Great research on the subject. I suspected the flywheel was different. For a 4 amp increase, it sounds like a waste of time and $. I wonder why the original poster had regulator problems in the first place.
Now, if you could adapt a 23hp 20-50 amp system to the earlier blocks, that might help justify the cost. I think the engine block is different where the stator bolts on. Well, just buy a bare block for a couple hundred and put all the 18 hp parts on it with a set of intek 44 pistons for flat tops. Oh the 16 hp? crank, it would need a long rod and I don't know what piston, it would be like a 16 with a huge overbore. Oh, just buy the bigger crank for $150
On a more serious note, maybe see if the stator could be adapted to the earlier blocks. I have a small alternantor from a '70's datsun I would hang on some where. Otherwise, I'd live with the 16 amp system that's worked fiine for a decade. I guess it helps to have somewhat of a real battery size in the argo instead of a lawn and garden battery.
About the magnets in the flywheel, reminds me of the old GM alternators. The only difference in them was the size of the rotor windings (magnet). The stator, diodes, and regulator were all the same.
