and some people enjoy the challenge looking for bits, and hey, the reward can be a car you rebuild can deliver 300 to 800,000km on that build if maintained. And survivability can depend on your intended usage too. If only postage to US was affordable (reciprocal even ! )- I have a hoard of EA81 heads and oil pumps spare valves, even have a few sets of pistons OS
I agree with everyone the EJ is a more advanced engine, more power, more parts, more lard, probably more reliable and fuel efficient and if you can make one fit and work - even more rewarding.
It is always going to be a case of do what you want, assess the info offered. I used to hate the EA82, love the EA81, but other way now and as it sits I have an EJ20 and its AWD 5MT sitting in a Brumby waiting for more motivation and investigation. The AWD 5MT from a 2.0 litre Impreza fits the trans tunnel better than EA82 five speed. The EJ looks like it belongs there. Plenty of EA81 bits in Oz for export except new oil pumps
