I'm looking to upgrade my coil packs on my FD. What options are available out there? or what are you high powered rotaries using? Any help would be highly appreciated.

Many people use T2 coils. They are a good alternative.

 

stock + twin power

 

yep.
Stock coils, 9's all around, and Twin Power

 

how much power are you looking to make?

 

Is there anything better then "upgrading" to a T2 coil lol?

Love these coils. Have used them on a couple cars with good results. There a bit tricky to mount in an FD chassis with PS and AC but it's doable. The LS1/2 coils are also a good option depending on your power levels.

right now im makin 450 on pump. Going to tune for more on race gas.

 

stock coils + hks here. 617 rwhp. BTW you made 500 on race gas.. Were you not happy with the tune? I thought Ray let it run out on the last pull?

 

If you want a real upgrade.


Crane hi6 boxes X2 for the leading(one each) and 2Xlx92 coil packs to go with the boxes.

And wack in a set of trust r7420-10 plugs.

BEST IGNITION SYSTEM PERIOD>

 

More info on this ignition system. I already use the Greddy/Trust Iridium Racing plugs (r7420's).

lol. Mike you know there's never enough power lol. I want 600whp like you

 

Got a friend that make 630rwhp on stock T2 coils.

 

There is a reason Mazda went with two different heat range plugs, same reason they have two different size spark plug outlet holes..... "9's all around" may be the popular "mod", but it doesn't mean it's correct.

Would you care to divulge more on this topic via PM? I am genuinely curious.

 

7 leading and 9 trailing usually runs cleaner and smoother. Especially noticed during cold and hot starts, engine starts very easily. Running 9's all around, there may be cases where it might be harder to start but will eventually start. Running 9's is safer for higher power applications or extreme use since the plug dissipates heat quicker. If your running near stock power I recommend the stock setup regardless of what others say.

I personally run Greddy Iridium Race plugs (rebadged NGK R7420's) with 9 leading and 10 trailing and seems to run pretty cleanly (I take a look at them occasionally to make sure they are ok). The reason I choose 10 trailing is because when I opened my motor it seemed like the area near the trailing plug hole was heat scored so I'm trying to get more heat out of there.

What you need to know.

I have used MSD.
M&W CDI.

RICE RACING was bashing on about the cranes along time ago.
First WI car i did, we used the crane setup on it. And have never used anything since.

Unreal ignition.

Just to give you an idea.

This is what the above setup has been able to burn through with 0 break up

1.4 litres of water per minute(water injection), 10:1 AFRS and 30psi of boost.

 

Has anyone actually run any different coils with the stock setup/twin power? I am running just leading plugs with the trailing coils and everything is great till about 20-21 psi on C-16, then it starts breaking up because I think it is just blowing the spark out. I was looking for a hotter coil alternative. I have heard of RX8 guys using MSD LS2 coils and have read on their forum that they actually had power increases simply by switching to these coils. I would like to know if anyone has used these.....

 

I am very onterested in this these coils or the LS2's. Do you know anyone that has used them with the stock setup? What do you mean by "depending on your power output". Why are they tricky to mount on the FD? They appear to be smalled than the stock coils.

 

anyone?

 

I haven't heard of anyone using anything except the TII coils and the stock coils with the twin power. I'm using the stock coils with twin power currently. I'm at 16 psi and 350 cc of water without issue. But I might be looking for some better coils as well because I plan to go over 20 psi and higher water flow, but I don't plan on spending $1000+ on ignition upgrades.

gilesr6 what plugs and turbo are you running? Keep us updated with what you go with and the results.

 

Actually this is not the case at all . Fact of the matter is, runnig "9's" all around is NOT safer and does NOT dissipate heat quicker. It is quite the oppisite bud.

9's are a colder plug then 7's so yes 9's all around would allow the plug to retain less heat that could potentially ignite the mixture prematurely. The problem is colder plugs tend to foul easier.

 

That's not the point I'm making here. But thank you for a lesson on what the different heat range ratings are for on a spark plug. Please see post #14.

Do you have any info regarding what you're saying J? Saying that Mazda did it for a reason can't be the be-all end-all answer to this. Mazda also went with a 3-piece Apex seal.. Point being many things were done for emissions standards, long-term reliability or production costs, things which the average racer does not always have to account for.
