Im tryin to figure whats the best ingtion setup that will support 500hp plus. I tryed running stock coils and a msd 6al and that worked till about 450hp but then had problems above that. Im running the aem ems with full fuel system and a mild street port and greddy t88h.

i don't know what the best setup is but i run the NEW Jacobs Rotary Pro Pak from ari yellen's rx7.com. ari co-designed the unit expressly for the rx7 and makes 700 rwhp. according to him ignition is now not an issue. the old jacobs had a problem that has been addressed. you might call them and check it out.
BTW, who are you and where are you in my state... are you going to the RR?

I talked with ari about the jacobs system and he couldn't gauranty that it would work or not for my setup

...and I was running on trailings only. I'm fed up with the Jacobs. I had it set up to fire two separate V8 Crane LX91 coils vs. the stock dual output lead coil. I ran good for a year on it. Maybe the amp is not able to deal with firing two separate coils (ea. acting as a lead coil)?
