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.

    • Oh, also, forgot to add these photos I believe.
    • Thought i'd update on this. I was able to get in contact with Craig Lieberman and later on Darryl Alison (owner of Kaizo Industries). Darryl was able to help me verify that my car was in fact one of theirs and is helping me find more info on mine !
    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
