      I have an 88 . It has an ABA block and 1.8 head (uh I think). I need to know what distributor to get . It currently is non running but has a distributor from the 97-99 Jetta/Golf . All done by PO . I want to go the route of adding the knock sensor , wiring , knock box . But not sure what distributor and what years of things to buy . Searched and read for couple days .

      You need the 88 distributor. Techtonics has an adapter ring 503 843 2700

      Knock sensor uses a special bolt and very light torque 18 ft lbs??

      The 88 has a vacuum on it doesn't it ? I don't need that if I'm using the knock sensor setup. At least that's how it reads to me .

      Also , do you know where the stock location is for the knock sensor on an ABA block ?

      Thanks for the help

      Not, GX engines had vacuum advance Digifant PF and RV did not.

      You can use the distributor shaft with 4 window trigger from your Digifant distributor, place that into an ABA distributor.

      This is an easy swap, just knock out the roll pin with a pin punch. Take pics or notes of the orientation of the parts that come off and in which order.

      Place the 4 window trigger/ shaft into the ABA distributor, and use the ABA gear, then install a new roll pin.


      If your ABA distributor has two metal pins at the base, you can remove them by pulling the pins out or cutting them off with nippers.
      This allows you to rotate the distributor to time it correctly. On the ABA the pins were used to prevent the distributor from rotating because the ABA distributor single window trigger is used as a CAM position sensor.
      Requiredfor timing correlation on ABA. None of that matters on your Digifant, different system.


      If you need visual aides, search online using lots of keywords. The information is there, but the pics may no longer be hosted as this forum is 21 years old.

      Best of luck!
