I am considering buying an '87 DX with the standard engine. I wanted to put a later HF engine in (the D15B6) but after reading about pressurized fuel systems, I got scared off. I will stick with the carburetor, I suppose... welcome to 1925! Should there be any problem swapping a 1.5L D15A2 (the DX engine) for a 1.3L D15A2 (the HF engine)? I am going for high mileage which seems to be the reverse of what everyone else is attempting. I don't want to have new motor mountpoints welded in and I don't want to have to reroute fuel lines or AC lines or any of that. There's lots of specific talk about specific details in these forums, but little talk about the big picture things like... where do you get an engine? Can you even get 1.3L D15A2's? How does an engine arrive? What about the tranny, I'll have to get the HF tranny to boot. Am I digging myself a hole with this swap?
