Ok so this is the problem.

Took off in first, snapped second and the car cut out.

Started and stalled the car for 200 metres to get it off the road. (not fun on a main road at night in the wet)

Check the engine and found the cooler pipe from the throttle body which goes to the hole under the battery had pooped off. (greddy type m intercooler)

cool so put it back on started the car and now its missing but not really stalling

it misses at idle and under load

I thought I could have fouled the plugs so I gave it I kick in the arse to clear it out

no good still missing

took off AFM while engine was running, car cuts out,

started the car with AFM off, high idle missing is a little better but still there

drive the car home, missing at all RPM barely drivable

Mods on the car thats relivant

r33 turbo

greddy intercooler

3 inch zurst

12psi

greddy profec b spec 2

fuel pressure gauge

air fuel gauge

volts gauge

Here is some extra data

1. I always get popping from the intake manifold when I cold start and backfire between gears so just im guessing the backfire could have caused back pressure and the cooler pipe to pop. This is probably a timing/tune related issue but something to add anyway.

2. the last thing i did to the car was reinstall the fuel pressure gauge sender

So what could have caused the problem?

Is the missing the result of the problem or the cause?

Ideas so far

1.plugs are still fouled (clean, test) but wouldn't have caused the pipe to pop

3.coils? Pull 1 at a time to test for change

basically my mate and i drive 35kms to work together everyday and he wroteoff his 180sx to weeks ago so we are carless unless i can find a solution

Please help

Your pipes popped off due to bad clamp or weak wrist while tightening clamp.

your car runs like crap now due to the 200m of driving worth of fuel that was dumped on the plugs with no air to mix with.

resolution.

1.) use better clamps or use wanking hand to tighten clamps properly (this hand will be stronger).

2.) buy 6 new NGK copper plugs with 0.8mm gap and put them in (wanking hand tightness not required for putting in plugs)

as for your other little problems.

you have a car with an ecu that was tuned SAFELY for 10 psi through a turbo of size X

you now have 12 psi crammed in to it through a turbo that flows 15% more at same boost levels as stock turbo.

I'm sure a remap/chip would resolve the little misfires up top etc.

speak to Toshi or CEF11E from these forums for remap options.

thanks for being so candid hahaha im still laughing.

i got a new set of NGK Coppers BCPR6ES to go in tonight (fingers crossed)

i did give it a good pumping for a couple of minutes afterwards but maybe there stuffed

at $3 a plug i dont care. hehe

as for a remap ive had a pfc and hand controller sitting in my shed for 6 months now.

im trying the get the money together for a major service, tune and to put my hks cam gears in.

im nearly there so hopefully your right.

ill test tonight a post results.

thanks guys.

plugs will fix it. reason being is that because the cooler pipe popps off no air goes to the engine and the injector is letting in heaps of fuel with fowles the plugs.

thanks guys for your input.

6 dead spark plugs later and the car is flying again. i had the some ngk plugs in it before but they were 7's. the 6's are smooth as.

very happy

yeah still need cash for PFC tune but i still made 180kw atw on the dyno so still a healthy figure.

My cars intercooler piping popped off a while back, I put it back on and things went alright. It came off again, and again.. til I bracketed the bastard from coming off anymore.

I drove the car to a crash repair shop to get some work done and when I went to drive it out, the car wouldnt start. Theres fuel going to it, but just no bang! :P

Could this be the same problem? And is it the same thing that I need to have a look at? :)

Sorry to ask in this thread but its basically the same concept.

Cheers...

If your using what we call here in the states.....WORM CLAMPS......... then you may want to run a bead around the ends of each pipe so the clamps have something to bit.

Or put 2 clamps on the pipe/coupling thats popping off

When I said bead I ment weld bead...

But worm clamps are :D

      2 more things I have to work out Easy one first...can anyone describe how to pull the fuel pump and sender from a 33? I can feel there is some sort of mount and clips but don't have a manual and don't know the trick......if not I'll spend some quality time in the boot witha lighter tomorrow. Second question is harder.  He had changed the upper plenum to a plazmaman but clearly got to a point with the vacuum hoses where he said "f**k it, I'm going inside for a beer" and never came back to that job because it was a mess. Am I right to think that I need: 1. Pre throttle (16mm nipple on inlet) to AAC's main 20mm fitting as the main pre throttle feed 2. ACC has a second 13m outlet joined to that 20mm fitting which I think is the pre throttle air supply for the cold start valve? 3. Cold start valve's outlet fitting then goes to Plenum (to bypass throttle?) There is some adapter on the back of the ACC with 2 fittings (13mm and 10mm), do I run the 10mm through a 1 way valve to the Brake Booster (4) and the 13mm back to a 13mm nipple on the Plenum as the Idle control (5)? 6. Run a 6mm vacuum line from the Turbosmart BOV to the Plenum? 7. Run a 5mm vacuum line from the Fuel Pressure Reg to the Plenum? 8. Run a 5mm vacuum line from the Turbosmart Boost controller to the Plenum? (Wastegate already has a pre turbo pressure source running to the solenoid then the wastegate on the other side of the bay)  Any help appreciated, the GTR is quite different setup and while the Stagea also has FFP it is different again. (And no Dose, I'm not pissing it all off and putting a ethrottle on it....)

      OK, onto some questions to try and speed up the process a little. Does anyone know what core this Garret is? I know it is a high flowed standard turbo but nothing else about it. Tag says OK 0169J - 446179-5032 Same question for the injectors, I don't know what they flow and ideally can work it out before it hits the dyno, they are a mustard yellow side feed

      Quick side trip into the engine externals, alternator and PS were in place including tensioned belts, but the PS was dry (my guess is he had the steering rack reco-ed). Filled it up with Transmax Z but it will need more bleeding once the engine is running no doubt. BTW I've said before, I don't know what kind of soft animals you have in the city, but out here they breed the rats tough. I bet they were disappointed when they tasted synthetic ATF.... Coilpacks are Splitfires with a factory loom in reasonable condition. I didn't pull one put I bet the spark plugs are new as its a new engine

      Onto intake pressure test. I have a Raceworks (damn brand thieves!) pressure test adapter that lets you apply pressure through a standard tyre valve and comes with a pressure gauge.....I just blocked off the other end immediately before the throttle body. Applied 30psi....and the turbo intake immediately popped off with a bang. Sorted that but it was still leaking, turns out there is a pinhole leak at the BOV adapter that I'll have to find a local place to TIG up. I'm sure it makes SFA difference with such a small leak but I want it to be right. Everything else up to the throttle body was good. Also cleaned and oiled the KNX cone filter, and this is the AFM if anyone can identify it (car runs a PowerFC)

      I'll send you a message, but until I know what is OK (and anything that isn't) its kind of hard to work out a fair price. BTW I'm just helping out here, ultimately it is Mel's call what she accepts but I know it will go sooner or later.
