Where are ya'll getting your filters from (air, oil, etc.)? I'm not gonna order NOS parts from Japan. Just lookin' for reasonable replacements. Also, peeps with supercharged Sambars: What octane gas is working best for you? Thanx!
I've gotten supplies like that from mini4x4.ca at reasonable prices before. I've gotten a Gates timing belt from Amazon which was well made but it still was 80 bucks.
Air and Oil filters you should be able to get locally. Take a peek at @rkrenicki 's parts list and you'll see a bunch of cross-reference numbers for that kinda stuff. I'm still trying to sort out how I can get distributor caps (and rotors) too without having to ship them from Japan.
The oil filter is the same as the Subaru Justy, so anything that fits that model will work. You can even buy the original OEM filter at any Subaru dealer if you are so inclined. Air filter is the same as some older ford, I do not recall the model off the top of my head, but it is on the spreadsheet in the references section. I personally use US Premium (93AKI) which is fairly close to the 90RON fuel that is used in Japan. It also tends to have less/no ethanol depending on the station/brand that you use.
