Tracy modifies his EC2 to drive the LS1 coils as they can not apparently be driven by the same program that drives the stock Mazda coils. You end up needing one more wire as you now have 4 coils to trigger. So there could be an incompatibility problem with the car's stock ECU. I intend to mount my on a section of "T" aluminum, in two pairs, one coil on each side of the leg of the "T" at two positions. Then I will bolt the "T" to the firewall using a couple of the bolts now holding on the stock coils. They will give quite a bit more room between the rear (front) of the engine and my firewall.

Any downside? How are these new coils mounted to car or airplane? Jim Brewer Here is a side by side comparison with all 4 LS1 coils occupying less space (and weight) than the Mazda Trailing unit alone, not even counting the smaller but still big leading ignition module I weighed the two Mazda coils and together they come out around 9 lbs.
