Looking to get a new coil for the van, but, in future (hopefully the very near) I am going to upgrade to a 123 distributor. Looking around at all the specs of coils I cant work out what I need, for a 123 I've been told "You can use any coil you like : stock or high energy : but the primary side of the coil can NOT be below 1 Ohm". Looking just at the flamethrowers there seem to be a number of different option, ranging from 28,000 volts to 60,000 volts with a resistance of 0.6, 1.5 or 3 ohms. But what does that all mean in real terms? I was going to have a look at a few manufacturers but couldnt work out the best one from one to compare to another. As I understand it, the higher the voltage the bigger the gap you can have on the spark plug, but again, what does that mean? A standard Bosch Blue looks to run at about 3.3 ohms. Anyone running a similar system, what have you got? Cheers Stu
A standard Brazilian "blue" Bosch coil will work fine with the 123. Buy a new one - only about £18. You don't need anything fancier.
Whats the differnece between this blue bosch http://www.vwheritage.com/vw_act_shop.product_pID_212017_lang_EN_country_GB.htm and this blue bosch http://www.justkampers.com/shop/ignition-coil-12-volt-j11507.html Cheers
