Best ignition upgrade

I have a stock ignition on my 1980 258. I was going to replace with a HEI since it is much simpler then the stock wiring which is a mess. However someone told me that this would actually give a weaker spark, and I should do a TR upgrade. Is this true, and how much time and money would ether upgrade take?

Re: Best ignition upgrade

I've been looking into the same things... Here's a site I've found you may want to read in reference the TR Ignition for the 258.

See the tech section on the left...

Good luck...

Re: Best ignition upgrade

Fot get HEI and DO the Teamrush TFI up grade. You and your Jeep will love it. There are those that like HEI and this is only my opinion. TFI is easy and can be done in 30 minutes once you have collected the parts.

Re: Best ignition upgrade

The TeamRush upgrade can be done for about $50-$60 with very common ignition parts readily available at ANY auto parts store. If you need more info, just let most anyone on here know, you can probably even get part #s. And by the way, many people use the TR upgrade to "upgrade" their HEI.

Re: Best ignition upgrade

TR cost Remy Dodge gave of $50 -60 seems a bit low. Below is what I spent not including the MSD upgrade which I later added. From following other posts it looks as though I may not have gotten the best plug wires but they fit well and work fine best I can tell. The basic TR upgrade (if that's what you call it)was perhaps the most improvement for the buck that I have spent. Here is my parts list for my 1980 258.

The parts all came from my local "Car Quest" auto parts but the boxes also say Standard Motor Products Inc. Part numbers should be able to be cross-referenced by your local store. TR has always manitained that you should buy the very best quality parts you can afford.

Coil FD478 $45.67
Rotor FD118X $ 4.77
Cap FD151X $27.99
Cap Adapter FD155 $ 6.99
Pigtail socket S539 $ 12.18
Plug wires 6643 $28.54
Spark plugs (6) Aut945 $6.24

Re: Best ignition upgrade

The HEI does produce more spark than stock, but less than the TFI (TR) ignition. It is much more expensive and complicated to do. I've done them both. I put HEI onto my '89 Wrangler because I didn't know about the TFI upgrade at the time. Later, I replaced the points ignition in my '74 DJ-5c with a TFI system. There really is no comparison between the two, the TFI is far superior!
