Waste Spark Coils

[James Ballenger]

The coils are  GM #

1103608;1103646;1103745;10468391;10472401;10477602;10495121;1049771

App -> Buick 97-86; Caddy 98-93, 88-87; Chevy 98-87 (These were all I wrote
down even though other
GM brands were represented, also the book I had did not list specific
models, I suspect because these were carried on too many models to mention

There are multiple styles of the GM two post coils and these numbers only
represent one style.  Though can look up the #'s for the other two styles if
some people want me to.

Mitsubishi (turbo Galant & eclipse), Porsche, and Rx-7 coils are all very
good, but they are MUCH more expensive and not any better than the GM
versions IMO.

GM now has a new setup they will probably be running on most cars to replace
the old two post coils.  They are the coil per plug with the ignitor built
into them, but they are $40 or so each and not any more powerful than the
waste spark coils and they require a sequential ecu setup.

James,

I am interested in the part numbers & applications.  if you guys know the
applications i would be most appreciative.  my parts guy is good about
looking up
stuff via application but his cross reverence leaves much to be desired.

On a similar subject, Jurgen said 2nd gen RX7 but I am not Mazda literate so
i don't know my first Gen from my fourth gen.  on the subject of the RX7
coils, saying that they have that they have the ignitor in them, does that
mean that they are fired with a TTL level input?  if so that would kill two
birds with one stone for me.

thanks gents.
Bob Wooten

I used to use stock honda coils for the 600cc F4/F3 setup being run here
and they were pretty weak... you could barely even see or hear the spark.  I
recently just went with some GM $20 coils and good lord!  You could tig weld
with these things if you threw some argon in.  We rev up to ~13000 so they
should work fine for your app, be extremely cheap and just about the
cheapest ones you can get on the market AFAIK.

If anyone is interested in the specific ones I am using, I am some GM part
#'s what GM cars they correspond to and advance auto part #'s.

Have fun,
James Ballenger
