They will do the job, however it will not allow the dis 2 operate to its max potential. Not doing the coils is having half the performance taken away. Plus they are the cheaper part

so I guess it would be better to do the coil packs first then do the dis-2 box
i would agree on that one.

agreed with turbo tech...
the msd coils with the dis 2 will help it transfer and more efficiently. msd;s max output is 40,000 volts which is what the coils are rated at.
most stock ignitions though will not even be in that range...
as even said, upgrading your coils is uselss without upgrading your ignotion. It's kinda like puttin on an exhaust but not an intake, sure you can let more out, but ur not gettin n e thing more in. U need to upgrade your ignition to allow more current TO the coils, which then the steped up coils send that enhanced power to the plugs...
i have one ?, if u get the blaster coils and such, how does it get connected? does your connector from your IDI cover connect right to them/it?
The stock coils and ignition are good enough for any car on the org. Anything else is just a waste of money. I work at a shop and we build high performance Chevy enigines. We use the stock coils on out 450hp 2.2 turbo Eco and yesterday Saturn Motor Sports dropped off an Eco that they owed my boss. 500 hp, revs up to 10,500RPM with the stock coils no problem.
sure you CAN but why would you when the stock is inferior, just cause it has 500hp dont mean its efficient or cant be better

that didnt answer what i asked. I was asking about puttin in MSD coils. and running plug wires
if i get coils, and run plug wire, what plugs into the coils to get their juice?

its VERY obvious, no matter what your shop works on, that you havent tried an MSD ignition setup.
just cause something works FINE/OK, doesnt mean it cant be improved....
msd is well worth the money, if you can afford it.
its like saying...sure you can wear off the rack clothes that fit, but custom tailored clothes fit way better, prob ARE more comfy, and will last ALOT longer.
and chances are, if its really 450-500HP cars something was manipulated with air fuel and spark in the computer area....

I'm calling BS on your 10,500 RPM 500 hp ecotec. Especially on entirely stock ignition.
I was a retard, and now I'm permanently banned.
I didnt say that the engine was stock now did I? I said it has stock coils. The engine is fully built. Im not F'ing stupid, I would never say 500hp and 10,500rpm's stock. Yes I'm sure the MSD coils are better but if we can make 450-500 hp using the stock coils, then I'm sure most people arnt going to see any real performance gain from these.

some of the statements you made above make absolutely no sense above though...
stock coils... its a fact once you up the voltage passing through, they will burn out sooner.... like anything else logical car wise, the more power you add the quicker things wear out.
so if those cars are putting out that much power, spark, fuel and air has been increased.
meaning the coil packs WILL wear out faster than on a reg car.
however on any car, upgrading a coil pack to which will last longer, has less resistance meaning more spark will get through although minimal on stock ignition.....
not a waste of money, more or less money well spent...
also if you read, the original poster is adding an msd dis 2..... pretty much it would be beneficial to replace the coils....
although not needed, you do gain efficiency rather than overworking stock coils...
this should go without having to be said, but not every gain in performance is about more power...
thats what alot of people here miss out on..... LONGEVITY and EFFICIENCY make sure you get your power gains for longer periods of time.
its obvious that whoever built the two cars your speak of if they dropped that much money in there, they have the money to change coil packs often. also how long do they run their cars? track only? or is a daily driver where its gonna see constant use like the majority of people here.... this is where LONGEVITY shows.
for someone who isnt really on a race team, upgrading to a stronger and more efficient coil pack ISNT a waste of money.
this BS of, "well this engine uses a stock --fill in blank--- so this is fine for everyone" doesnt fly.

That is one possible role for a capacitor, but they can do many more things depending on how they're used. The capacitive discharge that MSD uses is exactly that: a discharge.
The following is informational only, for liability reasons, I don't recommend you actually discharge capacitors or inductors:
If you want to see this in action, you could take a small capacitor (DO NOT use an audio one), charge it across a 9V battery, then touch the leads together. You get a nice big spark. In a similar manner, if you charge a small coil across a 9V, when you remove one of the leads, you get a spark. The bigger the coil (in mH), the more power it takes to charge, but the bigger the spark will be. (I watched a class-mate in first year electronics shock the crap out of himself to illustrate that this actually works)
Since we have a limited amount of time to charge the coils while the engine is running, and the bigger coils will take longer to charge, we want to charge them with a higher voltage. The MSD steps up the voltage using capacitive discharge, so the coils will charge faster and more fully.
I won't bore anyone with charge / discharge curves of capacitors and inductors (coils), but if you want you can find info in any entry level electronics text book.
look at what the GM race teams are using and also any car in the Nopi Race series or NHRA, they are using the msd digital 7 with the distributor add on, nobody with any serious power uses the stock ignition, sure it might be fine for 5-6psi but pretty much anything after your just giving up power

can n e one answer my question?
The coils would just plug in like stock to your leads.
sorry, on the TC motor it will not work with the idi cover. You would have to use wire leads, and some plug wires to go to the spark plugs. (Sorry I was thinking of my motor instead)

are you sure about that? or just talking without knowing
http://www.ny-jbodies.org/library/engine/2.4/msd2/msd_dis.asp
that link just tells you how to use the dis2 box with the stock coil packs the whole thing this topic is about using the blaster coils along with the dis2 box
my bad... i read it wrong....
thought he was referring to the msd dis 2 NOT work with the idi cover....
didnt read it initially as the coil packs not working with the cover.
my bad.
for doing the conversion, contact a guy (look him up) named jetblackgt....
NO, i want to know how to put in MSD blster coils in with stock ignition until i can get MSD ignition, i know i need to get plug wire, but how do i wire in the coils from my ignition module in my IDI cover??
