I suspect a bad spark, causing rough idle so looking at changing out my coil packs.

Anyone have any feedback on the yellow jackets ?

how rough idle you get?

I'm not sure they are specifically for vq25. They are marketed as being suitable for a variety of models. I remember someone on sau using them on a m35 but can't remember what the exact feedback was. Maybe try doing a search or hopefully said member can chime in. Personally I would be going OEM but I would also want to make sure it is the coilpacks that are the issue b4 forking out the $ and potentially being disappointed and wasting some hard earnt. My 2c. Good luck.

Those yellow jackets are designed for NA VQ's

I bought them and continually had problems with them.

OEM coil packs are the best for VQ25DET.

The oem turbo coil pack has a different part number to the NA coil pack.

Yellowjacket copied splitfires coil pack which was designed for NA 350Z/V35 etc.

They are the same fitment and do work, but there is a noticable power loss as the coil packs begin to degrade after a VERY short amount of time. They end up partially firing and then not firing at all. This was my experience with them anyway and I went through 2 sets of them over 4 months.

    • I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps  
    • According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car. 
    • It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
