About to change my coilpacks on my 96 R33 GTST to try and get rid of the misfire at high revs on boost problem (5-7k for me.. higher than most).

Everyone talks about the Splitfire brand of packs. Looks like they would cost about $550ish delivered. A guy at Autobarn told me coilpacks can be bought for the Skyline that would be $250 total. My question is: are the Splitfires so much better in any respect? e.g. design, or longevity, or performance? On the thread about doing home-grown fixes:

it looks like ppl are filling particular areas on the coilpacks with sealants. I'm wondering if the Splitfires have particularly better design than the stock coils and if that is what ur paying for. For obvious reasons, I dont want to change my stock coilpacks for new ones that aren't up to snuff or "el cheapo" dodgy 5h1t. So why does everyone rave about Splitfires? What else can they be compared to. I'm willing to pay the 550 or so, but only if they are the best, or very near to. The main thing is, I want to eliminate the coils 100% as the cause of the misfire.

And another thing, out of all the ppl who had the misfire problem and replaced the coilpacks to fix it, how many found it actually fixed it (COMPLETELY)? And how many were ripping their hair out after cos it wasn't the cause? Nearly poll worthy, but it wouldn't be very useful really... just to see the "odds" of new coilpacks fixing ur car hahah But I'm getting really annoyed now with farting around with the car instead of just driving it! I'm gonna fix this car if it kills me, sends me broke, or drives me insane! :P

People rave because they work and broken old stock coils don't. They are pretty much the only ones apart from Nissan genuine and they are cheaper.

I don't know what you get for $250 - maybe 2 second hand coil packs...

If you can fix them with the suggestions from that thread then that's great but if not they need replacing.

You can run a non-protruding electrode plug similar to the race plugs we use.....but........they fuel up very easily and dont like to not be run without a bit off boost up their bum. Easy fix.....run splitfires......we do on the street and have no dramas.

the below link is for what i fitted to my RB25 and I have eleiminated any missfires and it cost $300. in total $250 for coils and $50 for leads

    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
