Question Anyone doing a Coil on Plug setup?

I am not sure where to put this since there was not ignition forum so if it needs to be moved then please do so

Anyways,

When I had my 3000GT VR4, a popular mod was the coil on plug setup. IIRC the mod was using coils from a GSXR, I can't remember the details, but many converted to it. Is there a Coil on Plug mod for LS?

Thanks guys!

our setup is pretty effecient... the wires are like all of three inches long haha... plus space is a big issue, im pretty sure my motor rocks enough even with poly motor mounts that anything longer than what i have now would hit my heater box on the passenger rear of motor..

Comp Cams makes a standalone coil on plug setup for the LS motors.

XIM
Standalone
Coil-On Plug Ignition Kits
Air/Fuel Ratio Module Kit
for SuperFlow Dynos

The engineers at FAST
have taken the XIMto a whole new level. The coil-on
plug ignition controller, originally developed for use with XFI
systems, is now
available in a standalone kit. These kits will enable programmable control of
the popular late model coil-on plug ignition systems, independent of the fuel
delivery method or any factory computer. The standalone XIM
can be custom
tuned as desired with the easy-to-use adjustment dial pots. This bolt-on
solution to coil-on plug ignition is the easiest and most reliable way to run a
carburetor or EZ-EFI
on GM LS engines. Complete kit, does NOT require XFI

or OE computer. Ready to run, tuning optional.

i do not think the coils will live for too long if you do a coil on plug setup on a ls series motors. the coil will be to close to the exhaust manifold. plus the boot on the sparkplug is already in a spot where it will need to be replaced from time to time, and it will be very expensive if you have to buy a new coil every time the boot goes. it will pretty much the same for all pushrod motors (exept the new hemies) on most overhead cam motors the sparkplug is in the middle of the head where the temperatures are no where near as hot as the ones you will get beside the exhaust manifold. so the boot and coil will live for a much longer time.

Hmmm.... Good point, I did not even think of that. Need to look into the spacing and unit itself. Might call Comp to see what they say about this.

I just worry about spark blow out on turbo setup and sooner or later the LQ4 will getting a boob job and have itself a set of twins, lol,

^^^ personally i think that if you try to space the coil further out with a longer boot, it will kill the whole point of it.

i have not experienced spark plug blow out yet even at 13psi of boost, but i have experienced my spark plug boot melting on my turbo header. and if i did not catch it in time i would of gotten all the spark going to the block instead of the sparkplug.

no you dont understand... our setup is like.. over kill to the max, think about it, distributor cars use a single coil for all cylinders, they need a slight improvement in high rpms... our cars have 8 coils, 8 times as many working 1/8th as hard... search msd coils, they fail big time. they make less power and cause alot of blown engines because they misfire... stick with stock, youll be fine. oh and dont get truck coils.. its a myth thats been busted on here...

youll make zero power upgrading... its a big waste of money and your time...

oh and you wont get blow out if you pick the right set of plugs with the right gap, just get the right heat range for your set up....
