Got a misfire. It's most noticeable in 2nd under full throttle and it starts misfiring at about 5500rpm. In 4th at about 5000 rpm full throttle. I'm guessing it's coilpacks. In all other regards she's running fine. I'm sure other gears too but these are the stand out occasions.

Is this likely?

Cheers.

ANother vote for splitfires, had the same thing happen to mine

PS, hows your gearbox? You got the one from Sydney yeah?

Sounds like the coils then.....I think they're now $625ish. Nissan wants $1,200....

Gearbox is OK. Bit of bearing noise and 2nd synchro could be better. Long way better than my old one, but I'm still looking for the gearbox holy grail.

Id check to make sure 110% though before buying.

Simply swap over with someone's who you know works.

You can use mine if you want, they are near new splitfires.

A kind offer. You're quite right as I'm only guessing it's the CPs. Drop me a PM with your number and I'll call to arrange?

Cheers.

umm instead of buying new coil packs why not just repair them? and when you have cash get splitfires then.

when i had my 33 repaired it then and never had a problem afterwards. mates GTR33 is putting out 270 atw and was getting misfires like you on full woot did a repair and all is well

my current car R34 GTT 240 rwkw also had misfire and 3 hours to repair and its as good as new.

all you need to do is take it out clean it all up then put a nice thick coat of clear nail polish. i did 3 thick coats on mine and took about 3 hours from taking it all out to going for a test drive.

all it is one or more of the coil packs have a fine fine hair line crack on them so on fool woot the sparks archs out of it causing it to misfire.

its very easy to fix and is a cheap alternative while saving up for splitfires.

Thanks for your input Ash but I think I'll go for a more robust and permanent solution. The CPs are now 18 years old and I can't be fugged going on my next all too rare drive to miss out on my fun because my....erm....wife's nail varnish didn't do the job. Glad your trick has worked for you though.

      Duncan's V37.......race car?

      By MBS206 · Posted

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      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

      Duncan's V37.......race car?

      By Duncan · Posted

      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.
