I have a FB that I am putting a 89-91 13BT into. I know I have to at least upgrade to the TII leading and trailing coils, but I guess my question is... is there a good reliable ignition upgrade, that works well? Has anyone any experience with MSD 6A? what other makers of ignitions are good?

i have the jacob's rotarymaster. its a good unit. i have read though there are equal systems for cheaper. now they have the propak which is stronger. i know the jacobs are tuff units though. very simple to hook up. i noticed better throttle response. a little more power on the high end.

i have read you dont even need an ignition though! unless you have a high hp engine. if i were you i would leave it with the stock ign. from a TII and see how it performs. aftermarket ignition isnt all its cracked up to be. not alot of power from it. but its a good mod if you can spare the cash.
