I have 4x 18inch x 8.5 JJ rims all I want to use. What tyre sizes would make a good looking and practical enough setup on stock suspension without needing a back brace? Was thinking 255 width all round or 245 on fronts? What about depth? Suggestions? Any help appreciated.

Guys quick question what is the best Gearbox and diff oil,and how much would i need for both,Thanks guys

Just plonked in the details of a zed I'm going to view tomorrow... WOW.... Very impressed with the quotes. Less than half what I pay for my little 1.4 fiesta run around. Anyone else find zeds remarkably cheap to insure?

On Friday 10 May I bought an autobox of a chap on eBay called Joshuajockey [60] He contacted me & said he can deliver it. He said I’ll cancel the eBay sale & pay him cash on delivery! (£250) When my mechanic came to fit it having checked it apparently it was u. s.! I’ve tried to contact him requesting a refund but as expected no response. That was last Tuesday. I don’t expect I will hear from him again!

Trying to diagnose major overfueling, just unplugged Maf and car stops, cannot remember or find anything to confirm if this is correct. ?

So I've taken the Zed of the road again because it seems the OEM exhaust has aged like milk and now it's crumbling, falling to bits when touched and pretty much leaking all over the place pre-catback. Luckily I have a Longlife exhaust firm in my town (also have Powerflow but I don't fancy having the exhaust thrown together by some ned with daddy issues) which I'm going to see about a 3" straight through system from the turbo's back but my question is about certain hoses/pipes that seem to feed into the OEM exhaust front pipes at the sides.... what are they? I've searched high and low to find out what they are to the point where Google probably thinks I have an exhaust f…

Hi all F.Y.I While I have been putting my engine back together I noticed a few bits missing, degrading on the cam back plate, so I looked on google and this kit came up on EBay. I was not sure what I would receive, it turned up this morning and to my surprise it’s excellent, I now have the missing rubber seals, can do the oil filter tree, rear cam seal and sump at some other time.

I have just looked on my usual State side suppliers and noticed both are now listing the OEM TT A/C Condensor as NLA. Sad times indeed.As the car's age, it really is surprising how many people want luxury items working again. It will be a struggle now seeing as the condenser was one of the biggest culprits for gas loss. How many more parts losses can we as owners stand as these fantastic cars grow older :thumbdown:

I have an issue whereby my Aux fan comes on as soon as the engine is warm. I have tried a new coolant temp sensor as well as a brand new coolant temp sensor connector. I have also checked my main fan and this is working fine and has only had a new clutch fan fitted a few months ago. The temp gauge on the dash is reading normal, so it is not overheating.... Just seems like the ECU thinks it is? Is there anything else I can check?

For the hardy types who still have hydraulic HICAS in their machines... Ocassionally on a run, the HICAS warning light came on and stayed on. Steering function remained normal and the fluid level was ok and on a re-start, after say five minutes, light operation returned to normal - for a while. Conzult provided no clues either. The HICAS sensor is basicaly a magnetically actuated reed switch which is located at the lower end of the tube attached to the bottom of the reservoir cap. The metallic sleeve at the centre of the float is a magnet, which if maintained above the level of the reed switch will not cause the reed contacts to close and consequently turn on the HIC…

I’m currently at Chris Karl’s place (ZSPEC) out in Ohio and these are going to be launched soon. Until recently, they’ve only sold US versions which have the key hole, these are now Euro/JDM compatible. I know Howard was after a set and AndrewG, well they’re soon to be released if anyone is interested - let me know.

My brakes squeak something rotten ! Can anyone recommend a fix ? My front calipers are off an R33 GTS so if I need new pads can anyone recommend a good set ? I am old and drive like it so no need for anything leaning toward 'track'. Thanks Mark

Came across this by pure chance, interesting what Quentin Wilson view on the future of the 300zx.

Hi guys As I am under the car doing the auto to manual conversion thought I would replace diff oil. Does any one know how much I will need and what is the correct oil ie is the Europarts one ok to use? Thanks

Hi my old front stabiliser rods had to be cut off so I ordered new ones. This should be simple, new OEM ones arrived no nuts, great look in my drawers find correct size nut only to find the thread is different. I can’t seem to find the part number or spec on what the nut should be, am I going mad or will be soon. Nissan OEM 54668-33P00 Front Stabilizer Sway Bar Endlink.

Hi all, I seem to have developed a coolant leak. Only noticed it once parked up this morning and saw steam coming from left side at the bottom of the windscreen. Only seems like a very slow leak, I can hear it dripping onto something hot, I guess onto the turbo. Car hasn't overheated or anything. I've had a good poke around and I cant really see where its coming from. From under the car I can just about see the end of a ropey and damp rubber hose on the passenger side as it goes into a hard line which looks like its part of the turbo. I cant see a thing from above. The hose is just above the passenger side turbo, almost between the turbo and the gearbox bell housin…

well car is idling like a dog could'nt find a vac leak so tool the maf of and it idles smooth at 750rpm so get the multimeter on the maf, its 0.39v on ignition and should be 0.8v if i've read that right and on idle its giving 1.28v which is well in the middle of 0.8v-1.5v so hmm any thoughts chaps ? or suggestions i've cleaned the connections theres no corrosion on any of them which i couldnt believe .... so still thinking the maf is maybe half dead :hammer:

Hi gents Does any one know what the part number is of the the little piece of plastic that sits at the ends of the central bar between the targa panels? panels Thank you in advance ?

hi guys going to be looking at changing my exhaust later this year hopefully, i've currently got a power flow system (which i'm not to pleased with the quality of it) the system i currently have on is 2.5" downpipes to replace the cats, into a 2.5" system which goes straight through to a single back box on each side with no x pipe, i have no idea if they are mufflers or resonators as the invoice just says tail pipes slash cut. anyhow i wanted something a little more subtle at the moment it's loud on idle & lower revs then is a lot quieter when i hit the 60mph range. i was after something quieter on idle with a bit more grunt higher up the rev range. any ideas what i s…

On the way home today I dropped a cylinder. Thankfully it turned out to be a loose injector connector and upon inspection the retaining clip had broken away. Is it possible to replace these connectors, are they easy to replace and where can I buy them from? Cheers, Chris.

Thinking of swapping out the plugs as I’ve no idea how old they are, but I can’t get to #2 or #3 because the previous owner fitted a Central 20 bracing strut which completely obscures them. The strut is bolted directly onto the studs on the front suspension turrets. Maybe a stupid question, but is it safe to undo the stud nuts to remove the strut with the car’s weight on its wheels? Logic says the weight of the car should hold everything where it is, but I’d like a better-informed opinion before I risk collapsing the whole front end! Thanks in advance

Afternoon, Looks like my oil leak is just rocker cover gaskets :clap: Replacing perished pipes while I'm at it - I'm looking for a couple. Can someone point me in the right direction - where's best to get them - is there anywhere in the UK? Any advice on other things while the top's off? Thanks in advance David I need (pics below)... (1) pipe from the brake servo. (2) breather pipe from the rocker cover - at the right rear of the engine
