i hope u find this info out.  I knwo the b15 were running corvette LS1 coilpacks, dunno what kinda modification is required but honestly, from everything i read/hear, our ignition systems are top notch and dont need much more.

some companies don't even have the correct plug size for our vehicles.  they keep just copying over the specs from the 02-06 models as what we have.  out diameter is smaller.  It went from 3/8" to 5/16" or 14mm or something like that.  I'm not even sure if the gap size is the same on the plugs.  What I'm getting at is that considering our plugs have changed, there's a good possibility the coilpacks have changed as well and what they fit.  I was told that all newer nissans like ours and the z have the new size plugs.  So possibly if there is the same mod for the 07+ Z and it fits, then you might actually have something.  what exactly would this mod be and do?

sorry for the long wait, forgot to check this.  There might be a company that already makes a high powered Coil pack for us, we just need to do the research to see in the parts can be cross referenced.  Wether it will be worth it, i dont know, but for those that must have every part available, it might be worth it too them.
