Which coil for '73E?

[racemor]

I'm wondering if I really have to put down the $150-175 that I see listed for the correct Bosch coil for my '73E 2.4 motor. It is still using the original Bosch CD. Is there an aftermarket alternative?

iVE got a coil I bought new 2 years ago. $ 25 + ship Bought from Pelican for my 1970.

Thanks Paul, but that was my post there too. I was just trying to see what both boards thought for those that don't cross over. Looks like Warren thinks the Bosch blue would work...

IF you get a good one...I've heard rumors of them having mfg. quality problems. $pendy as they are, when the need arises, I think I'll go with old tried and true black with the brown top...

Hi:

Just my opinion, but I think "Brother Paul" offered the best advice,....

Coils are impedance matched to their respective amplifiers (CDI units) and while it does run, the Bosch Blue coil is really intended for non-CDI applications.

The fact that the car will start & run, doesn't make that the proper part for the job.


Short story:

Some time ago, we wre running a motor on our engine dyno with MSD's and Bosch blue coils. It ran OK, but not what we normally see for such a configuration. I mentioned that those coils were wrong and my compadre (Jeff G.) blew me off. After a frustrating day on the dyno with no improvements, he finally agreed to try the proper coils for the MSD's in use.

Voila'.....Power restored to "normal". It picked up 10-12 HP with that change. (I did refrain from gloating, tho)

Soooo,...its Caveat Emptor if you use a coil that is not the correct one for the CDI in use. I'll also mention that Permatune's do not seem as fussy about this as Bosch or MSD.

I hope this helps,

That does help, thanks Steve and Paul. I know that the phrase "you get what you pay for" is usually true.

Steve, from my description on the Pelican thread, does it seem like the coil may be going bad? It stands to reason that if it is leaking it should be replaced. But could it have anything to do with the hesitation/misfire? Over time, I think I've replaced just about everything else in the ignition, only a throttle body rebuild or pump work are left after a coil replacement.

Hi Tom:

If your coil is leaking, it will fail internally and short out. The result is a bunch of misfires until it fails completely and quits running.

Time for a new one, Sir.

Will do. Thanks Steve!!
