Hello,

I was wondering what everyone's opinion is on what coil packs are the best to use on an rb20det. My r32 had little misfires since the day i bought it. One of my  yellow jacket coilpacks failed a while back and melted through the housing. After i had replaced the failed coilpack it was good for a short while untill it started having misfires again. (Still only happening on idle). I checked my wiring harness and noticed that the signal wire to the failed coilpack was damaged so i replaces the damaged cable. But the misfires still remained.

I currently have yellow jacket coils installed and have a new set of splitfire dis 001 coils and a new wiring loom to hook up to the oem ignitor but i really would like to delete the ignitor. I have 2 options/idea's

Option 1

I tought about selling my new splitfire dis 001 coils and order a new set for an r34 skyline (smart coils) in combination with a wiring specialties harness to hook it all up without ignitor.

Option 2 

I have seen some post of people using ngk audi r8 coils on their rb's and opposed to the r34 coils these are way cheaper (over 300 euro's cheaper). And ordering them is alot easier because i can just get them from my local autoparts store. Now the wiring harness is my issue i looked for a long time online and i couldnt find a harness for an rb20det to fit these r8 coils to so i would propably have to make one myself or get one made. 

My final question is what your opinions are on this and what would be my best option.

Sorry for my english i did my best

You have already discovered that Yellow Jackets are no good.

Stock Nissan or Splitfires are recommended but I believe the R8 coils will also work fine. Sorry can't help with the wiring - try googling... I am sure there are some guides somewhere.

I am assuming you have some kind of aftermarket ecu or a Nistine chip

Still have stock ecu and i would like to go g4 link in the future or ecu master

Option 1 is the correct thing to do. It is extremely easy to convert to smart coils from RB25 S2.

Buy a new coilpack harness to suit RB25 S2 as well. Stock ones are usually junk by this time.

Hey guys, 

I'm looking installing a Haltech on my RB20DET series 1 and as part of that i'm installing 

RB25 Series 2 coils to remove the ignitor. Does anyone know if the standard mounting 

bracket for the coils will work? 

Thanks in advance. 

I'm using "nasty old coils" because I've already ordered my new loom with series 2 smart coil connector sub loom, and I'm running a pretty much stock RB20det which will be lucky to make 180kw. I think the coils will be ok for my application. 

 

Thanks for the feedback about the bracket. When my new coils arrive I'll have a loom and machine a new bracket up. 

So sell sub loom for coils and go to

If only 180kw why are you even worried about deleting the ignitor when ignitor coils can handle heaps, like 400kw+. Sell sub loom, go to R35 kit if wanting the ignitor delete solution.

Makes no sense to delete ignitor then run stock / splitfire S2 coils for the cost -  complete waste of time really.

I already have the answer for the question I asked. but thanks for your opinion. 

 

Just trying to reinforce how much of a quantum leap the 35 coils are are over what your proposing doing, compared to not changing the stock coil setup at all. If you don't already own the S2 coilpacks yet you could still change without a big cost difference👍

I totally agree with you, I have done a bit of research and by far they are a better option.

But yeah, I already have the coils ordered and the loom and ECU is also on its way with plugs for the S2 coils. The engine is a Series 1 RB20 so nothing has really been straightforward. It wasn't just for the purpose of an ignitor delete.

    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
