Wolf v4 ignition coils/ ignitors ???'s
 

RX7 turbo II


I am trying to decide between using 4 INDIVIDUAL stock 2nd gen coil or use a coil / ignitor combo. Although the Mazda coils are great (reliable, powerful, easy to find, & CHEAP!!!) they are bulky and will require four ignitors to control them (also adding to the bulk). So my questions are as follow:

• What reliable & powerful coil/ ignitor combos are suitable for rx7 turbo, where to buy them (junk yard cars do apply i.e. off of an old GM, BMW, ...)?

• Where can I purchase the Wolf recommended bosh 0 227 100 200 or 1227 022 008 ignotors (I would prefer new clips that I can wire) but junk yard cars do apply?

• Any ideas on where to mount the ignitors if that is the route I take (I am trying for a clean looking engine bay)?

Thanks for all of your help.

First, id like to say the search feature is your friend. Second, you only need 3 igniter channels to power FC coils because the leading is a dual post.

Now, back to point 1. Get an FD Igniter and FC coils. It will save you a lot of money and headache.

Here is all the information you need:

I done it the hard way! Individual ignitors and coils by bosch. Next time I would use series 5 ignitors and s4 coils as nyt said as the Mazda coils and ignitors are cheaper and more reliable than bosch ones. They are also so much hotter!!! :squint:

Everyone learns HERE !!!!

Although I did find both of your replies helpful as stated earlier I was not looking to run the dual post coil, but rather 4 individual coils

*shrug* its good advice youre ignoring.

if you want to do it the hard way, wolfems.com has everythign you need on the site. good luck.

Rule No1 Bosch ignitor gets wet kiss it goodbye.
Reason : the High tension emf can leak into the primary coil driver and it does, it is designed to take it>However the pickup side can not handle any over voltage. Water casues current and voltage to leak over into this circuit and it is DEAD CACTUS KAPUTT...that will be $70 thanks for coming.
Rule No2 Bosch ignitors are designed for Bosch coils.
Reason : Even though a coil may have the same resistance it's dynamic response can be different. Its called impeadance or resistance verses frequency
Rule No3 : Keep them cool use a large heatsink.
Reason: they last longer
Rule 4: Supply heaps of power to them they draw 8 amps each so don't be shy with wire size and fusing.
Reason : Low voltage = piss poor spark and boost flameout

Rule 5: All the previous rules have come from ME making these mistakes. By taking this onboard you will save money and time :)

so what do we think of my FD ignitor with (4) MSD Blaster SS coils with 1 MSD 6A for the (2) leading coils?

is it gonna be a problem? (I have a wolf v4) (BTW it's a 89 t2, zip-zero-zilch is stock...absolutely nothing except stuff like wiper motors)

kevin.

I don't know....but I do have a little experience with bosch coils and ignitors right back the first one used by Holden/GM in their hei 6 cylinders. Just workedit out, thats about 22 years! shit I getting old!

I ran that setup in my FD, but the blaster coils were crap so I went back to FC coils. btw I have 3 MSD 6a's on that setup. There was plenty of juice. Now i have like $300 in coils sitting around collecting dust.

really the blaster coils are no good? so id be hurting my setup more then helping it? any other coils that would be better?

could you maybe draw me a diagram of how you did the 3 MSD's? that was what i wanted to run at first but everyone said it was pointless...

with the blaster coils am i gonna have ignition breakup? im building a large streetported 89 t2 with a t78 and aiming for around 500-600hp...id prefer to kill a problem before it happens.

Hey guys thanks for your responses and personal insight.


I think I am going to go with a combination of my original idea and a set up that was referred by Michael Smith & NYT, 4 individual stock FC coils and M&W 3 channel ignitor (why M&W Ignitions? I will explain).

• I cant find a 3rd gen ignitor (or anyone willing to clip FD harness)
• The price that was given to me locally (***if they had it***) was ALMOST the same as a new M&W product
• M&W Ignitions comes referred by just about all of the EMS manufactures
WOLF, MoTech, Haltech, Microtech, AutoTronic…
• Brand new product $150 US (Harness Included) w/ warranty

http://www.mwignitions.com/

i wasnt even happy w/ how poorly the blaster coils started my engine. as for the FD, its just the 3 outputs to 3 haltech msd 6a boxes to the coils, nothing special.

FD Igniter is really the way to go, were using it in cars that are making 700hp.




as for trouble finding an fd igniter post a WTB in the fd section, I got one for like $30 shipped.

also if youre using a 3 channel igniter, i think your best bet would be with a dual post on the leading.

My old Mazda Coil(S4) would throw a spark 10 -12 cm about 5 inches my bosch coils are lucky to see 4 - 5 cm about 2 inches. Thats a big difference.
Don't be afraid to ask for help if it doesn't work as well as you like, we are all learning here. After looking at the CDI's offered by Mw ignitions I should have kept making my own. My ignition used 2 Uf storage caps with 800 Volts into the primary it would blow holes in 90 degree boots and then jump 8 inches :jump: you didn't even need to have a top on the sparkplug it would jump all the way to the piston. It was hungry 30 Amps :drool: . but very deadly it could easily blow a hole through your hand. I used it for 2 stroke outboards.

ok well i have an fd ignitor and (1) MSD 6A....is the general consensus to stick with my stock fc coils then? i hope i didnt give them to my friend lol.

kevin.

thats what I use. ignition is incredibly clean with this setup. in fact i kick myself in the ass for all the crazy ignition systems i tried, and try to prevent other people from making the same mistakes

as for the issue with nobody wanting to clip there harneses, i forgot to ask for the plug, so my ignitor is plugged together with spaded connectors and then coverted in hotglue

2 years and counting and it runs fine

alright so wolf v4, fd ignitor, stock fc t2 coils (1 for both leading an the individuals for the trailings)...and how many msd's? im trying to avoid any possibility of ignition breakup when im shooting for 600hp hopefully early next year....if fedex gets me my money for my lost housings.

kevin.

ouch.. sucks with fedex. i refuse to buy stuff with fedex personaly


one msd 6a is suppoto be prettty damn close to as much as you can get

a thread i read earlier today was something to the effect of "an msd on the leading coils gets you 95%, putting one on each trailing gets you the rest"

thats about right. msds on the trailing seem to just suck more juice than theyre worth

alright...so who wants to buy my 4 blaster ss coils?

kevin.

^^lol^^

ignitors ??
 

Use 1 leading ignitor on each coil. (second gen) series 4, series 5, turbo or N/A
If you open the base and compare them , the ignitors are the same just the wiring is diffrent. I used this setup with 3 MSD 6a's

would anybody have a blueprint on how to wire up the FD Igniter and FC coils? i will be useing a Autronic SMC. thanks
