulation (BRZ not FRS), so I kept it. Best of both types? Either way, currently running both oil coolers, 8 or so track days no leaks no issues.
...Have yet to figure out how to properly drain the cooler of oil during an oil change. Just using the normal drain plug, and replacing the same amount of oil as before despite the extra capacity afforded by the cooler. I don’t want to try having the car on but engine not running (I assume this means the oil pump is running) for fear of running the oil pump dry/losing prime. Any advice?
