Well, I guess it's more of an "It was you" than a "Was it you", but you were behind me, then in front of me, about 4:30 this evening on the M25 ... (Am I even allowed to post a Supra spot here?) :x: Anyway, sorry it took me a while to spot you and acknowledge you, but I was deep in conversation on my mobile (hands free, of course), and it took a while to register it was you (The Plate somewhat gives it away!). Not that I would have challenged your turbo machine in my NA Z anyway!! :smw: CheerZ, JB.

Hi, my '90 jap spec, TT has has started to rev really low (when idleing) to the piont of almost and sometimes stalling. i noticed a few months ago the revs were a little low but they went up when i put the de-mister on. but its got worse and is reving and spluttering at 500 revs till it stalls. it missfires when you rev the engine once its warmed up. ive done an ECU test and it gets a code 55(no fault) when the engines not running and a code 24(throttle valve full load) when running.i would really appreciate any advice anyone could give me. cheers SI-Z

i was thinking of having an exhaust made up that comes from the turbos then out from the side of the car rather than all the way to the back. Same principal as the racing/drag car exhasut as it obviously get rid of the gases quicker. can this be done on the 300zx and is it safe to do?? any help appreciated

Right its starting to annoy me now but every since i picked the car up (92 tt cars covered 124K) its had a ver slight mis at idle. its not bad and its from both banks of the motor. The car doesnt miss at all when above 1500 - 2000 rpm but its just one of those niggly things i`d like to fix.. the engine is sweet as a nut runs perfectly pulls like a tank no smoke nothing out of the ordinary. it does this when its hot and cold.. anyone have any ideas as to what is causing this problem ????? :( :( :confused:

Has anyone got a wiring Diagram for a series 2 94 auto and manual. Would it be Emailable and if so could someone Email it to me please.

I have a problem with my steering wheel that it has not been put on properly i though i could take it off and turn and screw it back on but the holes dont line up properly i need to turn this around as it has an arrow and wording saying top(which im guessing means needs to be at top) which it isnt I undid the bolt in the middle but the blasted thing wont budge, i dont know a lot about cars but willing to learn so if you can provide any advice i would appreciate it. Cheers

Spotted you on the M42 just oputside Brum on the 21st Nov. I was gonna wave but I was in the bird's S2000 on the way to get my car from Zedworld.

Grey Z i drve by in stevenage sunday morning, i was in the pearl white one

Shes just failed! Aparentley on the bush on front top suspension arm. Garage says need to replace whole thing (front top suspension arm). Quoted about £155 for part but they say there isnt one in the uk! So any of you traders got one? car is 89 tt z32 and I need the near side one. Also failed on tyres which I half suspected. Thoughts on which ones (not too dear!) (255 40 17) Thanks!

The power light is coming on and off for few seconds every time i start the engine.Any ideas what is it? thanks

Any help would be much appreciated. Basically my car has been stored in a garage for a few months and I went to run it a little while ago and is was misfiring on one of the cylinders I checked the plugs they are ok I even swapped them round and it was still the same cylinder, I did the same for the coil packs and it still turned out to be the same cylinder ive checked the wires and they all seam to be ok. Last week I went to start the car again and as soon as I connected the positive jump lead the car started by itself with no key in the ignition! So I disconnected the leads and it continued to run. I put the key in the ignition and removed it and it still ran, so …

What can I do to pep up my higher mileage Z? These repairs can improve performance. Over the past year or so, I had been feeling that my 90TT Z Stage III had slowly been getting a little sluggish. It seemed to be running okay though, so I thought maybe it was all in my head. It was one of those things that happened so subtley and slowly that I didn't notice it. Recently I took it in for a couple of different minor problems: Dipping idle on deceleration and when in neutral at high speeds. My mechanic discovered my EGR Valve and both PCV Valves where in a state of COMPLETE failure. Additionally, many of the 10 short little rubber hoses between the intake m…

Been on the Greddy site for instructions on the ProfecB and what I can make out is that if you tee both actuator pipes together and run the tail of this to "com" on the solenoid that should be o.k. Then take a pipe from the boost side of things[ie balance bar]and run this to the control box. Now the querie,can I simply take the electrical connectors off the original solenoidsand if so do I have to remove/replace any pipes connected to them or simply plug them up? Cheers! ;)

Other half waz out in the Z 2day....and she noticed a red warning light flikering on the dash. although its not on constant. I've since looked in a uk handbook...but my z is a jap import and the warning light is not shown in the uk handbook...is there a site anywhere that shows what all the lights are 4 on a jap import dash... Oh P.s the light looks like as a image of a back box or somthing on it with squigley lines above and pos below it...hope this helps

Spotetd you parked not too far away from Southport tain station, georgeous Z with a high level spoiler and im sure i saw some 99spec lights on it. Must have been between 11 and half past. Anyone on here?

right boost jets. 1.0mm took of the 2 inner main hoses that goto the throttle body. directly below this is a small pipe theat connects to the same area as the main hose just i bit lower down where a petal pipe comes off. this hose seems to go along the side of the engine then dissapears down about half way along i guess to the turbos. cut a section of this pipe out. installed a section of blue silicone hose from smithy with boost jet in using inline connectors and some jubilee clips put all other bits together. checked using my tim guage and getting 0.7 - 0.75 bar decide to redo so this time connect a longer piece of silicone tubing straight from meta…

not really ready to start 300zx gulf war 2 BUT, running castrol 10w60 and going to switch oil at weekend for winter driving engine details : 120,000 miles on the heads, slight "squeal" from one lifter when cold, but goes after 5 minutes of warming up (fixing in spring) turbos and small engine (pistons/blcok) have about 60,000 miles on them now mainly short journeys, not really driven hard in the winter and do about 100miles a week. anyone got any suggestions? better get in quick before this thread turns to shit :D

My air con pump doesnt work - so i dont use it, as it is pointless on a targa top anyway. however this is my problem : I got in the car the other day an pulled away and water came pissing down inside the car from behined the dash on the passenger side (over the ecu area) - there was loads of it but after a while (5 secs) it stopped. I thought maybe we had heavy rain and somehow it had worked its way through a line in the bulk head, however - the next day i garaged it over night (no rain etc) and the same thing happened again when i drove out of my garage. It feels and smells just like normal water - which is why i mentioned the bit about my air con pump not work…

Going to be fitting my Apexi induction kit this weekend. Is it just a matter of removing the 2 air boxes and fitting the Apexi straight onto the AFM? I don't need to worry about any sensors of any kind do I? Cheers, David

Got a bit of an odd one, my main interior light refuses to work and (after seeing smithys blue conversion) I have realised that my control clusters either side of the steering wheel dont light up either (never have) and also the auto gear numbers which used to work.checked fuses and they are all good (clock and map lights still work and thats on the same fuse as I remember). pulled a couple of the bulbs from the cluster and they are there and intact (may have had a blue conversion done as they have funny little blue rubber covers on them?!?!?!?) Did a search and other than checking the fuse couldnt find anything that may be the cause. its a '90 tt auto, if that …
