Are you sure the second one you have is a nippon?
Also, with EA81s at least, the Nippon and Hitachi dizzies have the same specs. Same curve, same spark, etc. You wouldn't notice one lick of difference between the two as far as performance.

As far as Advance curves there is actually a bit of difference. Both have very similar mechanical advance curves, totaling up to 15 degrees of advance at 3000 rpm. The Denso disty can only add an additional 8-10 degrees with vaccuum where as the hitachi can add more than 15. The denso disty is also meant to be used with the feedback carb system. If you don't have a feedback carb, I would stick with the hitachi.
I personally think the quality of Hitachi components is way higher than Denso. Plus the Hitachi distys are somewhat serviceable. You can easily replace the mech adv. springs or adjust the air gap. Densos are all but a sealed, non serviceable unit.

Thank you all for your feed back, you all have helped me make up my mind. I will stick with the Hitachi anf just rebuild it, well you know what I mean. The only other ? I have, is can I still use the Accel Super Stock Coil: Primary Resist 1.2 Ohms Secondary 8.9 K Ohms; Turn Ratio 100:1; Max Voltage 42000v wwiith the Hitachi disty?
I can tell you that the resistance values are very close to stock specs.
Primary=between 8-1.02 ohms
Secondary=between 8-12K ohms
But I have no experience using one.

I was thinking of runing an Accel Super Stock Coil: Primary Resist 1.2 Ohms Secondary 8.9 K Ohms; Turn Ratio 100:1; Max Voltage 42000v; Yellow.
Do not waste your money on that hunk of garbage. I just had one of them go bad on me this weekend. All of a sudden my car died without warning on the highway. Tried to start it and it would crank but the tach wouldnt move. I put the original coil back in and all was well. I would say stick with factory coil as these engines really dont put out enough power to warrent getting an aftermarket coil. I never noticed a difference. If you really must have an aftermarket coil go with a MSD. Ive heard nothing bad about there coils but have heard tones bad about accel. Do a search on this board for Accel coils and you will see the horror stories that other board members have told. I just added to it.

I have one that came with my brat, and I never noticed ANY power difference from the stock coil.
