hey guys! just got my car serviced and found an issue when driving back on the freeway, i was going around 110 km/h and all of a sudden during acceleration, the car started to lose power and saw the speedo going the opposite way, this lasted for about 2-3 secs! was wondering what this might be? Why would the engine while accelerating bog down and loose power then regain all the power at once? its idle's and runs fine normally and this is the first time its ever happend. Its a R33 gts-t.

any feedback welcomed!

happend to me just like that

did it a few times tham afm shit it self

hey mate! i couple of people have said its the air flow meter, but its been working fine before i got my car serviced. What they did stuff up was that they accidently damaged the o2 sensor on the downpipe (by leaving it on top of the turbo and it melted) and they replaced it, but maybe they did a shoddy job? does anyone know if the O2 sensor on the down pipe is connected to the AFM in anyway?

Does this happen only on high speed cruising? It could also be the fuel pressure regulator not supplying sufficient fuel to the engine when you open the throttle.

hey mate, i drove it all last night and it didnt happen again, but the car feels very different to normal, maybe its running really rich? it seems to be less responsive than it used to be and car sounds a lot more dull/quiet than what i remember it to sound on idle?

      Is it alright to top up with just another green coolant?

      thanks GTSboy. My confusion at the moment is i am trying to locate the ignition, ECU battery power and the ECU negative The closest thing i can find is the for the S15 on Page 8 of the Wiring Specialties web page https://drive.google.com/file/d/0B9F33_M_GgENQnZ6STMxVmVNd1E/view?resourcekey=0-eZ4nNRwRoqa1qvKlWWHm8A I cannot find the same diagram for the R33 RB25DET Series 2 dash plug pin out.... Do you know what the Pins? or know where i can find the same pinout diagram for the RB dash plug? Thanks for the advice on the box... i like a 6 speed so might be on the lookout or the box now.. a topic of discussion for another post...

      Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.

      Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.
