hi everyone, I only way I can describe this is when on boost at about 3000/4000 revs accelerating, there sound to be (now and agian) a rattle coming from the passenger side turbo or around there, does any one know what this could be? cheers JIM.

I've heared that on the jap-spec cars there is a warning alarm when you go over a certain speed - is this correct? Is it the same as the tone you hear when you leave the headlighs on? Reason I ask - I haven't got that on my car, but recently, especially when I rag the car a bit when it's wet, it starts to beep at me with the headlight warning tone (at between 30 and 60 mph). It's intermittent (once a week if that), and only beeps for about 10 seconds each time. Is this the speed warning tone? If so, I'll disconnect it. Any ideas guys? Also, the car's a `90 jap spec - it has a warning beep on the reverse gear too (different tone to the one outlined above) Is that stan…

Why I shouldnt rip out 25-30 kg's worth of air con while the engines out - to improve airflow to the engine and reduce weight. I mean, if it gets that hot in the summer I can just take the bloomin roof of!

Anybody done this??? Think i need to change clutch master cylinder is this a DIY job, have looked on forums but cant find much info or is it something that needs to be done by garage??? any help guides on what is involved would be really good thanks darren

Will the standard clutch hold up to about 380-400 bhp? I got manual gearbox 14.5 psi boost JWT ECU Decatted stainless straight through HKS Super Power flow induction kit Should that give me round about the 380ish mark? Will my clutch hold out?

I'm getting steam coming from the area by the brake master cylinder - does anyone know what little buggers of water pipes are in that area? And what type of job is it to get at them? I can hear the pressure escaping but its too dark yet to see whats down there as I havent got my torch! Thanks.

hi lads bought a z32 a couple of months ago (93 TT UK) and been browsing your posts for the past few weeks. (too shy to post) Ive done a searce and nobody seems to b mentioning which GRADE of oil they use or is recommended?? I bought some 5/30 Castrol Magnetic at the weekend but later on realised that on my last car had to replace the turbo due to using thinner oil. My mechanic said that the 5/30s thinner oil had washed up the deposits in the engine and this caused the turbo to be danaged (£580 full recon unit) :eek: thinking about taking it back and swapping for 10/40s magnetic plenty of time as waiting for the rest of the parts to arrive that I ordered…

The Greddy Profec B-spec II is a small and relatively inexpensive boost controller and can be bought for as little as US$300. I bought mine from Boost Solutions when they were on special for US$299. The unit is either black or blue in colour and is about 8cm wide, 8cm deep and 2cm high. This small size allows the unit to be conveniently fitted almost anywhere. On the left of the unit are two small chrome push buttons one above the other. The top button switches between two presets and by holding the button in for two seconds turns the unit off (or on). The lower button (mode) cycles through the configuration screens. In the centre is the LCD display screen and on the…

I have done a search on previous posts but did not learn much from it. Does anyone know where I can get this system I have tried ESS-Racing but he is not making them anymore(he said that he has not got time anymore). If anyone has it fitted to their car could you tell me what you think of it. Regards Mark

My Fairlady TT is running erratically .The engine nearly stalls then recovers alternately. I have just fitted a new rad ,new heater matrix and a second hand airflow sensor .The car is undrivable and i live in the outback here in Pwllheli.All the garages are stumped.Could anybody tell me what the pinouts are and their readings of the ECU.Any help would be much appreciated Ted Rogowski

hi there, i've just become the proud owner of a 94 uk zx; something I have been dreaming of for many years. In general I have been driving round with a big stupid grin on my face for about seven weeks now. In fact to only thing to wipe the smile away, is the lack of in-car heat at 5.30 in the morning; can anyone let me know if this is a common thing with the 300zx, or should I be looking to get it sorted. cheers Nigel

Right my det sensor or cable to det sensor has given up the ghost. I have done the 1Mohm trick and Im now off safety boost and boosting up to 14psi (Boost jets). These cars are bloody quick. Thing now is det sensor worry. When I replace the clutch I will have one fitted where its meant to go as its easy when gearbox is off (Ive heard) For now is it that important if car is fuelling correctly etc I know I can hole a piston etc if its detting but is there any other way of knowing without waiting for your engine to die. Car has just been checked, tuned and setup by conzult. I looked on TT website for alternative locations of DET sensor but th…

this seems to be a depressingly common occurance with us zed owners at the mo but...i had a crash on sunday. went on a grass verge smashed two concrete posts in half and demolised a road sign all with the drivers door. i ended up in a ditch on the other side of the road. was bloody lucky really as on my way into the ditch i went between 2 trees that were closer together then the car is long...so went through at exactly the right angle to miss them. also missed a second road sign by a few inches too. its amazing how un-touched most of the car is...but my door took all the impact of the posts and sign so is completely smashed. its moved in so far it kinda looks …

Can anyone tell me how you can get your rear lights blackened (smoke colour). Is it possible to be done without a sticker?

hi everyone, I know this has been done to death on here but I still carn'nt find out why? when pulling away from start my car seems to hesitate for a second then pull away, if you get the sweet spot it pull's great but if you press it to much it waits for a bit? all my conectors are clean. ive done the following. spark plugs (ngk) air filter battery fuel filter tryed moving the setting the tps replaced the pcvvs fuel cleaner cleaned throttle bodies reset ecu there no fault codes, and the car idles perfect. the only other thing I will say is the car never seems to drive the same each day, somedays its really powerfull and other days…

Hi all, does anyone know what might be wrong with the headlamp washers. The relay on the innner wing is fine, the washer motor is fine, the push switch in the car to operate the washer also seems fine. What else can i check?

Does anyone know of any really heavy duty glass polish. All my windows are slightly pitted where car was left in the rain ( not by me ). I have tried autoglym which works but it took me an hour to do a 6" square area !!!!! Think I need something stronger and an electric polisher !

How do you do an ECU test on a manual and how do you know what error code is reported. We done it on my mates Auto by moving shift and overdrive etc.

Hi - please be kind, this is my first post :-) I have Japanese import 300ZX Fairlady, 1991. I would be the first to admit I know nothing about cars, have just loved driving it for the last 6 years! I suddenly have a cutting out problem that I am having trouble getting diagnosed and wonder if any of you have heard of before? I have spent half hour or so searching here for info but not really sure what I should be looking for. Engine starts normally, then after several minutes everything cuts out dead (happens whether driving or engine is just idling) - engine stalls and all ignition lights go off. Although I can turn the ignition back on immediately, the eng…

Hello to all, I am looking for some help please guys. I smacked up my car (see thread: kerb monster) on Monday 29 December 2003. My car has been taken to a garage to be fixed, and they initially have stated they will not write off the car, as it is fixable. Today I have received a call from my insurers engineer's dept. who inform me the garage where my car has been taken is not skilled enough to fix my car. "Do I know anyone who can do this?" They are looking to offer me cash to fix the car, but I need to get the car delivered to someone with the facilities and know-how to do this. I would obviously like to do this as locally to me as possible. (Hemel Hem…

Has anyone replaced most of their vacum hoses. Does anyone have a good picture of where they all are? I know I could search about like some sort of chimp in the engine bay but having something to work with would be useful. Cheers Chris

Mines faulty :( Just got it back from Jeff @ Zedworld (Top guy) and its running in safety boost. Ext Boost gauge is reading 10-11 psi boost but this is because of boost jetting. He has toild me to replace knock sensor but fit it onto one of the 2 tall studs at back of engine as it will still pick up detonation. Has anyone else done this. The alternative is a 1MOhm resistor to fool the ECU (not a good idea coz then it wont pick up det at all), or spend £700 removing plenum, pipes etc Alos the fuel pressure switch is faulty so Im off to get on off them too. Car is stupidly fast and Ive been told it'll be even faster when knock sensor is done. Just wonderin…

been getting an intermittant high idle which goes if I stop and start the car, so I thought about checking the TPS voltage through my AVC-R. When idling properly (around 750rpm) it show .44V, checked it ealrier when it was mucking about abit and it was nearer 0.47V.\ Question, should the TPS by constant while idling, or would it fluctuate with rpm if something else is causing it? Just checking before I go scrub the connectors, as I have a feeling TPS should be constant if foot is off the Loud peddle. Cheers guys. PS full poly bush set arrived today so if anyone wants new tesion rod bushes let me know as I'll have a set spare.
