Ignition Options

[33GTRV]

Hi guys and girls, after a brisk search through SAU and reading the coilpacks thread i am going to be sticking with OEM coils in my build, BUT, i am wanting to go to an ignition amplifier such as an HKS Twin Power DLII unit or similar. Now, my query is, what is available on the market these days and what are the costs of purchasing them? I have heard of a few workshops using thier preferred items but not too many wish to disclose any details on them or dont return calls regarding questions about them. So, in summary, i want to know what is available in the ignition amplifier world, what it costs and the ease of installation as i am a hands on kind of guy

Cheers, Allan

What's the setup/how much power are you after? Are you having ignition troubles ATM?

I had the Twin Spark on my car, ditched it and I'm now running a box which replaces the OEM ignitor.

Hey paul. Im going to say that im going to be chasing upwards of 500awkw in the forseeable future. For the moment im looking at mid 400's with the current turbocharger, hopefully. i have heard of Yavuz using his favourite black box, but ill be buggered if i can find a great deal of information on anything of the sort and yavuz seems to be a busy man, which is understandable. People like yourself are the people im looking to pick brains from, real world experiences, realworld results.

Cheers, Allan

I'll go to PM.

Ls2 coils or bf ford coils depending on the ecu... At the end of the day when you are talking about inductive coil setups it's the coil that is the limiting factor - not the box that charges the coil.

I've used bf coils on a 30psi plus 2jz with great results running around .95mm gap. Have also run ls2 coils on tt427 lsx motors up to around 20psi with 1.2mm gap.

hmmm. Thanks for the input rob. Whilst using LS2 or BF coils is not my ideal setup at this current point in time (wishing for the engine to look as unmolested as possible) i will definately keep it in mind. I would much prefer the coil on plug type setup so i can use the engine ornament/coilpack cover plate to keep things looking tidy.

Thanks again rob,

Cheers, Allan

Keep it simple. Splitfires are proven well over 500kw.

Bf coils are cop all you need to do is cut the boots in half and Add a laser cut plate(or a phenolic plate) - absolutely no reason you can't run them under the STD coil cover for less then half the price of spitfires. It will depend upon you ecu though.

Ive never run spitfires any where near that sort of power - not saying that it can't be done but I wonder what the plug gap would be .6mm?. IMO if it's a street car and you want decent drivability/emissions and plugs that last more than 1000km you want minimum .8-.9mm gap.

point noted rob. I will definately look into it. Thanks again for the feedback mate, its appreciated. While i respect the fact that there are the "Splitfires are great" brigade, i also have noted the fact that i have not seen one BIG HP GTR in JP that runs splitfires. They all seem to run OEM coils with ignitor mods or run the OKADA or similar Plasma DF coils which may i add, are prohibitively expensive. Please guys and girls, keep the ideas coming! This thread will no doubt benifit more than just me in the future

OEM/Split fires are near enough to the same thing.

People don't use OEM simply because they cost more (call Nissan Aus and prepare for the hernia). Gotta remember the Japanese love their catalogue book of parts

As for driveability/emissions... Can't really see how that's a concern with 500rwkw.

[KiwiRS4T]

Has anyone tried the Okada coil packs? I don't believe they are that much more then OEM although I didn't go so far as to get a quote. But anyone have real life experience with them?

[33GTRV]

if i remember correctly, elrodeo was saying they were somewhere in the vicinity of 1700 landed here in aus so they are scary exxy

EVERY big HP RB that I have seen over the years has used Splitfires or a custom ignition system. For cost VS mucking about with something custom you cant go past Splitfires.

Oh well not that much lol, I think around $900 for OEM vs Splits with are $550? Cause it was "almost" double.

I think you can get OEM outta the states though cheaper. Not looked into it

(pricing my be off a little, had not paid attention to pricing for quite a while)

[33GTRV]

yeah nismoiud, i can source OEM new for approx 105 landed each which is cheap as chips. Its got nothing to do with emmisions, i just want it to work faultlessly, and not have to worry about it. As for the cost VS. Splitfires, i may be able to do something for less than half the cost of splitfires, ill let you all know later on and if it eventuates. Cheers for the input so far guys

This.

So you guys don't care about drivability? With a better coil and larger plug gap you will get a more complete burn - which means better usage of the fuel and less contaminants in your oil.

Can anyone comment on what plug gap they are running with STD coils vs torque/hp they are making? I was at the limit of my ignition system on my rb3026dett -5 32 at about 12psi (7200N /290rwkw) with .9mm gap and that was with a fairly good ignition system(the parts were obviously old but in very good condition) they were good test coils for most other cars....

[R31Nismoid]

Well @ 500rwkw, you don't have that on a 2.6 or 3ltr - you have plenty of lag though.

For me: OEM coils, 19psi 360rwkw .8 gap. Drives and idles perfectly.

If you run out of ignition @ 12psi with 290rwkw, parts were clearly past their date of expiry.

I know of another 3 cars who are 400-420rwkw with .8 and Splitfires no drama's at all.

I have brand new OEM coils plugs at 1.1mm and making 240kw at one bar. Shortly to increase boost to as much as possible with my GT3540 so hoping for better than 300awkw and will let you know if my coils aren't up to it but I'm not expecting any problems. I accept it could be different with an RB26 making 500kw at 10,000 rev/min.

Twice we agree in a week.

I have LS2 coils on mine, I made a neat bracket too out of aluminium so all the coils sit inside where the valley cover goes and I run real short 10mm leads. Go the LS coils, the LS truck coils will deliver a huge spark... you can get rid of that ignitor too. More spark than you will ever need.
