Re: MSD or Jacobs ign. upgrade

Jacob's customer service sucks. Go with the MSD. Do a search on: "jacobs customer service" on this board.

Re: MSD or Jacobs ign. upgrade

Awh... heck... save all your money for something else... start out by doing the TR Ignition upgrade... best bang for the buck. Then if you want more... go for the MSD. Just because it's cheap doesn't mean it ain't good.

Re: MSD or Jacobs ign. upgrade

I agree with WILL & LEVE. MSD technical support has been great for me (I'm a pencil-pusher who likes to tinker. I've learned more from my mistakes than my accomplishments, but I'm a better man for it). Team Rush upgrade - my first major undertaking since the "Nutter Bypass" - has shown a tremendous improvement in fuel economy (from 13 mpg to 15 mpg), and performance. I'm certain the MSD will show an equal improvement. I'm still trying to determine the best way to install mine (via Distributor Harness, direct to Coil, keeping Duraspark hooked-up or disconnected, etc.)

BTW, do you still have the Carter BBD? Do a search on it, as well as the Motorcraft 2100 & Rochester carbs. I'm rebuilding the Carter next weekend (I'll give it one more chance, then I's switching to the Motorcraft).

Re: MSD or Jacobs ign. upgrade

OK, Leve and Sahara I tried to do a search on the TR ign. upgrade and the "nutter bypass" couldn't find them.Sorry for my ignorance,but can you explain,or send me in the right direction? I'm getting my SYE kit next week and 4.56 gears and a posi in back this weekend so I was hoping to get an ignition upgrade while I've got it tore down.I do have the BBD carb (2nd one)likes to die,spit and sputter on occasion,thats another upgrade on the wish list in the next couple weeks.Thanks for the input!!!!

Re: MSD or Jacobs ign. upgrade

Jacobs got a good review, but I have gone through 3 coils during hardcore offroading. They replaced them for free, ut its still a hastle. Fort my .02 I would personally go with the HEI upgrade....~TIM~~

Re: MSD or Jacobs ign. upgrade

[img]/wwwthreads_images/icons/smile.gif[/img] From our perspective, the TR/MSD upgrade seemed to be the best way to go.[img]/wwwthreads_images/icons/smile.gif[/img] We were all set to convert our 304 to GM HEI because we have had so many V8 GMs with that system, and as long as you have a SPARE ROTOR in the glove box, you can usually get home[img]/wwwthreads_images/icons/crazy.gif[/img] Once the TR upgrade was developed,[img]/wwwthreads_images/icons/tongue.gif[/img] we began to think about going with that system, but the possibility of module failure was always in the back our our minds. We didn't want to have our CJ quit when the feds were after us for having the last private firearm in the US. (Now, remember, we did this when the Scumbag was in the oral office and it was a distinct possibility that Scumbag II would follow him and begin grabbing guns)[img]/wwwthreads_images/icons/frown.gif[/img] WHAT WE DID WAS install a special distributor built by the technicians at the TeamRush Ignition Laboratories; a distributor which had TWO ignition triggers in it (like fire trucks, ambulances, and NASCAR racers use), one triggers a stock Jeep module and one fires an MSD 6A. We used two TFI coils and a tricky coil selector like the NASCAR guys use. A dashboard switch selects which system we use. What this setup gives us is the sustained, multiple, high-energy spark from the MSD, and a totally redundant, but STILL high energy spark system utilizing the Jeep module as a base.[img]/wwwthreads_images/icons/cool.gif[/img] When it comes to sweeping out those dark corners of the combustion chamber, it's hard to beat the combination of sustained multiple spark from the MSD, coupled with the TFI-Ford TR conversion for high energy. Truly; as LEVE has told you; a good bang for the buck.[img]/wwwthreads_images/icons/smile.gif[/img]

Re: MSD or Jacobs ign. upgrade

I would stay away from the Jacobs and go with the TR upgrade instead. I put a Jacobs kit on my CJ when I first got it and noticed a much smoother idle and slight increase in power. After about 2 years it took a dump on me. This is on a trail only Jeep that only sees about 500-750 miles a year! I then went with the TR upgrade and noticed an idle that was just as smooth and a bigger increase in power. And all this for a fraction of the cost of a Jacobs kit. TR also has much better online customer Service too!

Re: MSD or Jacobs ign. upgrade

I ended up using the Crane electronic ignition that uses an optical trigger (shutter) with the Crane coil. It was under 130.00 for both to my door. Biggest difference is smoother idle, quicker response, little more power.
