gday all

well i have been noticing that some times my boost will drop about half of what it should be, showing up both on my standard and after market boost gauges.

it happened to day so i pulled over and turned the car off and started it straight back up again and it was back to normal ( full boost)

I am running standard car, Manual. You can feel the difference in power too, feels like my old r31

any ideas any one????

cheers

Mine does it too( manual series 2 ) I'd say it's just another Nissan problem disconnect the stock boost control and fit an aftermarket one and it will stop doing it

it always good to hear someone is having the same problem, then you know your not going insane :) but on the other hand not so good for the other people!!

I was thinking it was the ecu going into limp home mode or something, no warnning lights are coming up.

It has to be electrical, to turn off the car and restart in a matter of seconds and fix the problem it cant be boost leak.

cheers

mine did that to. there a quite a few things in the trouble shooting matrix that the solenoid will remain off for .

most likely is too much boost . or afm maxing out . what mods does your car have ?

no mods, but i was talking to some one today and they said airflow meter as well, i might give that a clean and see if that changes things

mine did it more when it was stock, after the exhaust and intercooler it got less frequent. i assumed that by turning the car off and back on it kind of did a check to see if there was anthing wrong then went back to normal running. the 10 minute boost mod didnt work for me so ive got a turbosmart boost t turned up to about 64 clicks. its 6 clicks short of overboost. but still does it on cold nights accasionally.

This just started happening to me, as a temporary fix would turning the boost controller down slightly help? because mine seems to boost a bit past normal say 12psi on the gauge before cutting itself back to not going past about 6, so im assuming ive got a sensor detecting too much boost and trying to cut it back but not working properly?

    • See my post here If you put the Haltech in, you won't have to worry about any of that. And, in case you're worrying about my lack of credentials in doing your exact swap, I put a Neo in an R32. There has never been a stock boost solenoid near my car and the Neo's ECU has never cared. Nor should it, because it is electronically impossible for it to care.
    • That's 100% wrong. Did you wire in the boost sensor? If you did not, then that is 101% your answer. Neo ECUs do suck a bit.
    • Hello, I'm trying to make this thread basically the thread with all the answers to common questions regarding specifically the RB20 DE NEO + T engine, that comes in the R34. Answers will and only should be provided by those who have done this conversion or actually have some relevant real life experience please. Please feel free to ask questions in the comments if you have any so other members can answer. I feel like this thread is really needed, especially with more Americans buying (unknowingly going to regret it too) rb20 neo r34s. My first question being - What do you guys use for tuning? I have purchased a haltech elite 2500 Plug and play kit for the rb25det NEO because the ecu plug is the same, but I am unsure if any of the pins would need to be repined to match. Second question that I see asked very often - After this conversion, did you install the boost solenoid/ actuator? I see many people doing a + T setup on their rb20 NEOs while running stock RB25DET NEO ECUs with no tune. I am wondering how they are going about doing that and consistently abusing the car because many of these people have had these untuned setups running for a very long time. That was my original plan, but my engine cuts out at 5 psi of boost using the stock ecu with no tune and no boost solenoid/actuator.
    • interesting. ive read and heard otherwise over the past year. ive been doing this +t conversion on a rb20 neo using all oem rb25det neo parts including the ECU, and im having engine cut out issues when I hit around 5 psi of boost. Everywhere/everyone ive asked has told me its because I never wired in a boost solenoid/actuator to the ecu, so the ecu isn't getting the right signal once it hits 5 psi of boost, causing the engine to get shut off.
