I have a slight noise in 2nd and 4th gear. Its not major but there is a noticible difference between 2nd an 4th compares to 1st 3rd and 5th. Its difficult to describe but its not a whining or metalic sound. The car performs all right and theres no vibration.2nd and 4th sound a little louder. Any ideas....oops 90 manual TT

Hi folks Well, the restore to factory on my 1985 Z31 is going beautifully and he oil pressure gauge is registering now having removed the el cheapo after market single point thingy that could not handle gauge and idiot light, but the litres remaining is still flashing on E after a whole new sender unit was installed. Does one need to disconnect the battery for several hours to allow the computer to dump it's current info and recallibrate itself on reconnection? If not, please help with where to go next if you can. Also, the rear window defogger switch does not seem to want to work. Feels sloppy and doesnt want to engage by the feel of it.Replace? and if so…

Any ideas people??????

Help!!!! does anyone know the measurements, eg toe in, for the rear tracking mine have just been replaced ... MOT fail. Thanx Jon

Anybody got one? I'm thinking of getting one as getting worried about my security at the moment with a few problems at home shall we say... :( Where's the cheapest place to buy?

hello folks, currently using a snooper 715i detector, which has proved invaluable in both my old tvr and now the zed. Been 'thinking' about this new road angel mallarkey. read several reviews and seems very promising, anyone on here actually using of of these little gizmos, and how does it fair to the old snoopers if you upgraded vicky x x

I recently felt some shaking on my steering wheel, hence went to get the wheels balanced, got them balanced (Kwik Fit) but the problem has actually got worse, should I go somewhere else to get them balanced up, or could it be somthing else? cheerZ

I've noticed when driving over small bumps my gear stick wobbles i think more than normal. Are there any engine or gearbox mounts that may have come lose i can tighten up?????? Sorted the low idling with the grub screw,also sorted the clutch adjustment. Seems fine now.

started up my car for the first time in about a month ( havent driven cos one of the turbos has blown) and a new noise has appeared from the engine. it sounds alot like tappet noise, increases with revs, stops the minute the engine is stopped and is coming from the offside bank of cylinders. it sounds very loud though and didnt stop after idleing for bout 3 minutes. is tappet noise something that could occur due to not driving the car for a long time and will stop once the cars been driven a few times or could it be something else enyone can think of? i know a slight bit of tappet noise is common for the first few seconds after starting up the car but i didnt think …

Hello! Does anyone know of any Tracker fitters around the Midland area with good prices, or that will travel to fit it? ;) RAC Trackstar and Tracker Monitor look good options... Thanks folks :) Pete

I've put a boost leak detector on to see if I have any leaks but it doesn't pressurize at all. I'm still getting positive boost on the car but I can't really tell if I'm hitting max boost or not cos I've just had a new clutch and flywheel put in and I'm running them in. Can anyone tell me where to start looking and if anyone knows where there is a good diagram of all the pipework so I can trace them all? Thanks Vijay

Is it next to impossible to remove the turbos from under the car? I think i'm going to replace mine to see if they're the cause of my no power at high revs, but i don't want to remove the engine, it's not practical where i live. I'm going to try jacking her up tonight and checking it out but am i stupid even thinking about it?

Does anyone know where I can get my hands on a front number plate mount? I'm after the plastic kind for a UK car

Steve E I guess you posted some helpful tips on det and retard earlier, I'm the guy running 18.5psi and i would shure like not to be, so how can i stop it. when i turn the boost controller off it still boosts past 18 and the diddy dauge on the speedo dissapears to the right. I get that horrifying noise like "goosehonk" so I thought i had boost leak. how does that work, 18psi and boost leak? do you have any ideas? I only had it all fitted 2 weeks ago running fine before that, b*****x.

Hi, My recently purchased 1992 300zx was imported into the UK about 3 years ago. Is it advisable to get it undercoated, and if so, are there different types and quality of undercoating ? I imagine the underneath must be pressure washed, is the coating they put back some kind of 'elastomeric bitumen' type of coating or what ? How are zeds generally when it comes to resisting rust (I remember the 240z was a real 'rust bucket') I would have thought the zeds to be good on this matter, but there is a new post from a zed owner saying his zed is rusted beyond repair. Thanks John

Hi people, I have just had the horrible news that my beloved 300 is not going to make it through the MOT without quite a lot of work. I've basically been told that it's pretty rotten underneath and is going to need some extensive welding. I really need some advice I guess. I have spent literally thousands on this baby, but I now being advised not to have the work done. The problem I have is that the majority of the car is good. It has a new(ish) engine with 2 huge turbo technics turbo's, boost controller and turbo timer, new items such as radiator, radiator matrix, rear mich. pilot tyres (265,40,ZR17), discs all round. It also has a huge 125DB ICE syst…

does anyone know where the fuel pump voltage regulator is please??

Arse!!! Well, I think my heater matrix is dead. Water pisses all over my left foot when taking left hand corners and on hard acceleration. It pisses into the passenger side as well of course. I've searched the relevant posts but can not find a working link to the Aussy site regarding the heater matrix removal and installation. Can someone point me to another link etc to carry out the replacement with the dash-in and fiddly method??? Is it possible that the heater matrix is fine but perhaps a pipe has come loose etc because the heater still works fine other than the leaks of course??? Cheerz Van

I'm thinking about buying a standard J-spec '97 TT with 40k miles on the clock. Trouble is I've just HPI'd it and its come back as CAT C damaged. Is it worth the bother of getting it checked out or should I leave it? What do I have to check it for and where would I have it inspected? Presumably the RAC would not be the best call? The current owner genuinely seemed surprised to find out that its been written off. What should I pay for it? Thanks for your help, hoping to join the Z community...

Hi, had my aircon emptied and regassed at the weekend as it only just worked, had 45% of the amount it should have had. But, it only works slightly better. Almost as if some valve or sensor is stuck/broken/dirty. Any ideas please..

Hi All, I've just checked the resistances of the det sensor and its ECU connector. Det sensor is reading 0.533 Mega Ohms rather than 1Mega Ohm as expected - I suppose it may just be completely sh*gged but if not, will the lower resistance make it more or less sensitive to det noise? ECU resistances are OK. I'm using an AVC-R so safety boost is no longer possible but from recent posts it appears my ignition may be being retarded which is making my engine run hot due to the high AVC-R controlled boost - this is making things worse and accelerating the detting from what I can gather...surely bypassing the det sensor in my situation can't make things worse but …

MY ZED WAS RUNNING REAL ROUGH AS ON 5 OR LESS CYLINDERS SO CLEANED PTU CONNECTIONS AND EVERYTHING WAS OK FOR A COUPLE OF DAYS. I GAVE THE CAR A GOOD BLAST THIS MORNING AND IT STARTED RUNNING REAL ROUGH AGAIN. PARKED UP AT HOME LEFT IT FOR 10 MINS WENT TO START IT AGAIN AND NOW WONT EVEN START . CHECKED FOR SPARK BUT NO SPARK AT ALL. IS THIS PTU FAILURE? IS THERE ANY WAY OF TELLING FOR SURE? CHEERS ..LEE

Just had my car back after having 2 new turbo's fitted. They are the Turbo Dynamics stage 1 / 2 with 360 degree thrust bearing and staggered gap seal e.t.c. e.t.c. (MD 275 + MD 276 models) Just before they were put on I noticed on the paperwork attached, boost set at 0.5 bar. Somebody correct me here if I'm wrong as I'm a PSI man that this equates to approx 7psi. Which in my mind is safety boost territory. When I bought my Zed the turbo's were knackered so this is the first time I've had boost, but it's not amazing bearing in mind we also have apexi intake, Iridium sparkers and de-catted along with mongoose system. Boost guage reads fine although as reli…

Has anyone fitted the ecotek unit to their zed? And/or tried the de-coking foam? Have had good press.

Not that this really matters and belive me I have no desire to attempt to prove this but........ Is the top speed of a TT manual (quoted at 155 mph) electronically limited or is that the terminal velocity? Cheers. Martin.
