torxxx Posted May 14, 2005 Share Posted May 14, 2005 The only differenece is the blue topped subaru coils are made to run WITHOUT the like ballast resistor that wires into the positive on the coil A coil is a coil. Almost any coil will work, it will just be higher/lower voltage then a stock subaru one. All the accel coil is that everyone uses is a coil for a standard V8 Chevy 350. puts out 45,000 volts instead of 36,000 like the stock subaru The roomates 85 Brat is running off a coil from a 88 SPFI wagon so any of them will work Link to comment Share on other sites More sharing options...
