Part 2 of 2

My build is practical and structurally sound. Bolts in place with a single bolt (use red loctite). The connectors are heat shielded and modular as seen on ebay for $95. The bracket is not as refined as some others but you see the coils and wires not brackets. The plug wires are MSD 8.5 in red. The outfit will come complete ready to bolt in and connect up. You do not need to tune your RX8 to accept the coils. Coils have a 1 year warranty.

$349 for the LS7
$379 for the LS2

Part 1 of 2
You can search and compare LS2 (D585) commonly called the Yukon coils to LS7 (D514A) the Corvette Z06 coils. My conclusion was that any output above Mazda OEM was fine. The output of the OEM coils is not the problem, it is the limited life of such a critical part. They work when they work. The GM coils are high output (120 milliamps vs 40 milliamps for normal) and some of the rotar heads have offered butt dyno results. At the end of the day the GM last multiple years on dozens of applications. I originally wanted to install the LS7 on my car. A Z06 Corvette is more of a performance vehicle than a Yukon, but I was having a critical failure and had to act fast. So I went with the LS2. You find more LS2 installs in the RX8 forum and that is what BHR (http://blackhaloracing.com/?page_id=...&product_id=19) uses. You decide for yourself.

The cat is pending sale monday if he doesnt buy it I'll let you know.about the ls system are the D514 coils as strong and push the same amount of power?If I sell the cat I still might be interested in buying the ignition system from you.Does it come with everything ?
