Re: ED engine update...
EL engine is a better candidate than an EF - the EF uses coil pack ignition whereas the EL uses dizzy just like the ED. This has significance because if you use the EF engine you'll have to swap over the dizzy and coil from your ED - and I'm not actually sure if the ED dizzy is in fact a straight bolt in on the EF (as it'd be replacing the cam phase sensor which is what's in the dizzy location on an EF) - plus, the EL rocker cover will have the correct clips etc. for plug leads from a dizzy whereas the EF has a completely different lead layout to the dizzy setup of ED and EL.
The timing covers on both EF and EL will be different to ED - but this is only significant with regard to the timing mark (I think the EF and EL just have a TDC mark - not the 10degree mark as well like the ED) - but you could probably work around that buy making your own reference mark from measurements off the ED cover.
Also keep in mind that for both the EF and EL the belt setup on front of the engine is different to ED so you'll need to use the complete EF or EL engine (ie. including it's own alternator, power steering pump, water pump and aircon compressor with serpentine belt setup) - or do conversion / hybridisation work to get it all to operate the way the original ED setup does.
If you don't swap over / convert the ED alternator, water pump, power steer pump and aircon compressor and stick with the EF / EL serpentine single belt setup then you'll also have to replaceace the std ED radiator shroud with an EF or EL fan unit - and then of course have the wiring setup to run those fans.
Also, if you leave the BBM on the new engine (ie. rather than swap over the ED manifold) then you'll need to lengthen some wiring and fit the EF or EL airbox and ducting - and also the ED ECU of course won't drive the BBM so you'll need to run it on either long or short runners permanently or fit up an rpm switch setup or fit an EL ECU and run the wiring etc. for it to operate the BBM.
IT'LL GO OR IT'LL BLOW!!!
