I know the factory coil packs are a good design, but are the MSD any better?

Are they worth buying for a future 415/416 ci build?

From what I hear and have read, they are not worth the price, on any build. Plus I think they're ugly.

i bet if you didnt know if they were or wernt on the car you would never know. the stock coils are more than enough for the task IMO

So, no they arent

no. but the coils used on LS2, L76, L92, and LS7 motors are supposedly better than the ones used on our LS1's.

Can anyone speak for this/confirm?

We have taken out 2 set of MSD coils out of builds done at my sponsor's shop. Went back to stock coil packs. No problems. We have used LS1 coils in a Mustang, Toyota MR2 and numerous other turbo builds. All with no problems.

dont even think about them

I have a set of perfectly fine LS1 coils and was just wondering since I'll be going with a radical L92 build in the future, if I should consider upgrading.

Why are the truck coil packs so popular?

The MSD coils I have heard are used in FI applications. They help burn off extra fuel as they are multiple spark per singal.

I can't vouch if they will make your MPG go up or whatever because I went to an extremely cold plug at the same time for nitrous. I didn't loose any MPG though you think I would with a plug like that.

I was dumping fuel in on nitrous runs and the plugs looked great.

I won't be running FI or nitrous, it'll be a N/A motor, full out race. I was looking for an alternative if there was something better.

Why do so many people swap to truck coils?

My guess is they put out more energy more like the costly MSD coils just not multiple spark. Plus, truck stuff is always designed and built to be tougher. More energy, better spark, better ignition.

I run stock LS1 coils.

I believe the differece in the new and old factory ls coils is that the new ones are more efficent electrically, less amperage to get the same amount of spark output. Just use the newer factory coils.

Well they stopped making F-bodies in '02, so what "newer" coils are you referring to?

"newer" as in the later genIII and genIV motors... they didnt stop building motors when they stopped building fbodies.. lol.

if you swap, you'll need the coil pack harness because the coil connector is diffrent.



but its pointless.
the fact is, the stock coils are strong enough to light off a 6second boosted race car.

when you start reaching stupid levels of cyl pressure, (we're talking about, worried about lifting the heads level).... THEN you go into the PCM with your tuning software, and adjust the dwell settings for the coils.
thats it.

other then that... you dont have to worry about the ignition system on your motor... you have 8 fullsize coils, one for each cyl... its so ridiculously overkill that its almost funny.

dont worry about it, and spend your money elsewhere.

I know LSX motors are still being produced (SS Trailblazer, C6, etc.) Heck, most the motors GM puts out (performance V8) are based of LS series. I was just wondering from what model I should consider these coils.

MrDude_1

iTrader: (4)

well, the truck coils, and other later model coils are physically smaller.. so if you want to hide the coils for looks or something, they work good.

otherwise, like i said, it really doesnt matter. you will see zero diff in ET, trapspeed, top speed, horsepower, or handling.

Nooooooooooooooooo

just and FYI something about the computers the LS2 coils don't like working on LS1's I've heard.
