On the 2.2 Ecotec, I see some went with the DIS-2 and either MSD or Accel coil packs.
I am wondering this though, could I do this incrementally?
In other words, could I buy two coil packs and have them installed and get the MSD DIS-2 box later?

Thanks!


My wife's 2003 Ecotec 2.2 liter Sunfire:
* 2 1/4 inch in and dual 2 inch out muffler Trans Am muffler
* 2 1/4 piping to a very long 2 1/4 inch resonator
* 2 1/4 inch catalytic converter
* an AEM true cold air intake NOPI edition
* 8 gauge ground wire kit
* Toyz front strut brace
* Russell stainless steel brake lines all around.

whatcha wantin to do this for? if ya don't mind me askin?

I heard from another member here that the 02-05 Ecotecs really work well with the DIS-2 ignition kit.
I know a lot of cars range from you cannot tell it even is making a difference all the way to 'wow'.

The member here says it really wakes up the motor.

I know the Accel coils are some of the highest output, and installing them on my old 2m4 Fiero really woke the car up.
I also had the DIS-2 ignition, so I cannot tell how much affect came from just the coil packs.

It sounds like it would be a good next mod, since my coils are 110+k miles on them and I believe replacement is going to be needed soon anyways.

When anything needs replaced, I always like to replace it with something better is mostly the reasoning behind this.

An external coil swap is more of a supporting mod on our cars, dont expect hp gains from it alone but more things like smoother idle and lower rpm driving, etc. Pairing them with the dis-2 is a good upgrade to get the most spark possible, but honestly with just a few bolt ons its not realy needed. Some people use it just for the 2-step though.

I plan to upgrade my 2200 coil swap with msd coils/interface modules and a dis-2, but my car is turbo and a built motor going in this year soo I want all the supporting mods I can use. What Im saying is this mod will benefit you, but dont expect the same results as a boosted or higher compression n/a build would that needs the extra spark.

I've never used accel but i dont imagine they are much different than msd as far as coils



1989 Turbo Trans Am #82, 2007 Cobalt SS G85

From all my research on the Accel coils over the MSD coils, the Accel's have a tendency to break down much quicker in their insulation causing weak spark over time compared to the MSD's.
I chose the MSD's with my setup and am also running the 6211 DIS-2 setup too. Love the way the car runs with this and how smooth everything is.
And like IceMike stated, this is a supporting mod that with boost, will help the overall spark of the car with less blowout of the flame from higher pressure boost setups.
Good luck with it.

Thank you Dave and JBO!

anyone have any info on 2200 coils swap on a eco i have a both a eco coil pack ,mod and 2200 coil pack and mod i looked the wireing up looks to be


eco wireing
time b -org
cam sig -brown/white
time a -white/green
ing -pink
ground black/white

2200 wireing is
match these to the eco wireing
time b- org
cam sig- brown/white
time a -white/green
ing - pink
ground - black

im gussing these are the ones i would not use
clip sig -purpel
low ref -red/black
ckp ground- yellow


i cant find anyone that has a write up on just the coil swap on ecotec so were just going to try it and hope for the best unless someone know how to go about doing this and would like to share it with me

I'm Listening.
What are all the parts needed for the ecotec?

in not sure as i have not dont it yet but im going to try to uses 2200 coils and mod with a set of plug wires im going to try this setup maybe tomorro after work

Having run a full MSD setup on my '88 Ramcharger, I can say that going with such a mod is well-worth it on even an all-stock ride with EFI. A 20% improvement in mileage and starting so easy, I just turn the key & it'd crank about half a rev & catch... No-matter how cold it was outside!

THis is very good to hear! I need to hurry up and do this seeing as my car is 100% daily driven year round. It will def be done before the built motor goes in.

I should go-on to add that when I did this... I used the following:

MSD 6A
MSD Super-conductor wires
MSD Blaster-2 High-vibration coil
Champion Truck Sparkplugs
Heavy-duty replacement cap & rotor

I gaped the plugs to factory specs (.035) and got 30k-mi out of each set.

You can use whatever choice of plug you like, but the harder-wearing the electrode material (With best conductive property through entire heat-range it'll see during operation) the better. I hear Brisk plugs qualify as such...

As for wires, get a universal set & fab custom length ones yourself. Why? No-one makes a custom-fit set for what you're looking to do (LN2 coil-set). Trust me, I know... They don't even make them for the LN2 all-stock!


Go beyond the "bolt-on".

can some one provide some part numbers for this stuff?

Oh yeah, one last thing...

Capacitive-discharge ignitions (That's what the MSD is!) eat-up amperage, so make sure the charging-system is up-to-snuff. My Ramcharger came with a factory 120A alternator, so I was covered. I just ran the heavy red lead to the battery terminal on the back of it (Yeah, I know... not proper practice!) with a bit of slack to insure the box got all the amps it ever needed. In retrospect, I should have also use a fusible-link & ran it directly to the battery. But, that was all the way across that wide engine bay... And I was short on free-time. So...

I am pretty sure I am going to do the full DIS-2 ignition.
It did so well on my Fiero, plus I have had a few endorsements here too.
The one bad thing was, the first DIS-2 box I bought was a dud.
Huge bummer to have it in the speed shop and find that out.
I had to run with the dead box to the place I bought it, exchange it, return with the new box which was a 60+ mile drive and then rescedule the install.
It was worth it though.
I might buy another 2m4 in the future, with a couple mods, it really did good on the freeway but felt like it was "anchors away" from a stop.

If there ever was a canidate for swapping a '92-'95 LN2 in (In my mind) it was the "fuelie" Iron-Duke'd Fieros. A lighter engine that produced 30% more HP outta less displacement N/A... Sounds like a big improvement to me! I'd go with the S-truck intake on it, if I could, to get more outta the hole.

I found a local selling a 4.9 Fiero fuel injected and almost bought it.
I thought my work was moving to an area where I would worry about theft and break-ins.
So I wanted a cheap car to take, but, have the fun of 200hp and 300lbs of torque in a light car.
I think he wanted around $3000 for it.
Money is so tight, I had to wait to see the new job site first, and it turns out to be a secure location.

4.9? STAY AWAY! That's Caddilac's old HT-series iron-head, aluminum-block engine. The one that had nothing but head-gasket sealing problems from day-1! Plus, I'll bet he hasn't put any mods on the car itself with consideration towards engine cooling... Namely, engine-compartment cooling. That becomes a big necessity when swapping-in larger-than-designed-for engines in the P-body.

Sorry if this is thread jacking, I am wondering with these accel coilpacks would be a straight plug in from stock coilpack application? I am looking @ a replacing my stocker coilpacks in my 01 cavy 2.2L ohv. Any idea's?


thanks for youre input.

Yes, they are... But for the money you'd be better-off getting the MSD's, which also bolt in place of stock.

One thing (Or two) I must mention before going is about the ICM coil-charging circuitry & MSD coils themselves:

The GM Twin-tower DIS ICM is designed with load-sensing current-limiting circuitry that dials-back the electricity fed to the coils when they sense a load of or nearing 1-amp. This prolongs the component life of the coils and, mainly, the ICM.

MSD's coils are designed to work with the multi-strike amplifier/discharge-controller box by being of "quick-rise" primary windings. Why? It takes time for time the windings of the coil to fully energize, and hey... the box trying to produce multiple firings in the time it takes the stock system to make one! The factory coil would be a "bottle-neck" in this operation because it just don't energize that quickly, so a coil with primary windings that energize quickly (Re: low resistance) would be necessary. Plus, the voltage output of the box would eventually cook the factory coil, while the matched coil is designed to handle it.
