check that ur wastegate isnt stuk open if its and internal type. just pull the vaccum line off the actuator and see wat it does aswell. and ud hear if u had a major boost leak bcuz ud hear a massive rush of air and ur car would run like shit due to the amount of air ur afm is seeing pass through it and wat is actually making it to the engine wont comply with the injection duty that its givin hence it will be overfueling etc. and or u shit ur exhaust wheels lol

You took all the VAC lines off the BOV...

Did you block the BOV up?

If not, i wouldnt be surprised if its being blown open

Id check the piping/clamps again also.

If all you've changed is piping and BOV setup, then your likely to find its something to do with that.

Just because something 'looks' attached piping wise, doesnt mean its holding under pressure, and could be behind the sie that you can see etc

Lumpy idle is a sign of a leak to begin with.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      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.
