i was wondering what the pros and cons are against each of these units... why i should get one more then the other? any ideas would be great.

 

i am going shoping and i would love to know what people think and what there experences are.. i know that jacobs is more expensive.. but is it really worth the extra money.. i could probally get 2 MSD units for the price of 1 jacobs...? ideas........

MSD

 

i got the HI-6. better than the MSD, but not nearly as pricey as the jacobs

 

I believe that the Jacobs has more power. check their websites for the tech stats.

 

My older bro told me about the jacobs long before I even knew about 7s. He said its a great system. Just no one really ever shows any dyno sheets proving any ign. comp. give you any real gains.

 

rx7.com swears by them, i beleive that they have a better spark, but they are also the only ones made for rotaries, ie rotary pro pak

 

YA THAT'S THE ONLY REASON I GOT THE JACOBS ON MY LAST FC was the claims from them i know they are very reputable so i wouldn't say they are lieing. but, when i installed the system it wasn't as good as they say i didn't feel the gains they promised although i wasn't heavily modified with the gains they were claiming you would have felt it. also i experienced an intermitten starting problem that i spoke with someone from rx7.com who i boutgh the system from and they told me it's common you have to plug the stock system back together start the car and then plug the jacobs back in also i was getting a flooding problem with the system and was told at the time (same conversation) that when shutting the car off you need to rev to 6 or 7 grand and turn the key off when the engine is at 6 grand to aleviate the problem. so to sum this up i have not tried the msd or the crane ignitions but i don't like the jacobs.

 

revving the engine to about 1500-2000 rpm is more than enough to stop the flooding problem. Do not rev to 6k and shut the engine off. Very bad. Very, very bad.

 

They used to claim 7hp increase

 

hey soul what Msd box do u have.. i brought it down between the 6A and the 6T.. the only thing that the 6T has that the other one doesnt if reinforceing.. for 80$ less i think i might go with the 6A.. since im getting 2 i dont wanna blow all my money ...... what u guys think?
