Jim,

  Jim,   I am uncertain about using them on a car with the stock ECU.  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.

Ed,
Can I use these as a replacement on my '87 car without alteration?
Any downside?  How are these new coils mounted to car or airplane?

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.
