I have 240Z with modified L28 and 280ZX ignition and coil.I was wondering if swap from stock 280ZX coil to MSD will benefit my car.Also when i was looking i found two MSD Blaster 2 coil one is # 8203 includes coil,coil boot,terminal & a ballast resistor for use on stock type vehicles as well as ones equiped with MSD ignition system,and the other one # 8202 for MSD ignitions.So i suggest i need first one,right? Do i need to use ballast resistor with that coil? Thanks in advance.
