Looks like ur heart is set on a swap. Don't be enticed by FB pages with swapped shiny cars, a swap where the owner is not very technically sound, turns out to be a disaster. These early PKDM cultus' are work horses, do not ruin your car. It's like killing a bee with a bullet. Get the issues fixed, get the compressor checked by someone that's not a monkey, get the timing checked, put new plugs and get your carb serviced by a specialist. You will regret a swap. It's not just throwing in an engine and then enjoy 20kmpl of fuel average and tire smoking acceleration, on the internet it's easy, in the real world, it's a pain in the @55 to even get the motor to work.
