I assume your running an aftermarket turbo on the standard ecu. That is your problem.

Yes, but thats the stock turbo.

Just because one car "seems" fine, doesnt mean the next one will be :thumbsup:

If you have detonation its generally

*The tune is crap (in your case, its not even better than factory which is a major issue)

*Injectors not upto the task

*Fuel pump, could be on its way out

Although, having changed the turbo. I dont know why you wouldnt have installed a dump pipe aswell, thats another key mod

      Oil pan for RB25DET NEO Stagea "version"

      By Dose Pipe Sutututu · Posted

      Not at all, pure street use, touge, even drag strip and you'll be fine   There's a larger version of it too, however would be overkill for your application. If you do plan on using that sump, might as well fit a headdrain/crank case vent to help alleviate crank case pressure. Your mechanic will also notice you cannot re-use the AWD windage trays on the motor too, as it fouls with the AWD -> RWD sump. However given your usage, you'll be fine.

      @GTSBoy yeah but the MAIN problem is that "you" guys may know that but i/my mechanic did not. I literally spend hours to find differences between Stagea and Skyline engine (even here) and found kinda "nothing" Yeah one guy mentioned that the block is larger/wider but nothing about the oil pan. Of course AWD has different one but "everybody" says...yeah just slap RWD pan... and the parts number for my N/A engine and NEO DET were the same so iam using one from my old engine. And of course being in EU/Czech many of the sites did not even show(i need VPN to be here)... @MBS206NO it is not my channel and not my video. Dont even know the guy. I just post this as a reference cuz i have the same problem. As i said you guys in AU/NZD may know this but here it is kinda a new info cuz IF someone doing this swap they already have oil pan or they make custom one.  @Dose Pipe Sutututu Yeah it is AWD RB25DET NEO Yeah as you mentioned the pick up is in a different place ...but i do not drift or track the car. It is and will be strictly street and just "casual" weekend cruiser. With that "custom" pan as shown in the video...could there be some problems?  For others. Iam sorry if that topic "looks" like i want to show/boost some YT channel or numbers. Iam quite the opposite.  I would rather drive my car thru sewers than get the attention that this car gets here. I do not have any YT channel nor IG/Twitter or TikTok. I just want some info from time to time cuz here...there is none :-)
