Does upgrading the iginition on an rx-7 really do anything? I heard that stock is hard to beat. I also heard that a nice upgrade is Jacobs Electronic's Rotary Pro Pak. Does anyone know if its worthwhile to a 88' gtu slightly modified.....intake,exhaust,pulleys,wires,airpump-a/c removal and weight reduction.:smile:

 

I really don't know that much but, I think that it can't hurt to have a cleaner more accurate ignition. My .2$ :dontgetit: I personaly plan to upgrade my ignition before I do my turbo upgrade along with bigger injectors. I feel that if the engine can get and use the fuel correctly I'm better of safe than sorry(detonating),not neccisarily that it will happen, :smilewinkgrin:

 

an ignition amp is unecessary! it might help low end a little bit but IT will fry your coil! i am running all stock igntion i took my amp out since it fried my coil the stock system is good for 600hp

 

Well i was thinking about getting the Jacobs Rotary Master Pro. I wasn't looking for an amp or hotter spark, but more on time precise complete combustion. Rarely when i revv my car high( past 7 g) i can hear a miss or backfire after i lay off the accelerator. I figured maybe that its not getting all burn or the sparks aren't 100% on time. And i Figured that maybe this happens sometimes or all the time at a lot less amount. U can't always hear everything with mufflers. The Jacobs Claims that all their product will:

Elimate ALL

1.Misfires

2.Poor MPG

3.Erratic Idle

4.Sluggishness

5.Bogs

6.High & Low End Miss

7.Hard Cold & Hot Starts

8.Surging

9.Plug Fouling

10. Weak Low End Torque

11. Pinging

12.Bucking Off Idle & More



It does all that. That would definatley mean longer life of your engine. And a little more hp. I know its a little spendy $365 :frown: , This is why i posted this..........

They also have their own coils so u can't fry em'.

 

We use MSDs on the SCCA ITS cars. Anything you can do to create a bigger or hotter spark consistently is a huge benefit. More air and fuel through balanced injectors, Etc plus a nice fat spark in the hole = more HP

 

Do u have msd coils, or just the amp on those SCCA cars? but then again those cars are really modified. I don't even have a turbo let alone 356 dollars to blow.

 

use the Jacobs pack...it is complete w/ the plug wires and the box....including the instructions....rx7.org

 

And the Jacobs won't fry my coils?

 

No.....I have have the unit in another car for about 6years now....never have ANY problems...OEM quality..
