--E6K&(3)MSD's or E6K&JacobsRPak?--
Here's the scenario, what is the advatage of hooking up 3 MSD 6A's to your FD? I know 1 per coil and there are 3 stock coils.
But why then does the rx7.com team stress that the only important key in ignition performance is to amplify both the leadings with their Jacobs Rotary Pak. (just the leadings)
They also claim having the trailing fail, but because of the Jacobs on their leading, they still ran fine with over 500rwhp. Heads up on this question please...

Take anything from RX7.COM with a grain of salt - they are trying to sell and push their products.  Take anything from anyone who tries to push Jacobs products with a grain of salt - their advertising is rather overstated...

They claim that the Jacobs Rotary Pak has the highest amplification out there, more than the MSD's. That the rotary engine requires the most out of any other engine, as far as spark. You have to think about their proven performance. If it works on their vehicles, then shouldn't it work for everybody else? The 3 msd set up are usually on straight up drag cars. Not to knock on the people that run that set up. But rx7.com are close to stock. Don' you guys think their method is worth following?

The stock RX-7 coils are pretty good.
If I had to do it all over again, I would have spent the $300 for some type of other mod.
To be honest with you, it doesn't noticably improve performance.

i'll agree with Ted, they seem to eager to promote thier sponsors products, instead of the best product. they say thier car runs a T78 kit, so they sell more of those. if they told everybody it was a T88, everyone would buy those and then complain when thier cars ran like slugs.
If MSD was willing to sponsor them, you had better believe that they would be running MSD ignition in that car; that is of course, if they dont already have a MSD 6A inside that blue jacobs case

I don't think that is why they put that up there is it?
they put it because of the arguments the aussies have been getting in with RICE RACING, particularly that latest post by Fried_Rice about RICE RACING.
the post was deleted, but the argument continued here:

in my experience with the stock and MSD ignitions is that there is no need for the MSD ignition parts on most applications(as well as any of the other imitators). I have run up to 12psi of boost and have never had any problem with the stock ignition. I have also used the MSD parts and have had no problems, but I did not gain anything with the MSD parts. Dyno shop that tuned my first Haltech install insisted I use an MSD digital ignition box and only after I agreed to not hold him responsible did he try the stock parts. he was very surprised and found the stock parts worked perfect. he had always just tossed this stuff as a general rule. I would use the stock ignition until it starts to give you problems. If you are using a giant turbo and intercooler and running massive amounts of boost then an upgrade of the ignition will be needed, but otherwise you will be surprised by how well the stock setup works and the money can be spent elsewhere.
