Engine Cutting Out. Not Overboost.

Ok so ive got a problem with my r33 gtst. While driving along the motor will randomly cut out. It feels like the petrol is getting cut off because if I roll for a couple of seconds with the clutch out it restarts. So I changed the fuel pump (bastard job) for a high flow one and put a new fuel filter in. Still doing the same thing. Any other suggestions?

At first it only cut out above 3000rmp when coming on boost, checked all the vacuum lines etc, but then it started doing it under boost. Now it will do it under boost and it started cutting out afer a few minutes just sitting idling. Thats what made me think fuel.

Looks like I might have found the problem. While trying to jump start the car it threw a big spark across the fuel rail from the back of the injectors. Now I just have to isolate it.

Well that didn't work. :-( grrrrr. isolated the arcing and fixed the wiring there but the car is still cutting out after 2-3 minutes at idle. Can't even drive it to the mechanics to let them have a look at it. Running out of ideas. Is there anywhere else that could be blocking the line or something electrical that could be doing this? After cutting out I can't restart the motor straight away. It just keeps cranking over. But if I leave it for a couple of minutes it will re start.

      I am currently going this route. I am curious how much horse power you put behind the cut bell housing? Collins was telling me I am going to crack it and bluh bluh bluh. Because I didn’t buy the custom fly wheel from him. I am looking for somewhere around like 500 hp

      Thanks @PranK for the updated member status, much appreciated! 👍🏼 Now, about those pics… Unfortunately I could only find ones that I took in the dark. I was soon to discover that underneath it wasn’t in the best shape, but it was mine and that’s all I cared about at the time 😆

      A little PU bush story

      By GTSBoy · Posted

      Oh, and only having done this task yesterday, I've now driven the car ~60km since, and while it is hard to avoid placebo effect and confirmation bias, I reckon that some annoyances I had with the way the car has been behaving have improved. Which....kinda makes sense, I guess. If the bushes were really stiff and resisting rotation, they would have been contributing to the effective wheel rate. And if it was more so on one side (which it was, because one side was worse than the other) then.... you might imagine that the additional rate would be asymmetric, and potentially even different between compression and rebound. And so... the car has been twitchy at higher speeds - like freeway on ramps. It really shouldn't be. The wheel alignment is good and there are no (other) known problems elsewhere in the suspension. But at 90-100 on a long sweeping ramp, tiny steering wheel motions would make it feel like it wanted to rear steer. Quite nervous. At lower speeds it would heave about in a manner that it didn't use to. Didn't want to put power down, etc etc. Now...seems to behave better. Am going to have to concentrate on the various corners where it has exhibited weirdness, on the rare occasions when I can get a decent run at them without Methanial getting in the way in his D-Max/Ranger/LDV Van/etc.
