Sounds like coilpacks or spark plug - a cylinder or two isn't firing. Unburnt fuel going through the hot headers or turbo(?) is what's making the cat glow.

If it does it at idle, you can diagnose by running engine with bonnet open and pulling/replacing each coilpack individually until you find the one that makes no difference to the engine sound. Then when you find the faulty cylinder, swap it's coil pack to another cylinder and see if the problem moves to the new cylinder. If it does, then coilpack. If it doesn't, then loom or spark plug in the original cylinder will most likely be it.

twas indeed a broken coilpack :)

funny, i had just finished making up the carsales ad for it when i went out and noticed it.

could be a sign? :closedeyes:

Good stuff^ could have been much worse. Could have been a sign that you're meant to keep it but most people take a car falling apart as a sign not to lol.

Have you decided who will do mechanical and tune brah?

I'll do the mechanical, not sure where to get it tuned yet. Recommendations?

Car will be driveable off boost with the high flow fitted...might leave standard injectors / ECU in there and baby it to the tuner. Tao did recommend Trent cause of his familiarity to the turbos, said it would be easy to tune off previous maps rather than start from scratch.

Power fc Birds? If so you can change settings to suit bigger injectors/afm quite easily. Then just stay off boost on your way to the tuner

Forgot about this, never used a PFC before but if it's that easy I'll look it up / get you to show me. I know there's a reset which defaults it to a really conservative "limp mode" allowing you to baby it to a tune.

    • It says 300ZX, does that make it an Aus delivered car? Funny how back in the day I just couldn't care less about Z32's and these days I am just in love with them. Back when Nissan was into pushing the envelope. 🤣
    • Hi guys, just after some guidance with an R34 sunroof that has stopped working correctly. It still opens and closes perfectly fine, but it no longer tilts/vents up or down. As a result, the rear of the glass now sags a bit as it drops down slightly in order to retract into the roof, but now it can't pop upwards into a flush position. I’ve probed the pins on the back of the switch connector with a multimeter and it seems like both switches (for open/close and tilt/vent) still work correctly. Any ideas on what it could be, or where I should even start in terms of diagnosing? I'm sure someone's had this issue before but I haven't been able to find anything online relating to this specific issue, most of the issues are with the seals leaking or the motor failing entirely. Thanks in advance!
    • Do you have some data like fuel pressure? It's really hard to say if you're still fighting a fuel system issue at this point. Could be something weird like the FPCM dipping out.
    • Yeah in that case, pulling the dent out. Event a very slight dent can create a lot of work filler-wise and there is a strong chance the panel won't be the factory shape when you are done (as the dent will result in a new high point created somewhere, then everything is brought up to that new high point... but the panel shouldn't be that high if that makes sense).  So you've filled and primed the panel and it is flat, why would you go back and remove the primer and add more filler? 
    • Something else I have been faffing with while the car was off the road is making the AC work. Assuming the car isn't at a thermal limit the idea of having AC while waiting in line to go on track sounds delightful. I have actually been lugging around the weight of the entire system since 2018 when the RB25NEO went in without it working at all.  The main reason was in the first few events before I got around to re-gassing it the rubber hose that runs under the manifold had the factory heat wrap/sleeve fail resulting in this: ~2 years ago I purchased a complete used R32 AC line set but when I finally went to install it the line i needed was different where the expansion section is I found a local place that was able to replace the rubber section and re-crimp. They also added some modern heat sleeve to the hose Tight fit but fingers crossed this is the last physical piece of the puzzle needed
