first of all, does it lose power from straight away, or when it hits boost, and does the car run rough when cold and get better once warmed up?

need some more info mate

also, does ur boost guage still read what it used to read? is it still boosting properly?

Yeh I was going to say check the boost. Might want to leave it to the pros though. Send it to someone who's probably going to be able to take a quick look at it then fix it.

Edit: Clutch could be another if the revs seem fine but the car pulls nowhere.

Car is loosing the power straight away ..it still boots up but its laging .. no rough idle can put a cup of tea on the motor with spilling a drop.. have taken it in to some now .. Lets see what he can come up with .. most likely it will be something simple ..

power loss is straight away .. it just doesnt want to pull.. It uesed to fly but now it seems to take for ever to power up now if i run tomuch boost in it ..like 12psi or as soon as it reaches 8psi it just hit the defender and cuts out

    • 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
