what coils to buy

[iluv2moan]

im running an ems 8860 and having problems with blowing spark at high rpms. (feels like it just hits a rev limit but 600 rpm earlier then it should)

atm im running stock (15 year old 7m) coils so they will most likely be the cause.

whats the best coils to upgrade to without having to go cdi?
are ls1 coils the answer?

i think the ems ignitor is pretty shitty so the inbuit ignitor of the ls1 coils would be a bonus.

im aiming for about 500 rwhp or 25 psi boost if that makes any diff

I'd try the ls1's

*Although i have not used any at that boost level or power level

LS1.

Use a steel plug, no irridium or platinum plugs, space the leads apart so they dont contact anything metal or eachother, and get em away from the heat (heat = resistance, resistance = spark rather go elsewhere but to tip of plug at the end of line)
