Which silicone do I use to put on my coil packs to help the missfire on boost? There's a lot of different kinds, like the gasket stuff and the spray silicone, but can someone give me a picture or the name brand and which type of which one to use please? Also, is silicone the best thing to use, because I have seen posts about people using clean nail polish and heatwrap and stuff. I HAVE SEARCHED TOO!

Thanks,

Mike

Selleys 401 is the one i used. Its industrial grade high temp silicone, used as an insulator, amongst other things. You can get it at bunnings.

It's probably just as important to clean the contacts on your coils, where the spring sits.

The last thing i tried was stretching each spring about 8mm longer, to make a better connection with the spark plug. I havent had a misfire since, but then the weather hasnt been freezing cold, so it may be due to that.

Thanks a lot.

no that wont work. that's more like a lubricant. get the 401. it's only $10.

Okay, the problem is that I live in USA and we don't have bunnings. Do you know of any other brands? Or any other stores I Can get it at? I don't think USA has shellys

what is the silicone supposed to be used for? ie, painting, flooring, ect? Is it like the caulking stuff?

it's used to seal glass on oven doors, and also used as an industrial electrical insulator.

not sure of an equivalent product, but there would be something.

here's the selleys 401. it's the only pic i could find

here are mine

seal the whole underside of the coil, up to the bracket. leave the stem uncoated, as you need to fit the rubber boot over that. also make sure you clean those contacts. u can see mine are shiny gold. they were a dull grey when i started.

awesome. thank's a lot.

no worries man.

have you made sure your missfire isnt caused by your spark plugs? 0.8mm gap is highly recommended, although nissan specify 1.1mm

and many people have found the copper plugs to be better than the platinums/iridiums, that are also recommended.

    • Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?  
    • roof rail delete used to be a thing, they were made locally for a while too
    • 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.
