I think my spark system is on the way out the spark looks weak even though it all specks out when testing the ohms i suspect in the high end laod situations i am not carrying enough jiuce to ignite my fuel mix. So lets have it MS gurus have you heard of using other stuff to get the job done?
GM hei comversion is looking very complicated with solder here there etc as well so maybe an easy way to do that would be the ticket. I am realy at a loss here guys.

i think some guys are using coils from a neon or something.. havent really looked into it, but u better stay stock, cus ive already wired and built your MS for stock...

Ok but i might need to do the hei mod then seriusly my spark is sucking. I dont think i am over or under fueling it to much just that it isn't all burning right. I might try some bike coils with a new ignitor. I tried bike coils before and they did fine NA but once i was in boost they sucked, you think maybe i blew the ignitor when i did this?

I'm actually installing neon's coil, no.420A, from a twin cam engine.

These coil are huge and sparks like hell. I don't know your setup, but if you have 2 ignitor, you can connect the ground spark direct to the coil.

Very easy to install, almost bolt on:
-get a used or brand new coil
-get also its connecter (3 wires)
-the middle on is 12V, hack it from 12V ignition of the disty
-the left sparks cyl no.1-3, right wire 2-4.

In my setup, I've built a direct drive system, I have no ignitor, so megasquirt's firing the coils via 2 high current transistors VB921.

Stay away from HEI module, it's old and weak technology
