Dang ok Thanx for the other info tho. I ran a MSD blaster 2 coil on my JDM 93' Honda Prelude & it ran cleaner & helped free up/restore a lil power were it'd been lost & 1-2 that wasn't tapped yet. But idk if I ran a ohms resister on it be use I didn't do the install with it being JDM & other reasons. If anyone runs MSD ignition coils without a ignition timer please let me know ur set-up on ur XJ.
