Aftermarket Coilpacks

[Turbo2.6L]

Chasing some info on the following 2 brands of Coil Packs:

Splitfire
http://www.nengun.com/splitfire/super-direct-di-ignition-system

Yellow Jackets
http://www.performance-wise.com/userimages/procart28.htm

Will be going on a GTR running E85 & aiming for 600+awhp with 25+psi boost. Standard coilpacks have limited the current boost levels to 1.5BAR due to spark blowing out at higher levels, so require something new asap. Prefer firsthand knowledge if possible...
I'm not worried that the Splitfires cost a little more, but would rather buy a set based on an informed decision rather than relying on prices as a measure of performance.

if you don't mind spending the extra cash i would have a look at Okada Project Plasma Direct
http://www.okadaprojects.com/usa/products.htm

Or else just go the Splitfires and if you aren't getting enough spark just buy a HKS Twin spark (personally would just try the HKS Twin spark with std coilpacks if yours are still in good condition)

[Turbo2.6L]

Seen the Okada Projects Plasma kit after i posted this thread... Have you used one before?
Also, can't seem to find anything on the HKS Twin Spark in conjunction with a GTR?? Are they compatible? My OEM Coilpacks are perfect as far as i can tell, no problems with spark apart from when using high boost levels as posted above.

[c.rusli]

Dont bother with spark booster,
most of the spark booster will eat your coilpack in a year or so of using it.

as above, go OKADA, or M&W coil pack system .

sorry my mistake its HKS TWIN POWER
http://www.hks-power.co.jp/products/electronics/tenka/twin.html

Hks make the kit the bolt onto the std coilpack harness

i have never personally used the Okada, but when i was looking to upgrade my coilpack on the gtr, i did alot of reading. Most people on SAU with high hp GTR say that stock coilpack with the hks unit is a good option, Splitfire seems to work well aswell but some had reported them becoming fked after few years. Okada gear seems to only be running in big budget builds so there wasn't that much info but the few things i could find everyone rave about them

[Turbo2.6L]

Ok cheers, will look into the Okada setup a little further then!

[Lonewolf]

used yellow jackets on my RB20 when it started to misfire
were 1/2 the price of splitfires and with a longer warranty

worked fine, but obviously a different application to yours

Pretty sure Brand new OEM are the best coilpacks you can buy, somebody correct me if im wrong.

correct, hence why i mention using the hks twin power if his spark isn't enough for the boost! however everything i read about these Okada coils are makes me think they are better however i have never used them so can only go on second hand information.

[Alt_F4]

A decent CDI system is what is needed, and wouldn't be much more than what your looking at spending with okadas or splitfire+ hks twin spark.
I think GTRgav is running cdi on his 32R now with e85 at power levels your aiming at, might be the man to ask.

doesnt he run the hks twin power?

[Turbo2.6L]

Ok, will wait for more info before purchasing anything then. Too many conflicting stories! Haha

[Alt_F4]

Changed earlier in the year, he's running a M&W setup, specific info on SAU in FI section somewhere.

[Turbo2.6L]

Best place to buy M&W CDI unit? Direct from M&W, or is there a re-seller that may look after me in WA??

[c.rusli]

i got my M&W from over east, from evo forum.

Looks like M&W CDI is the go then. Cheers fellas :D

[SimonR32]

I arguil a lot in that thread haha

I've got Yellow Jackets in my RB25 running fairly decent boost and power and they are fine, Splitfires are possibly better but more expensive, OEM are also great when fresh and new but even more expensive!

Also check the harness because they get old and cause issues :)

[Tocchi]

Dean, if you are looking at the M&W Prodrag6 system, prepare for about $1400 from M&W :O

[Turbo2.6L]

M&W system with coils, control box, harness, bracket, plugs etc is $2250. Not bad considering Splitfires + twin spark + new plugs would run close to $1500...

[Azrian]

plus a new gearbox once its retuned and your looking at $4000+ haha

[Turbo2.6L]

Only if you drive it again, which wont be happening pingpingpingping!

[carlos spicy wener]

splitfires are junk, i wouldn't bother. they start to break down with high boost settings.

as OZZ said, OEM coil packs are the best you can get.

or

you can run a coil for each cylinder like i have, and if you are feeling fruity you can change over the igniter to something like a micro tech x6 or similar, which will increase your spark dwell time.
a setup like this would be no dearer than a set of splitfires, infact it might even be cheaper.

all you need is 6x bosch HEC715 coils, and a set of custom length ignition leads.
then you wire them into the coilpack harness.

*not my engine bay, just an example.

Sorry - just saw this thread.

By changing to CDI over Splitfires and HKS Twinpower, I picked up around 30 hp in the mid range.

This is the kit:

If you are going E85, a big fat CDI spark lets you add much more fuel and timing.

Drop me a PM if you want to come and have a look at the setup.

[Turbo2.6L]

Re-visiting this issue as my splitfires or ignitor have shit the tin it seems. After a bit more research, it seems LS2 coils are the go (configured in a similar fashion to 2 posts above, less the microtech X6) if i don't want to spend $3k on CDI... But my question is, can it be run off a PFC ecu or is the ecu trigger signal not correct? Need a 0 - 5V positive signal apparently, stock ecu is 12V but unsure on PFC??

[Brett_J]

Message this mad dog, he was running some Marine coil setup in his big HP GTR.

[Skitzo]

For what it's worth. Carlos Spicey Weiner is running PowerFC.

[Turbo2.6L]

What signal would they require & what dwell times on them Luke? LS2 coils are suited if they can be run from PFC computer, but these being a COP setup may be the better option.

[-Luke-]

Was trolling Dean. They are coils for 3600kw Cat CNG Power Generation/Marine Engines

[Turbo2.6L]

So good spark. Still keen :p

[-Luke-]

Oh yeah, Not sure the 600hp from an RB would be enough to drive the coils!

You pay & i'll go CDI. I'm broke & mortgages last 20 years, 5 years into 1 & 12 months into second means i'm fingered :p Hahahaha

Get the new wife to buy it for you as a end of financial year present.

[Turbo2.6L]

No. Chance.

[cplagz]

ACDelco D585 coilpacks. Pretty sure they are the strongest spark on the market.

[jez321]

Figured id post here instead of starting a new thread. Basicly looking at upgradeing the coilpacks in the Gtr because i think they are starting to cause some issues and the engine setup is getting bigger. What are pepoles opinions on useing ls1 coils on a rb26 vs splitfires ect and has anyone done this?

Car will be tuned on 98 with a gtx35 but i want to be able to support e85 also if i change my mind later
Thanks in advance

[Alt_F4]

Splitfires are drop in and are great to certain degree.
LSx coils overhaul the ignition system cheaply (comparatively) for a better result, but are more fucking about

[180SXTCY]

the marine coils will be mercury coils.

seen them.in action with a 500r autronic cdi punching some big sparks.

Splitfires.

Just an FYI SimonR32 and myself are making ~600rwhp on E85 with no issues.

Ahh cool that may be the way to go definatly looks like the easyer option
