Coil to improve spark
 

I want to improve the coil on my 911T 1970 carb engine. I have looked at Summit Racing SUM-G5220 or Jacobs energy coil 530 or Proform Parts 66958C. Comments please

Try MSD 8200 series coils....the 8202 @ $45 is good...or you can get the chrome one.
They put out about 45K volts .... I used one in my 69S ... cheaper than the Porsche part....no leaking...ran fine.

no improvement over factory.
if you are having issues, i would look at where the problem is, and not cover it up.

the MSD is good stuff, but porsche did a really great job on the ignition. you need a race motor before you start to need more ignition, even then its ??

coils are just a multiplier. they are usually 100:1

All Thanks
