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.

    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
    • I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things
    • I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt
