i was hoping that someone can give me some feedback as what is good brand for replacement coil packs- i have ocational hesitation on take off and i have swapped them with second hand OEM ones, but really i'm pretty sure i will buy new ones shortly as this is really common on all skylines!

Apart from SPITFIRE is there any other brands that are more reasonably priced?

I mean when i look at my application i think that spitfire may to over kill for my purpose. I will look into it and make a decision shortly.

The best feedback is from user rather than saleman/ company, so i value this greatly. Thank you

^^ I have Splitfires and they are great!

I have seen Yellow Jackets for about $370 + and Splitfires are about $480 +

Ppl seem to think Yellow Jackets are good, if you don't want to spend as much on Splitfire, Yellow Jacks seem to be a good option.

When I was looking at coils I was tossing up between the three major brands. Splitfires, Yellow Jackets and the Just Jap coils all had much the same mix of reviews. I.e. great product, sporadic cases of people receiving faulty items but in all cases were replaced by the manufacturer. I reckon you'll be happy with whichever one you go for.

What's important to me is after sales support. I know Yellow Jackets back their product because after I posted an honest review of them on the forums (including report of a minor installation issue I had with one of the brackets on a coil) one of the Yellow Jackets guys came on SAU and queried me about it, offering to replace etc.

got yellow jackets for myself. fixed my misfiring i had for 2 years. i tried heaps of things including swapping 2nd hand coils, taping them up with high temp tape, 0.8mm gap plugs, rewiring my ignition power supply with high current relays and changing cas. i now run 1.1mm gap iridiums no probs. although i do remember having to file the bracket or something coz the yellow jackets were slightly bigger.

sorry to bring up such an old thread but can someone confirm this?

are yellow jackets a straight fit? ie , nothing required to replace them?

They are a straight fit, no modification required. Just make sure, if you have an R33 GTS-T, that you identify whether you are series 1 or series 2 - coilpacks differ between these two models.

Most of them are probably made in the same Chinese factory and will work fine, but I have used YJs in 260-350rwkw cars with no issue. Even done back to back with Splitfires - the differences were negligible and some areas of the dyno graph were in the favour of YJs.

Plus Paul (Performance Wise) is a great guy, if you ever have issues he looks after you.

as matt said, the brand probably means zero

any brand new coil pack will perform better than 15+ yrd old coilpacks

oem, splitfire, yellow jacket

i put splitfires in my ecr33 when it had misfire on boost, fixed it no problems

I got a set of YJs from Performance Wise and about two weeks in two of them died. I contacted Paul (from performance wise) sent him some pics of them and he sent me out a full set of replacements within a couple days. The second set have performed flawlessly for the past year.

I recommend them and recommend getting them through Performance Wise. Yes, I had an issue, but Paul was great getting it sorted very quickly and without me having to take my car off the road (I sent him the defective ones after he sent out the replacements).

      Need AC Compressor for R32

      By Zabuza · Posted

      Ok glad you clarified on the frenchy’s options , I was worried about if my oem hoses would fit the new compressor or not if I just bought the bracket/compressor kit ,  didn’t realize they also sold a larger full conversion kit. Hmm may just go oem in that case then to make it easy only because I plan to sell this car to upgrade to a 32 GTR or 34 GTT.

      Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4

      Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went?

      V36 2008 Coupe Wiring Differences with Android Screen

      By sausagepianist · Posted

      Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was ￡307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell.

      As above, you did refill the coolant and burp the system before running it again didn't you?
