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.

    • Ok thanks..that was my second question if i can somehow bypass this even with Nistune(that is all i have right now...aparat from stock ECU. So with some aftemarket it can by "bypassed" or make it work?  I know there is Link or Haltech (mainly used). We have ECUmaster here so i will gather some info about it.
    • Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.
    • Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that
    • I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.
    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
