Has anyone tried to put MSD injection into their RX8?

Please explain?

Are you talking about MSD coils, ignition amplifier or some outdated msd fuel injection system?

OK had a chance to look and assuming you mean this http://www.msdfuelinjection.com/mefi4.html

Matt didnt you sell the 8?

yes and yes. I did sell the car but still stalk around the site from time to time. I saw a demonstration comparing the MSD ignition spark with standard ignition sparks (on a piston enigine) and it got me thinking if there would be any gains in power and,or efficiency if an MSD system was fitted to an RX8..

I know of a company that was founded on that EXACT premise.
