Started digging into things while replacing the stock radiator. Sometime in the cars history someone put a msd ignition in, but left the stock coils. What coils do you guys recommend I know msd gas their own. 87 T2 bnr stage 4 microtec ecu 720 primary 1680 secondary injectors.

 

What MSD ignition did they add? Was it a single 6A or digital 6A box on the leading coil? Multiple 6A boxes?

TBH im running a Digital 6A box on the leading only coil for hte last almost 10 years with no issue. The stock coils are quite strong and can handle increase dwell(if you wished) better than something like the stock LS coils. Granted if you can drive 4 independent coils(instead of batch fired leading) most newer coils could be a benefit.
