Improving ignition

[Bax]

Hey guys. I was thinking of upgrading the ignition system of the gtr motor.
Over 1.2 bar I get misfires even if the a/f ratio is at 11.5 or sth.I used to have bkr6eix and then upgraded to ngk bkr7evx plugs which helped a bit but I'd like to know what spark plug wires I should get and if I should get an MSD Blaster SS coil or Blaster Coil 2 (which one is appropriate?).
Also with the spark plug wires do I take the 5th one that goes to the coil or I have to buy one separately? I've read in another topic that with an upgraded coil this lead that goes to the disty gets fried.
Also fitting an MSD 6A will be of any use?

NGK, or Magnacore. No more than .030, .025 is better. I have an old school HKS coil that Corksport found for me, and I use a msd blaster on the rallycar.
