I'm wondering weather or not to put in a crane Hi 6 or go with the HKS twin power pack .I 've read that the crane will burn your coil out. I never read any cons about the HKS unit though. Any suggestions?

The HKS does both leading and trailing, and it comes with a harness that lets you install it in 10 seconds. The crane will only do leading. You'll need two more to do the trailing.

Hmmm I didn't know that.

Have you heard anything about the short life span to the coil as a result of using either?

I've heard of the Crane doing that, but it may have been an older version. Everyone who has the HKS system seems to love it.

Thanks

The nice thing about the HKS unit is that it's so small.

What about running a MSD 6A on the leading. Anyone doing that? How is the install....is it a pita??? I'm not so worried about trailing, I just want something for my leading and I can get a 6A from someone for cheap.



What do you guys think?



STEPHEN

That will do a good job. That's what I used to have. You just have to wire it up for power and ground and then tap into the stock wiring.

my car has three msd 6a's https://www.nopistons.com/forums/pub...DIR#>/wink.png

According to Mazda Sources the trailing ignition is only 10% of your HP and more or less a cleanup for emissions.



I was wondering about the new Mallory HyFire. It's about $120 but I'm not sure it would work with the Mazda.

I know some Rotorheads use MSD's 6A and others use Cranes Hi-6

If you guys run a search for Carson (his name is Spyfish007 on the "other" forum) he has a post in the last couple weeks about his leading getting fried from a amp box. I THINK it was the Crane. I never knew that they actually fried, I thought that was a figure of speach but he has a pic and it was actually burned looking on one side.



Anyway, you might want to do a search for his name in the 3rd gen section over there and confirm what box he was using.



STEPHEN

Do a HKS dude. I have a crane but it was cheap that is whyI did it.

They work well, but they take up so much damn space! :o

I talked to the Crane rep at one of the larger shows, and they said that the HI-6 that everyone seems to run is a short duration, high energy spark - basically capacitive discharge ignition just like the MSD.



Their new HI-6S gives a longer duration, slightly lower power spark (still much higher than stock) - an inductive ignition.



both give multipule spark below 3000 rpm and have built in revlimiter, but the HI-6S is a bit cheaper and smaller.





Our rotories use such a bad cumbustion chamber shape that a longer duration spark would help burn the mixture better. If I had to buy one, I'd give the HI-6S a try.



My $.02

yeah, spyfish was using the Jacobs ignition amp.



I've heard with the Jacobs, you should use their coils... https://www.nopistons.com/forums/pub...IR#>/smile.png

From what understand, the jacobs amp/coil is a good set, but expensive.



The HKS is the EASIEST, SMALLEST unit.



The Crane HI-6 seems to give Power FC user's problems.



Never touched the MSD units.

We need to get tot the bottom of this because I heard justin say Crane does not want anyone to use there ing. systems on our cars. So anyone else heard this?



-Rikki

i never heard of a problem with the msd boxes

Keep in mind that I was asking the rep about my application. The 3rd gens computer controlled ignition may be a different story.



Side note - My damn MSD scared the crap out of me the other day (forgot to tell ya this one Rikki). I put the new oil cooler on and disconnected the trigger signal to the MSD so I could crank it without starting just to get oil through the new cooler and build pressure first. When I let off the key, the damn thing lit off the dual post coil and blew a 4' flame out the tail pipe in the garage!! I had to change my shorts! It was LOUD.



Any how, I've found that the MSD will sometimes send spark to the coil when the ignition is just turned on or off. Kind of a random thing, but it may not be good for the seals to ignite while sitting still ?

Search the other forum in the single turbo section for ignition setups. There is a bigg long thread and towards the end is where I got that info. I don't know from personal experience.

Sometimes when you turn the ING on the coils do fire off. That is normal but it really should have not blown a flame. Coils do fire off but it is controlled by the ECU.



-Rikki

i love my jacobs.....kicks ass.

I had a jacobs on an old honda I had for better gas milage. I asked them a few years ago about a setup for a rotary and they didn't have one at the time.

rotary performance sells the jacobs rotary pro-pack. i think that it is around 600$$



WOW!



either way, i think that this is the unit that i am going ot go with...



lou

I've heard good and bad about the Jacobs unit...BUT after seeing it 1st hand, I wouldn't hesistate on picking it up if the price was right. You have to get both the coils and igniter though since the jacobs igniter will fry the stock coils. https://www.nopistons.com/forums/pub...DIR#>/wink.png

how will it fry the stock coils? ****. i need to hear as much as i can for the future purchase of this unit.

I use two Crane Hi-6's and two LX92 CDI Crane coils, one for each leading spark plug on my 566bhp 13B Turbo, I run 11 heat range plugs with premix + metering pump + water injection, this is hard **** to fire !!! The Crane set up is first class !



I have been running it now for almost 6 months (daily driver) and the only down side is that it is very hard on the ground electrode and the center electrode, it wears the plugs out about 10 times as fast compared to stock of transistor type non CDI ignition.



But if you are after performance and want to be able to fire a "cold" plug with out having a cold misfire or not take the risk with running to hot a plug cause your ignition is not strong enough then CDI is the go.



I realy love my Crane set up, I highly recommend that you use one box or cahnnel per leading plug, do not divide the energy over two plugs or coils.

High power (and most of the low power!) boys here are using the inbuilt igniters in the Microtech to fire off 4 or 6 individual DFI coils from Bosch (built especially for Ford for one of their common models) with no breakdown even up at stratospheric rpm..!

the haltech fires the ignition when you turn it on, sometimes its at the right place to fire and move the engine



mike

So does the Microtech.

I use the bosch coils HEC715 for my trailing fired by BOSCH 008 ignitors, they work OK, cannot compare to CDI though.



True many things make power, but you sure as hell cannot get transistorised ignitions to idle all day long with 11 heat range plugs ! Also they are not tolerant of rich fuel mixtures, alot of the high HP drag guys run VERY lean for a turbo engine wich reduces the amount of energy required from the ignition system to fire the cocktale in the combustion chamber.



Very high pressure ratios and rich mixtures need a strong spark for maximum power.



CDI is the king, the only problem is all of the good ones cost quite a bit of cash : (

I have been looking onto ignitions for a while and here is what I have to say. Direct fire is what everyone should do, It makes more power. period.



I like the MSD boxes but they are build messy (take a look inside of one sometime)



I dislike Jacobs products (they work great untill they blow up, my buddy went through 4 (FOUR!!!) Jacobs boxes in 2 years, everything was hooked up correct, and he was using everything that jacobs told him to use, spark plugs, wires, etc.)



Crane and Mallory make good, well built boxes, even with rev limiters



I would prefer the MSD 6AL because of 1 certain feature. The plug in rev limiting chips. Although it is not as convinient as some of the other boxes out there, it is very flexable. MSD sells a 2 stage rev limiter that will plug into this slot, so you can set staging rpm and top end rpm. MSD also sells a RPM limiter dial that will allow you to set your rpm from the drivers seat. Just imagine, being able to make split second changes to your launch rpm and top end rpm from the drivers seat. I don't know of any other box that will do that.

for infor on stuffing a Mazda rotary engine into a VW bug, go to my website: http://www.geocities.com/zenjoe/vw.html

Dave, keep it stock. I had the HKS and didn't notice anything. I've still got my ignition stock and runnin 10's :bigok: If you do get anything, get a MSD digital 6 for the leading. Keep trailing stock. Its not a concern. Demetrios ran 10.1 on leading only. (Trailing wasn't firing at all)

Thanks Ernie, I like that suggestion best. It means I don't have to buy anymore **** that costs a fortune.



God help me next season when I hit the track.



I'm gonaa get slammed by you guys for my hurting ass 60 ft. https://www.nopistons.com/forums/pub...R#>/violin.gif



I wanna play too :twisted:

i run the msd 6a and bypass the igniters on my 1st gen 13b doesnt burp when turn the switch on.

quick question

you guys r just adding cdi boxes to the ignition to make it better right

i just bought a 12a but it only has the distributor so i have no clue as to how the igntions connections are made i am guessing that there is a signal wire from the distributor that triggers the coils but i read that the is some igntion box or something stock

also couldnt i just use like 2 accel super stock coils for coils or is that a no no

also has anyone tried the 300+ series accel ignition system you get a good coil and the box for $210 i am new to this and i want to get it running

thanks
