As some of you know I've been smoking on idle, I filled up with a tank of 95ron instead of the usual optimax, strangely there is no smoke at idle now. It may be worth trying for those with smokey idles. I've got a tank of optimax in now so ill let you know how it goes. It may be a coincidence but ive been smokey for months and its within half a tank of petrol its stopped.

Hi every 1, Finally had the car up on axle stands today to find the problem what i have been having with the rear end keep kicking out, i done a seach on here and found that others have had the same problem. When up on stands i grabbed the rear wheel at 9 and 3 o'clock position and shook, there is so much play there that it seems to be deffinitely the Hicas arm end joint where it goes to the Hicas rack, also my shocks are leaking so bad that when car is pushed on boot it just keeps bouncing up and down so i take it these are shagged too. :( I have placed this pic on here to give peeps an idea what arm i'm on about, it shows the ball joint without the rubber…

I was thinking of getting a autobox cooler from Zcentre, in Luke's instructions he says it replaces the engine oil cooler, and then you use the old one for the autobox. But the n/a does not have a oil cooler does it ? If it does'nt, can you simply use his kit for the autobax ? Will the fittings & brackets he supplies enable this ? Thanks John

fitting new clutch hose today, took it off the slave cylinder no problem, but I've rounded the nut on the other end trying to get it off!!. I've soaked it with WD40 for now and I'm gonna watch the F1, so hopefully it might come off later. Any advise? Or should I just put it all back together with original hose and take it to a garage.... James

Going for a nice trip out to the lakes when a couple of bikers wanted some which i did but... Big plumes of blue smoke when accelerating hard...the only good thing is that the other biker nearly fell off his bike cos he couldnt see :confused: Pulled over had a look and nothing, no smoke on idleing. Went out again and same again the harder i accelerate the more blue smoke. It still accelerated OK but the smoke screen it leaves behind cant be good. So come on experts how much is this one gonna cost me :confused: :eek: :cry: Kirbz

under car settings should i set it to CYL 6 SPD 2 and arrow pointing up and to the right? cos when i do the rpm read 145rpm on tickover and not 850 which it does fine till i make these settings WTF put back to CYL 1 and rpm is fine surely this should read 6 CYL also kmh is wrong in speed maybee due to conversion from kmh to mph though. is there somwhere i can go to get settings and help from as i cannot read Japanese. Cheers "T"...... :confused:

Any one got pics of Z ride height with Avo lowering springs fitted. Got Blitz jobbies but they seem too high so thinking of changing them.

I hate my Zed, think i've blown the engine!!! Its knocking like hell! noise is comeing from the drivers side, but dont sound like your usual big end knock, any ideas people??:( :( :( :(

I am trying to put in a amp & all the usual ICE stuff, and am bloody close to finishing, but at the moment I am stuck on how to get the power cable direct to the battery. At the moment I have it sitting under the glove box on the passenger side from the boot (then football started) and need to get it to the battery. Can anyone help? Cheers Daz:confused: :confused: :confused:

As said above really. New to the zed's, had a couple of test drive's, loved them so i'm having one, i've got about £5k to spend. It will be an auto so are the box's prone to anything etc etc Help me as i'm not very mechanically minded.:confused: Ta very much Rich:p

does anyone know a decent technique to remove the EGR valve and plug up the holes left? i've got the replacment instructions from the twin turbos of dallas site, but i want to remove them all together while i've got the engine out getting the turbos done. i was told theres a method using a 2p coin and some JB weld but dont know what the actual method is. any ideas? thanks, Ed

just had the MOT fail 'cause there's no rear fog on the car (Jap import) even though it passed it's previous MOT! I'm gonn'a fit a rear fog light, but wondered if there is such a thing as a standard illuminated fog switch? Ideally I would like to replace the none illuminated jap switch on the consol with one that is illuminated. Does the uk car have such a thing or anybody got/made one? Cheers

whats up with the digital clock when it keeps resetting itself.

Is a turbo autobox same as n/a? I am trying to figure out if a gasket for the autobox oil pan for a 1991 turbo will fit a 1992 n/a. Also, are the import boxes different to the UK ones ? John

This seems to be a talking point at the moment, everyone seems to have there own ideas to which turbos are the best so what are?? There is a reason why i ask because i need to find out what garrett turbos are the best for the zed ie for BHP. I'm not promising anything but i might have sorted a deal out with garretts themselves to buy turbos off them cheap but i need exact model numbers etc for the zed because a a t25 or 27 comes in about 15 different models so i need more details and hopefully i can save a few people some money and of course get myself some dirty great big tubs:rofl: Kirbz

I have a 1990 non-turbo manual fairlady. When I start my car (from cold) no probs. Leaving her idling, after about 10 mins the revs and oil pressure will begin to drop. If I hit the accelerator, the revs drop down before going up. Sometimes stalls... once stalled it will not start again unless left for about 20 minutes, the starter motor just ticks over with absolutely no life :-\ Anyone know what I've broke? :D GaZ

just got all my heads back together and gave it a good whiles cranking to get the oil round the engine. When i put all the coil leads back it wont fire up:( it cranks fine, i hear the fuel pump go, it just doesnt fire at all! im not an expert on the engines ignition so its possible i may have a plug wrong somewhere, any ideas?

Just put 20GR's on the rear, it's difficult to see on the pic below, but do my handbrake shoes look low? Not sure how meaty they should be, but I reckon they are only 2mm at the mo. Also, when removing the discs, is there a way of making the ping/spring which holds the handbrake shoes in line(which was fused to the old disc) not pull though the metal that it's attached through, just for future ref. Here they are on anyway: :dance: Dance Banana Dance! :dance: Ta. Matt.

For those of you who are running 14psi or there abouts what is your TDC timing set at. Just making sure I can squeeze every little bit of power out of the old girl for the RR day at the moment mine is set at 12-13 TDC , just wondering if it would be safe to take it to 15

What oil should I use for the differential ? Just the standard stuff that I can buy at Halfords will do. Is it normal 90w gearbox oil? Thanks John

Is torqueing the wheel nuts really critical ? If so, what is the torque? Thanks John

Hi, as some of you already know I am awaiting delivery of my first Zed from Japan. I just have a question for all you 2+2 owners out there. Are the back seats really any use for a couple of passengers or am I restricted to giving lifts to people the size of Hobits! I am only 5ft9 myself so would not need the driver seat pushed too far back so should give em a bit more room in the back. Cheers, Justin.

C1397-51X90 Can anyone please tell me if this part number (for a transmission gasket) is listed as fitting a 1992 import n/a autobox sump ? (the one without a drain plug) Thanks John

I've been looking for a 300zx for a few weeks now...i've come across two non turbos, cheap..but one has a flatspot and often cuts out and the other starts fine but then "bogs down" and drops oil pressure, then cuts out if you come to a stop and is difficult to start....this is what i've been told..never seen cars yet as one is 230 miles away and the other is 300 miles away from me. Is this a common expensive problem?? Is it something sinister or just something simple? Any help/advice on what to watch out for would be much appreciated guys
