Hi every body,i am new to this forum and from what i read over the past weeks i am sure some one will be able to assist me.

I am on here on behalf of my son and i am hoping you might be able to help me. He bought a skyline r33 with the rb 25det series 2 engine about 18 months ago, every thing was going fine till about 6months ago when he started to get a missfire. We found that the original coil packs were shorting out. I bought a new set of super spark coil packs and had the mechanic replace them. the car ran fine for a week when all of a sudden it started to missfire again and i thought it couldn't possibly be a ciol pack problem so this time i took to a high performace tune up specialist specilizing in skylines. After putting on the dyno and checking the entire system he found one of the new coil packs was not firing and we replaced it with a second hand nissan one and again every thing was ok. The faulty pack was replaced under warranty and we took out the second hand coil pack and replaced it with the new super spark pack. Two monthes down the road and would you believe it the same problem again, this time we took to a high performance specilist in melbourne who found 2 coil packs not firing. Had to pay for a genuine nissan coil pack just to get the car on the road, the car was once again running fine and after complaining to super spark supliers had the whole set replaced under warranty. I have now replaced all 6 coil packs again and 1 month later one of them has already faileddevil.gif

my son's car is stock standard apart from the front mount intercooler it has been checked by 3 different specialists and they have found no other problems, the coil pack loom is fine and has checked and it runs at standard boost. The thing is the problem has deffenetly been the coil packs but i realy can't see how all these coil packs can be faulty and fail in such a short time. Is there anything that could cause the coil packs to fail? His ECU is standard as far as we know and the mechanics do not seem to think it has been tampered with. Please help if you can. I can only tell you what the mechanics told me so i don't know how compitent they are as i think that there has to be something causing the coils to die, so fer it has been cylinders 1-2 and 6. I am thinking of taking to a place called "Just Jap Auto Imports". Does anyone know of a good place to take the car? I have been told that there could be an electrical problem can some one please shed some light on the subject ? I am a pensioner and can't afford paying when they don't find the fault and just tell me that the coils are faulty. I don't mind paying if they find the problem and not take the easy way out and surely we can't be so unlucky to cop all these faulty coils. I now this is a long thred for a new commer and i am sorry to be a bother but please can some one help. Thanks Paulworship.gif

Hi Paul,

Just Jap ar great. Coilpacks are notorius on the 25's. Shell out (there should be a group buy on here) and get a set of splitfires. They do have the habit of all failing around the same time.

Second hand is just not worth spending money on.

Cheers,

Ken

Hi every one, Thanks for your quick replies and feedback i just want to say that i will take every suggestion very seriously and hopfully find the problem. I made a mistake with name in my previous message about where i am thinking of taking the car, the proper name is "Advanced Jap Auto Imports" in tottenham vic. so please let me know what you think. As for the coil packs they were all brand new and they are the Supa Spark brand. Thanks Paul :happy:

Thanks for you input the coil packs were brand new and the brand were Supa Spark, if i changed over to splitfires do you think they would overcome the problem? I agree that second hand would be a wast of time. Tahnks Paul

    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
