Hey guys, I run a set of the yellow jacket coil packs that Performance Wise offers. To set the scene, picture an RB30 block, built to "nissan spec" (Now, I use this term loosely, as the whole motor

Not true for Yellow Jackets. We tested the YJs thoroughly before releasing them to the market. Not just in the factory, but on the street and the track, in real life circumstances. Im still in contact

This is an outdated statement as everything is made in China these days. My Yellow Jackets are made in china and I oversee QC and work closely with my factory and now, 5 years later, and over 2000 se

coils are coils, but you would need to stuff around mounting them, they would not have bolt in direct fire ones like jjr/splitfire/owm

coils are denfinately not all the same. the aftermarket stuff has really come a long way. the nissan std coils r quite good, but imo there is a whole range on very powerful coils out there that would b better than std (and prob cost around the same sort of $$). example, i changed to MSD coils from stock ones in my V6 commodore and dropped from 14.5 to 14.02 with just the coils and a small adjustment to the tune in the last 1000rpm (merely to correct a/f ratio). making brackets isnt that envoled either.

Well i have some issues with Splitfires, the first set died 6 montch after purchase 4 coils startred to die, and it looks like that migh be the case again, either way my Central 20 ECU and splitfires don't like a gap above .8 mm at 15 psi

The issue is clearly with the ecu/tuner combination.

Have your tuner pull his finger out of his bottom and check the coils dwell vs rpm has been setup correctly.

If its not it will either provide a weak spark or overheat and kill the coils quickly.

My bets are on the later.

does that mean if i put aftermarket coilpacks in i will have to get a re tune. you cant just put these in?

are you sure your central 20 ecu supports sequential ingition and is not operating in batch mode or something ?

out of the 50-60 or so splitfires we have supplied in the last 12 months or so we have NEVER had a single one fail

out of interest OEM coils are 180 each trade price and the coil pack loom (engine sub harness) is about 200$

standard ecu

mods - zorst, FMIC, pod

only mod i added since splitfires was manual boost controller set to 10psi, 200rwkw

and i don't thrash my car, only done 5000km since coils changed to the splitfires

ok as you didn't fit the splitfires your self I'm assuming your guessing that the coil packs have died.

In other words you haven't pulled the coil packs out yourself, inspected them did the usual trouble shooting one does before they come to the conclusion that something has died. :ermm:

What brought you to that conclusion?

If its started popping it can be maaaaaaaaaany things. :D

The AFR's are too rich.

Plugs need regapping.

Plugs need replacing.

Ignition has crapped its self (if its a s1).

So fingers crossed its something silly. :D

yes i am guessing so probably shouldn't assume :D

but the car makes excatly the same noise as when my OEM coils had died.

last week it started stuttering/shaking at idle. now at 4000rpm onwards it pops to the bs

took it to my other local mechanic and he had a quick check of the plugs/sensors/af meter couldn't find anything obviously wrong

plugs were replaced same time as splitfires installed

don't have an a/f ratio gauge

yes, hope hope it's something basic. otherwise hope hope it's still covered under warranty. i've still got the receipt from the mechanic.

anyone know what the warranty is on splitfires, someone please say 12 months?

found these coil packs on ebay. they are called super spark coils and they say that they give you 10% more spark and they are to suit RB20, RB25 and RB26. at $499 what do you reckon? has anyone else heard or know of anyone using these.

they look to me to be similar looking to the JJR packs

They are exactly the same as JJR, only $100 dearer per set.

      R35 GT-R production ends after 18 years

      By Rezz · Posted

      Order for the 2025 model R35 GT-R were accepted from 3rd March and 26th August the last order rolled off the production line at the Tochigi plant. Concerning the R35 GT-R replacement, current Nissan CEO Ivan Espinosa said "Nothing has been decided about the GT-R at this time, but we are well aware that everyone is waiting. The GT-R will evolve and reappear in the future. Please be patient until that day comes." Nissan has a lot of issues with management and finances so take Espinosa's words with a big grain of salt. From what discussions I've had and read about here in Japan, not a lot of people are confident about Nissan's future, let alone the next GT-R.

      R34 25GT Engine Light 21

      By MBS206 · Posted

      21 is explicitly the coils detected as the issue. Is it guaranteed the actual issue? No. Just the ECU thinks it is. When you say rattling, describe it better, get an audio clip as best you can if possible.

      By CF.Panda · Posted

      Yea got me coppers. Bad news is I just put them in and the car still has the light and shakes. I also noticed I hear like rattling coming from the exhaust piping right under me. Does 21 also have a possibility of being O2 sensors?   So, coil packs are good, the harness is good, the MAF is working, and obviously the spark plugs just replaced and working.

      RB25DE NEO with Haltech ECU

      By MBS206 · Posted

      Make sure you drop the GTT base tune back in, and set your injectors again, this will remove anything playing up with it you may have removed. Possibly lean there as it's normally a fast transient going THROUGH atmospheric pressure, and a turbo motor would then quickly go richer as boost builds. The only worry you MIGHT have is ignition timing, as the DE is higher compression than the DET from memory. But again, you're not in boost, so the DE motor will be a lot more forgiving at atmospheric.   Get Murray, Kinkstahs, and Johnny's input on tuning haltechs, those guys have played with tuning enough in the past to be able to help now you're past the trouble shooting stage of the MAP issue
