With a blower I used Autolite 3923's gapped at .030, MSD 8.5MM 94-95 Specific plug wires, MSD blaster coil, MSD6BTM (box and boost retard) with the stock Motorcraft cap and rotor.
I use Performance Distributors ignition kit...it comes with their Livewires/Dynamod TFI/Screamin Demon coil/Cap&Rotor... I use NGKs V grooves gapped to .060
Im NA, but its a sweet system and have had not a lick of trouble with it...I was looking to replace it all in one shot...
msd cap and rotor... get a good quality of you may get interference, i did with a grey cheapie and my radar detector went nutso.
I got a descent set of wires, but definatly get a good set, no 100 dollars or anything, but some good 8mm or better. check the impendance. I went with cheap plugs too. However....
I plan on upgrading when i get the turbo on the street.
Performance distributors wire and Dyno mod( these are both very nice ) I was tired of burning FMS plug wires. For boosted applications, I hear iridiums are the best? I use Crane ign box and coil.
MSD cap
MSD rotor
MSD 6al
FMS 9mm red wires
NGK Tr6 plugs gapped at .035
stock TFI, and coil...the coil will be replaced with a MSD coil before it comes back out of the garage this winter though. TFS...I may replace it with a stock replac. unit.
