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?

      Rusty roof repair

      By Duncan · Posted

      Shit thing to find eh? I guess the big issue is that whatever "fix" you do now, it might slow the rust down but won't fix it. I just wanted to add that in no way is fixing sheet metal in 3 dimensions the place to start with welding....that is a pro only job because its too hard to work out where things should be, let alone doing a clean enough job that it can look OK and still be strong too.  I needed to get a new rear quarter panel on the GTR and it took a pro weeks to get the old one off cleanly, new one on in the right place and looking somewhat like it should have with most of the previous connecting panels in place. Gluing a couple of bits of metal together with a welder in the garage is doable, but that is totally different to doing panel  replacement

      first time swapping rb25det into r34

      By Duncan · Posted

      This seems to be a very popular swap since all the turbo skyline prices went through the roof! I'll let someone more familiar chime in, but I understand that yes you probably want to swap the loom in to swap out the auto TCM stuff. You should not assume everything just plugs in either, you need to check at least the ECU wiring diagram for any differences at the plug at the left headlight and probably the ones near the ECU that join the dash loom too

      first time swapping rb25det into r34

      By dingleberry · Posted

      hows it fellas, my first post here which seems crazy cos half the forums i read are like the same age as me haha. to make a long story short ive got an r34 sedan (rb25de neo auto) which im swapping to a s0/s1? rb25det, r33 big box and nismo gt pro lsd. i have the motor and gearbox all bolted up outside the car, old motor and trans out. i bought the motor with stock ecu and loom, do i switch over to that? or will it be easier to get a r34 manual ecu and keep the loom if thats even possible.  also engine mounts look different, anything else thats different or incompatible? cheers, hope this all makes sense Paddy

      SAUNSW - World Time Attack Challenge - 5 & 6 September

      By Keeper · Posted

      Plan on the day will be to park trackside. Depending on space availability we will try put a small shade tent and a few of the cars on top of the hill inside turn 3, this is an easy to get to parking area with views of Turn 2, Turn 3, Turn 4 and Turn 5 and limited other pieces of the view around the track. IMPORTANT NOTE! One consideration from previous years is from memory the trackside parking sells out before the admission tickets, for that reason I encourage anyone planning on coming to buy tickets for parking now via the official website; https://www.worldtimeattack.com/ The type of parking you are looking for is 2 Day Park & View (Access Around Venue) Vehicle Pass Only Please note this does not include admission to the event itself, remember to grab that also, and kids under 12 get in for free!
