How do you time a 1993 subaru impreza? - Impreza Subaru Cars & Trucks

Which series engine,all the 'ej' series dont have a distributor like the earlier engines,that you could set timing.Timing in the newer range are set by cambelt,computer and cam/crank sensors,and the knock sensor alters timing under load.I would need some more detail to why you want to time it?Is it idling poorly,or is it laboring or knocking under load?This model had a common fault with the knock sensor failing,which basically didnt allow the timing to vary enough when the engine was under load or accelerating.Hope this helps or supply some more detail and I can endeavour to help you.
