One of my last jobs to get the most out of the engine is to sort the O2 sensors out. The ones on my UK TT Manual are shagged. Ive got a donor fully working pair, i have the correct 3/8" offset snapon O2 socket, various bars and whatever. Took the zed out and really warmed up the tubs, to assist removal. Starting on the passenger side as it looks most awkward,, made as much space, remove battery and loom aside How the hell do you get to them?????? Anyone who has changed them on a TT, got any suggestions of how you did it, If JeffTT sees this, how do you do them????????? "Toit like a toiger" Stu

Is any one bringing a cable and software to the meet and we can all check our cars??? I have the cable and laptop which i will bring, but no software yet. Just a thought! Daz.

Will this kit plug and play in place of a series 1 ptu Thanks

Hi I've read a few posts on here that say putting on aftermarket steering wheels can effect the HICAS. The answer seems to be to fit the proper Boss. Can someone clarify the situation and explain why it causes the HICAS to play up. Cheers Ric

the few problems i have on the car could be pointing to the maf. am i correct poor fuel consumption- less than 20mpg driving very stedy i would expect nearer 30! slightly lumpy idle strong smell of fuel when accelerating hard/ going up hill. i would have thought that the lambda sensors would have corrected any fueling issues though below 3k am i right? any way to test easily

I have took a tackle to updating my rides section... But does the description thingy support HTML?

Has anyone got a quick way turning a jpg to a avatar suitable for the forum. Think it has to be 100x100

Hi mate. do you still have that picture lurking around with the 99spec bumper on the zed?

Sorry for the delay in updating you what's going on guys. Basically i've moved house rather suddenly, i popped a picture up recently of the new garage, it's brilliant. 35 foot long, double garage and lighting/heating. Makes life easier, i've got more done this last week than i have in 3 months of working at my parents house in the odd hour when i pop round :nana2: So where to start, so i've stripped down and cleaned all the metal particles from the block, torqued up the crank, pistons and conrods. The windage tray is all beaten to shape and lock tighted on. I've now fitted and torqued down the sump in place. Timing the cam was the hardest part, I us…

This might sound like a silly question, but if you found drops of oil in the catch pan you put under the car, is there anyway of telling / testing whether it´s engine oil or gearbox oil before getting under the car and investigating the source ? Cheers Maz

Ok I've searched the threads and have found a few different opinions but has anyone got the definitive answer on this. I have a set of clocks that read up to 180 and it is listed in MPH only (no KMH readings at all) They seem to be reading in KMH ie. when doing 70 MPH they read 112 on the clocks. I think I need a converter. Is this correct? if so where is the best place to get one and how are they fitted. Cheers

The boot release aint working properly. To get it to open you have to keep the lever pulled up while at the same time lifting the boot lid (easy if you have a passenger or 12 foot arms) I'm thinking it's either the catch or the struts. Anyone had a similar problem

anyone know where to get 99 spec front indicators from. think ive seen them at the z centre but are there alternatives ie smoked etc

Any one thinking of strenthaning, there 300 a 2.1mtr concreat lintal fits in :smash:nicely

My Speedo is displaying MPH but seems to be reading KMH. Could this be down to some sort of sender relay The fuel cap is not opening from the lever......Now sorted And the boot release is working but the lever has to be held up at the same time as lifting the boot And lastly I need the following repaired. Anyone know if it's much of a job. And the cigarette lighter is not working (Bummer for the sat nav) Scratch that one now fixed Cheers

hi can anyone tell me if my 300zx would have a diagnostics plug on it somewhere??....it is a 1995 twin turbo manual series 2

Visited the weigh station today, (yes i was bored) Lets see who can guess the correct weight of my zed?????? I was pretty impressed with the weight seeing as its a 2+2......

I am having trouble getting the CAS in the right place. When I took out the cas, the little location stub which is uses to make sure the CAS is in the correct position has snapped off. Its not the cog shape on the cam which has snaped just the little locating stub. This has made getting the CAS position very hard to get right. Are there any tips on how to get it in the correct location. I tried putting the engine in top dead centre and then turning the cas until cylinder 1 fires the engine has a strange firing order when starting up so is very hard to do. Any one got suggestions on how I could get this right? Stuart

Told myself I was gonna fix this over 5 1/2 years ago but never got round to it and .......... still not done it. :wack: saw on another thread recently that the fault is most probally the white timer unit that is on the same bracket as the fuel pump relay near the fast pedal, I replaced this last night and still the same, stops in middle of screen in random places, anyone any idea's :D

could anyone please tell me where i can get hold of an upper plenum gasket i think the part number is 14035m or does anyone have one they dont need. i would be very greatful to anyone how can help. thanks guys. P.S if anyone is intrested i have 2 standard turbos for sale they might need reconed.

I have sourced one of these on the internet suitable for a 300ZX. How exactly does it work? What advantages does it have? And also is it likely to damage anything? Thanks, Dan

Some flash bloke,looks slightly bald, in a dirty car! going round round about wheel spinning :rofl::rofl:

Hi all If you get a honking sound does that mean the recirc valves are on the way out? if they are worn could this effect the idle or create a misfire? would these be picked up on a boost test? how easy or these to replace and where are they located? wheres the best place to buy these from?

Have an annoying rattle that sounds like it is coming from the rear diff area. Happens below 2000RPM (usually in 2nd or 3rd when the engine is working hard) and sounds like the exhaust is hitting a heat shield and then fades away as I accelerate. I have new oil in both G-boxes, new Nismo G-Box mount, single piece drive shaft. Noise was there before I made these changes as well. Tonight I have removed the centre heat shield and starter heat shield to eliminate those and the rattle is the same. Noticed that the drive shaft can rotate about 10-15 degrees without the wheels moving. Is this movement normal? Help greatly appreciated!:D

Sloppy and imprecise steering is just horrible, there are many factors that need to be looked if your zeds not going well in the pointing department, tyres , tyre pressures, tension road bushes, steering arms, steering knuckles, etc. etc. But oddly one area that often gets overlooked is the steering rack bushes, these two rather large rubber sleeves keep the steering rack in position laterally. Check out the photo's below see the state of the two bushes in particular the right hand one which was completely useless, in the next photo you can see the amount of insecure movement of the rack due to the worn bush, basically when turning at a junction the rack was…
