Intermittent Problem With R32 Gtst

Hey all :)

I have a problem with my skyline. Only occasionally I will start it and begin to drive.. then when I'm accelerating it seems to lose power and slightly "bunny hop" the bunny hops are not aggressive. it just doesn't seem to be able to get to higher revs. It does happen when it's cold but by the time it's warmed up it still has the problem.as I said it only does it every now and again. Does anyone have any idea what could be wrong?

No mods except for a coke can in the blow off valve (bought like that) :P

Don't know the service history from previous owner. Has had a complete full service. Was happening before I recently got it serviced.. mechanic changed the fuel filter and spark plugs (thinking they were the cause) but problem still persists

It happens at any revs. It happens whenever I accelerate

Found this thread and am bumping it because I have a similar problem. I'll describe it in more detail though.

This happens occasionally, and only early in any drive if it does. Not like right out of my garage but 1 or 2 minutes in. I will probably happen at a frequency of about once every 3 times i drive the car.

Once it happens it will happen until i let it sit out of boost for a while and it will be ok. I even did 5 runs at autocross after this, problem did not crop up.

How violent it is depends on how much throttle i'm using. If I hold it down as i'm trying to accelerate and not let it if it reminds me as if someone who is just learning to driving a manual is driving the car. Off-boost it doesn't do this. It only does it at RPMs in which the turbo is building or holding pressure.

Same recommendations? I don't have another AFM to try otherwise I would but I could install my powerfc and put in a Z32 AFM.

I had an r32 gtst back in 2004 which would do that, the car would lurch back and forth violently under acceleration. Turned out to be a really dirty fuel filter, wasn't allowing sufficient fuel to the rail so the car was suffering fuel starvation. Upon reflection I'm surprised I didn't destroy the engine, must have been running ultra lean during those periods.

Did it do this all the time or only occasionally like it's doing for me?

I would think if it were a fuel filter it wouldn't just stop and be fine for hours.

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.

      ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.

      And if you have to drill the oil block, then just drill it for 1/4" and tap it BSP and get a 1/8 to 1/4 BSP bush. The Nissan sender will go straight in and the bush will suit the newly tapped hole. And it will be real strong, to boot.

      No it doesn't. It just needs an ezy-out to pull that broken bit of alloy out of the hole and presto chango - it will be back to being a 1/8" hole tapped NPT. as per @MBS206 recco. That would be for making what you had in alloy, in steel. If you wanted to do just that instead of remote mounting like @Duncan and I have been pushing. A steel fitting would be unbreakable (compared to that tragically skinny little alloy adapter). But remote mounting would almost certainly be 10x better. Small engineering shops abound all over the place. A lathe and 10 minutes of time = 2x six packs.
