Went to gippsland yesterday from frankston, didnt miss a beat for the whole 340k's, even got 10.5ltrs/100k's, this morning i started it and it run fine, decided to work on it instaed of going to spend money so i turned it off, been having problems since i installed my lcd nismo cluster, it says im doing half the speed im actually doing so i thought i would put the old one back in and see if that fixed it, before i put the facia back on i took it for a quick spin, as soon as i started it i relised something was wrong, it idled like a pig and every time you reved it there was a cloud of black smoke, took it for a quick spin after stalling 3 times trying to get it out of the drive way, stalled a couple of more times whilst slowing for speed humps and still putting out black smoke.

Question is what is behind the cluster that could cause this to happen?

Took out the plugs and attached pics, they look bad but im assuming it is more from un burnt fuel.

How do i check my coils and ignitor to make sure they are working properly?

yep swapped them back and it still has the same problem, i then removed it all together and still the same problem, cleaned everything up (couldnt get new spark plugs today so i just put the old ones back in) and put it back together, run about 90% good untill i touched the accelerator then it went back to shit, will get new plugs tomorrow and see if its just that, im assuming its possibly igniter and/or coil packs but would like some more info on testing before i replace them.

Worked out how to do it, code comes up as 2 long flashes and one short one which i believe is 21?

Now i just have to figure out what it means, all the threads i find does not have a definate cause of a 21 fault code, seems to be a cas, igniter or coil pack problem, any one know which one is the best to start with?

Just replaced the cas it it would not start at all, sounds like its trying to kick on a couple of cylinders but just wont turn start, put the old one back on that the engine would start with but run like shyte and now it wont start with that one either.

Any one have any ideas, gotta be someone out there with an idea??

I have since gotten the car to start, i have replaced the afm, coil paks and ecu with no change, still trying to get a hold of an igniter.

Any suggestions would be appreciated.

Does anyone know how to read fault codes, when i first did it the fault code came up as 2 long flash's and one short one, i assumed this meant 21, after looking at the manual the way they describe it is that it means 12, have attached a page from the manual.

i would check your afm, swap it out if you can or even just make sure its plugged in. Check all the wires are fine where they go into the plug, sometimes they ge bent or stretched to much and you need to solder them in

That was one of the first things i changed, played around with the wires and there was no change, unplugged it, surged for a second or so and died, woud not start again, plugged it back in and it fired up but still ran like shit.

no, fuses didnt cross my mind, what one would cause these sorts of troubles?

Just bought a fuel pressure gauge to see if the reg is screwed, any idea what the fuel rail pressure should be?

Got the fuel pressure gauge in, on idle it sits at 38psi when reving goes to around 44psi, videobelow shows the gauge and the smoke it is putting out.

i dont know if this would help or not but when one of my cooler pipes came off thats how my car ran but it wouldnt idle at all it would just die. it looks like car is geting fuel so thats fine. just check all the fuse. there should be a bunch next to the accelerator pedal and the box in the engine bay. check it all.

      I know mentally you're set on the ATS clutch but honestly I'm a big fan of the Nismo Super Coppermix Twin. It's much cheaper and in some ways I think it's a better design for a street/circuit car.

      Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.

      Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.

      It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!

      Nominally yes but I’m not really at that stage yet. Outsourcing to Japan is also a relatively good deal at the moment because their currency has devalued much more against the USD.  You would assume this but a lot has changed from the pandemic. Mechanics are in short supply and demand for fixing old cars has gone up from the cost of new cars. 250-300 USD/hr is not an unusual shop labor rate in California and you’re paying that regardless of whether the guy is competent or not. Coworkers have been quoted 3000 USD for a water pump and thermostat at a dealer on an N54. Oil changes went from ~75 USD to 150 on fairly normal cars like Civics. The cost of the oil and filter hasn’t even kept up with inflation.
