ok had my stagea for around 2 months. been awesome.

had an alarm fitted a few weeks in, all good, and just enjoying the car as it is.

But in the last couple of days i've been having problems.

Firstly - driving along in a carpark slowly, braking to go over a speed hump, when to accelerate again and noticed there was nothing - then noticed steering was heavy and dash lights were on. Car turned off!

So i managed to pull it over, put it in park and start up again - fine.

Kept driving all day with no dramas.

Next day - my missus took the car, got to the end of the street, started to pull out, and again the car cut out - she managed to pull over on the wrong side of the road with the hazards on before restarting.

She thought to herself, ok - maybe just a once off, so kept driving a little more up the road - and it happened again!

Yesterday - i went out and came home numerous times with no problems whatsoever, so wtf?

Today - driving around and noticed with slight acceleration when i was going around a round-a-bout the car jolted as if i did a bunny hop in a manual. (no change of acceleration peddle). I didnt see dash lights come on - and kept driving.

I cant seem to pin it down to cold / warm / hot temps.

I had the dvd/cd off

and A/C off to try and pin it down to something like that.

We drove the car from melb - adelaide which is 800km's and had no dramas at all in the last 2 months until a couple of days ago.

I'm thinking it may be a broken wire / bad connection on the alarm/immobiliser somewhere??? and it is cutting all power to the car.

It seems to be very inconsistent, so i cant even try to locate if a certain area, my guess is the alarm???

ANY HELP????

thanks

-Matt

Has it happened at idle? If you are able to dissconnect alarm yourself, do it and start it up/ take for drive. I worked on an RB30 last week that had a similar problem for months. I didn't find the cause. All I did was make sure dist., coil, sensor wires etc. were clean and fitted tight. Last I heard it hadn't missed a beat!! Hope you work it out easlily.

There have been a few posts about this type of thing happening. For different reasons.

The day I picked up the S1 it cut out on a slow turn into a servo, going over a speed bump. She cut out, but immediately re started. It happened a couple of days later, similar circumstances. Cut out, restart immediately.

Hasent done it again for 10 months. Peculiar.

With mine I think it was old petrol and residue needed to be flushed out. Some of the Stageas sit for months in Japan before being sold.

Could be a blocked fuel filter? Probably not as that would have been changed at compliance...

If it was the imobiliser wouldn't the alarm sound? Could just be a bad connection in the circuit though, take it back to the installer and get them to check it as they should know where to look right away.

One tip though, rather than having to stop and get it into "park" to restart, try "neutral" and you should be able to keep it rolling rather than stopping which takes a lot longer and gives you more chance of being collected by some idiot not paying due attention.

I've had a similar experience with a Mazda. Same type of symptoms but was sometimes hard to start. It ended up being the alarm itself. Part of the alarm is to cut power to the crank angle sensor, this threw a code to the computer that the distributor was not working, hence the engine would shut down. I had to turn the alarm off and reconnected the wires to the crank angle sensor so it didn't go thru the alarm.

Sounds like a vacuum/afm problem like mine had. are u running a pod filter? and check ur vacuum lines to ur manifold etc. Mine had the exact same symptoms. I found myself driving along and having to slid it into nuetral mid-turn, restart it and carry on driving. embarassing.

a rolling start lights up the 4wd light on the dash... from the one time i tried ... had to stop and restart......

i guess the computer doesnt like the car to be moving and started at teh same time

First thing is to check whether the car loses all "Power" i.e. loses dash lights etc. I had this on my car twice before it stopped completely. First thing I checked was the battery. It looked clean as, but I cleaned the inside and outside of the terminals, reconnected and "hey presto" good as gold. It also reset my ECU too!

It might not be that simple in your case, but it might be worth checking.

mine did that on several occasions on a cold start...didnt actually die..but when turning the steering..the revs will fall really2 low..then back up again ..have since replaced the battery and it hasnt done that again since...then again ..i have done up my AAC and coils ..so that could have contributed to the problem.

crazy - thanks for all the replys

it did it again to me yesterday :S :)

i have got in contact with the alarm installer - he said it sounds like a sort of cut aswell - so wednesday the alarm is going to be disconnected to try and pinpoint it to that.

the car has a brand new battery in it, and the terminals all look nice and new aswell - but i will disconnect and clean all connection areas.

i'm pretty sure the car doesnt lose all power - as the first time it happened i didnt even know the car was off (coz its so quiet inside, and i think i had the radio on)

I'm not running a pod, still the stock air box. It has a new clean panel filter in there.

I will check the vacuum lines again - i did have a quick look but couldnt find anything.

if it is the immobiliser, i'm not sure if the siren would sound... it literally may not be on for that long? it is very much like it is stalling, but without the drop in rpm (ie it will stall out with acceleration sometimes)

I am pretty sure that the fuel pump would've been changed not too long ago with compliance, also the fuel in the tank isnt very old at all - a week tops of premium.

It has not stalled at idle.

I will re-check all electrical connections and connectors are all together properly.

thankyou again :no:

I just had this problem with my '01 corolla. diagnosis was a faulty distributor. i know stageas don't have them, but i'm sure whatever gives the signal to the coils (power inducer or something?) could be playing up? i'd be checking your ignition system for a fault, not the alarm.

Had exactly the problem you first described happen to me in the middle of turning at an intersection. I started it again, and away it went. I then started to notice that the radio was cutting out as I was driving, and then when I stopped it sometimes wouldnt start again.

I just pulled off the battery leads, which I had cleaned up fine, but then pulled off the plug connected to the positive terminal and it really needed a good clean. I sanded up the terminals to ensure a good connection all over, and reconnected. No probs so far, but will post again in a week or so on how it went.

I've got the same issue in my R34 GTT, i reset the ecu and disconnected the battery it worked for like 3 weeks and now is playing up again... I am taking it a autoelectrician tomorrow but he said these things are very hard to diagnose as this is the 4th time this issue has arisen and he has looked at it once already.... He did mention that maybe it was the alternator, either faulty or the alternator is putting too much power thru the car via the battery when firstly starting to accelate or slow down and hence the car for safety reasons cuts out so not to fry anything, will let u know what he says tomorrow providing i get the car back then...

again i recomend checking the airflow meter it basicly sets your air fuel mix if there is dirt in it or its poked then it will give u a crap reading and make your car idle all screwy and shut off some times. im unsure if you have checked your factory induction kit but the foam around it some times degrades and all that stuff goes into you airflow meter and sticks to the wire inside but this is only my suggestion from a mate that use to idolise his gtr b4 he got old. hope you work it out cheerz

on a side note, yesterday I mucked around and readjusted/tightened a belt (one closest to battery). started car and she just wouldnt run right, stalled at low rpm etc. with that belt just a fraction too tight the engine had issues. I know its not the same problem, but a sidenote nonetheless.

    • Getting the setup right, is likely to cost multiples of the purchase price of the vehicle.
    • So it's a ginormous undertaking that will be a massive headache but will be sorta cool if pulled off right. And also expensive. I'm sure it'll be as expensive as buying the car itself. I don't think you could just do this build without upgrading other things to take the extra power. Probably lots of custom stuff as well. All this assuming the person has mechanical knowledge. I'm stupid enough to try it but smart enough to realize there's gonna be mistakes even with an experienced mechanic. I'm a young bloke on minimum wage that gets dopamine from air being moved around and got his knowledge from a Donut video on how engines work.]   Thanks for the response though super informative!
    • Yes, it is entirely possible to twincharge a Skyline. It is not....without problems though. There was a guy did it to an SOHC RB30 (and I think maybe it became or already was a 25/30) in a VL Commode. It was a monster. The idea is that you can run both compressors at relatively low pressure ratios, yet still end up with a quite large total pressure ratio because they multiply, not add, boost levels. So, if the blower is spun to give a 1.4:1 PR (ie, it would make ~40 kPa of boost on its own) and the turbo is set up to give a 1.4:1 PR also, then you don't get 40+40 = 80 kPa of boost, you get 1.4*1.4, which is pretty close to 100 kPa of boost. It's free real estate! This only gets better as the PRs increase. If both are set up to yield about 1.7 PR, which is only about 70 kPa or 10ish psi of boost each, you actually end up with about 1.9 bar of boost! So, inevitably it was a bit of a monster. The blower is set up as the 2nd compressor, closest to the motor, because it is a positive displacement unit, so to get the benefit of putting it in series with another compressor, it has to go second. If you put it first, it has to be bigger, because it will be breathing air at atmospheric pressure. The turbo's compressor ends up needing to be a lot larger than you'd expect, and optimised to be efficient at large mass flows and low PRs. The turbo's exhaust side needs to be quite relaxed, because it's not trying to provide the power to produce all the boost, and it has to handle ALL the exhaust flow. I think you need a much bigger wastegate than you might expect. Certainly bigger than for an engine just making the same power level turbo only. The blower effectively multiplies the base engine size. So if you put a 1.7 PR blower on a 2.5L Skyline, it's like turboing a 4.2L engine. Easy to make massive power. Plus, because the engine is blown, the blower makes boost before the turbo can even think about making boost, so it's like having that 4.2L engine all the way from idle. Fattens the torque delivery up massively. But, there are downsides. The first is trying to work out how to size the turbo according to the above. The second is that you pretty much have to give up on aircon. There's not enough space to mount everything you need. You might be able to go elec power steering pump, hidden away somewhere. but it would still be a struggle to get both the AC and the blower on the same side of the engine. Then, you have to ponder whether you want to truly intercool the thing. Ideally you would put a cooler between the turbo and the blower, so as to drop the heat out of it and gain even more benefit from the blower's positive displacement nature. But that would really need to be a water to air core, because you're never going to find enough room to run 2 sets of boost pipes out to air to air cores in the front of the car. But you still need to aftercool after the blower, because both these compressors will add a lot of heat, and you wil have the same temperature (more or less) as if you produced all that boost with a single stage, and no one in their right mind would try to run a petrol engine on high boost without a cooler (unless not using petrol, which we shall ignore for the moment). I'm of the opinnion that 2x water to air cores in the bay and 2x HXs out the front is probably the only sensible way to avoid wasting a lot of room trying to fit in long runs of boost pipe. But the struggle to locate everything in the limited space available would still be a pretty bad optimisation problem. If it was an OEM, they'd throw 20 engineers at it for a year and let them test out 30 ideas before deciding on the best layout. And they'd have the freedom to develop bespoke castings and the like, for manifolds, housings, connecting pipes to/from compressors and cores. A single person in a garage can either have one shot at it and live with the result, or spend 5 years trying to get it right.
    • Good to know, thank you!
    • It's a place for non car talk. There's whoretown which is general shit talking. But also other threads coving all sorts of stuff(a lot still semi car related)
