Hi ALl i hope you can help. i have an R32 rb20 with just an exhaust running about 11 psi and a haltec computer (e6k). recently the car has been going all wierd on me and i cant figure out the problem..

the car will be running fine and all of a sudden loose power and sound like it was running down a cylynder or 2, and run like a heap of sh11t, then just kick back to normal and be responsive as ever????. some times it runs like this for a few seconds, other times it can last for 10 minutes. it feels like the car is running on half the amount of cylinders and it sounds like a wrx with no power at all. i got a mate to check the leads and plugs and all seem well (plug 4 looked a little richer then the rest???) i have MSD coils?

i was told that if i had problems with the coils then the problem would be constant. but it is so random. it happens any time?? if im driving the car hard, if im at idle , if its cold start or warm??? it can happen any time. and i have no clue as to why.

can anybody help : ) please : )

check you voltages for the following:

AFM

Fuel Pump

Coils

Generally this sounds like an AFM problem as it is intermitent.

But could also be fuel pump intermitently losing voltage or trying to power a high resistance as the electric motor is about to shit itself.

Coils generally would get worse as teh engine gets hotter. i.e. it would cause the problem once the engine is warmed up.

check the AFM first.

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      Also had a look at the Nissan JP website looks like the 400r has a slightly shorter ratio than than the regular V37 3.133 VS 2.937 which from a guy who has driven both 3.69 vs 4.11 ratios in the S15 is bugger all. Seems that the AUTO Z runs the same ratio as the 400R but can't find any info as to if its an open or LSD? More often than not the auto LSD is open

      R34 power steering

      By joshuaho96 · Posted

      Do not replace the power steering lines with this stuff. If it's anything like the Chase Bays stuff it will leak and be worse than stock. The reason why the reservoir is on the LH/passenger side of the car is because that's just where the reservoir was most convenient to fit. Don't overthink this stuff. The intake/cold side of the engine is pretty busy on these cars. And again, the hardpipe is designed to be a janky power steering cooler. In theory you can replace it with a real power steering cooler but that's really only for track use where boiling the fluid is a distinct possibility. Start with the low pressure lines feeding the pump from the reservoir. Make sure there isn't a bunch of junk in the reservoir filter. Be careful to not get ATF all over the engine bay. I hate dealing with ATF spills, you can clean it up and the slightest crevice will still release more oil that can still drip over time. You also want to inspect for leaks before you make a mess and can't tell what happened. Most likely you have a leak somewhere that is allowing fluid out and air in. Failing that it's allowing air in but not fluid out. Only place I can really see that happening is on the low pressure side because the pump will pull a slight vacuum to draw fluid in. Everything after the pump is high pressure or lower pressure, approaching atmospheric by the time it returns to the reservoir.

      Skid pans in/around Sydney?

      I did a skidpan night at SMSP this week, it was much cheaper than $350. But yeah, you need to slap an LSD in that thing.  I put an OS Giken in the 370Z and it's f**king MARVELOUS even compared to Nissan's viscous LSD. So you're saying it's free now that it's a housing estate? 😂

      Nah, the car seems to run exactly as it did prior, in saying this it does "seem" to be better down low, like more eager to rev, but that may be 100% placebo effect from intake noise But, I'm not worried about it at all, in the end it is a fairly low compression NA engine that has a well shrouded intake,  if it is getting hotter IAT I cannot notice anything negative performance wise from the seat of my pants thrashing it about on the street or sitting in traffic, so meh, car now now makes induction noise so I'm happy

      Do you have an IAT sensor? It's worth checking it to see. You may be suprised how little gap you actually need to flood your engine with hot air. (I tape up my airbox for a reason) :p
