Ok so I’m losing power and I think it’s the cap and rotor.

    1993 Subaru sambar ks3 sc. I cannot find a cap or rotor for it anywhere. Does anyone have a part number for one that works. It sounds like a sports car with launch control at this point lol

    There are a few different versions depending on who made the base of the distributor. I have the part numbers for the Hitachi-made supercharged rotor and cap on my spreadsheet. Looks like there are three versions of the cap.

    I can say for sure that the rotor is the same for all of the supercharged vehicles between 1990-1998, and that is 22157KA080


    If you can tell me your VIN, I can look up your specific part.

    Looks like you use the same cap as me. 22162KA190

    Both 22157KA080 and 22162KA190 are still available from JapanParts. They should charge you about 2000 yen for the cap, and about 1000 yen for the rotor. I would suggest buying more than just these two (or possibly two of each?) to make the shipping worth while. Since JapanPost is not currently accepting airmail to the US because of Covid, the only options for shipping are Fedex/UPS/DHL right now.

    It gives a good starting point at the very least. I’ll dig through some stuff and see if I can cross it to anything somehow. This helps a lot!

    I can save you the time, as I have looked for the last 3 years for a cross and there isn't one. JapanParts will be your cheapest source.

    I also forgot to mention the cap O-ring which you will want to replace at the same time, that is 22171KA070 and is about 400 yen. The old one will have either hardened or stretched out.

    If you have a pick-a-part yard near you, you could take your old one with you, and check Subarus, Toyotas, and Nissans, and see if one matches. Then you could go to NAPA, and see if you can order, a new one.

    You might be able to take your old parts to a NAPA or other full service parts house that stocks parts for more than cars, and see if they can match it. If you can still read it the distributor data: manufacturer and model can help. Sometimes they can look that up, and go from there to find matching cap and rotors.

    The trick is to show up on a Wednesday, at about ten in the morning, when there is no one on the store, and they are bored, and have time to look through the shelves. If you try it on a Saturday, when they have lines four guys deep, they will give you the brush off.

    And, have you tried cleaning up your old parts? Take an Exacto knife, and scrape any corrosion off the contacts in the distributor cap. they are re typically aluminum, and you can sand them with a bit of wet or dry sand paper to get the corrosion off. Take a file or sand paper and clean the edge of the rotor, and the contact point, where the electrode form the coil lead rides on the copper. Blow the whole thing out/off with some brake cleaner and let it dry. Typically if your getting misfires from problems with the cap and rotor, it is because of internal arcing. Cleaning it up will generally eliminate that. If you’re in a high humidity climate, just condensation inside the cap, and get ionized, and cause arcing. that is why a lot of the caps had a lead to vacuum, to keep them evacuated.
