Are any of you sprintex folks or other forced fed owners having spark issues? What coil/distributer setups are people using?

I presume external coil is the norm?

Cheers.

Havn't had any spark issues with the Sprintex and factory ignition system. Sprintex do recomend plugs 1 step cooler than he OE plugs.

AFAIK unless you are running quite high boost levels or there's a problem with OE ignition, you shouldn't need to worry about anything besides the plugs.

Already put NGK 7s in

Big boost - yes.

Ian,
you probably already know this, but for others following this thread that might not. In high boost/high compression situations, you can get spark supression. I have a mate that has an old rwd lancer with an astron motor in it with about 12:1 compression and i reckon that is what is causing his running problems.

Maybe the 380 coil pack or an aftermarket ignition system might be tho go mate?
