Its a 94 j spec manual and I'm getting a distinctive whirring noise in 2nd and 4th, which gets a speeds up as rpm increases but doesn't get louder. Is it r.i.p gearbox?

Hi Guys does anyone know if a TT plenum is the same as a NA? Any help appreciated Thanks. :confused:

which way up does this fit? i think it goes on with the rubber at the top to form a seal then the rubber on oil filter will seal against that if that makes sense the only thing is if you do it this way the greddy logo is upside down. has any1 got 1 of these fitted? cheers :confused: :confused:

H reg z in s ilver spotted this morning on the m56 initially, then peeled off onto to the M60, lady driver..... on the phone :slap:

I've been getting some vibration felt thru the steering wheel and pedals at about 60mph (+/- 5mph) since changing to 17" alloys(2nd hand). Took them to garage to get them balanced and they put them on the Balancing machine. The young lad reckoned that the front drivers side alloy was buckled. He did'nt look like he probbaly knew what he was doing but with the weights removed it was giving a figure of "120". after 5 mins messing around with the weights, he got the figure down to "5" and said he would let it go out like that, but I could find I get vibration. ..and sure enough..Im still getting the vibration :( Can alloys that might be bent be re…

Idle around 1000rpm, push the throttle will see revs dip down to 750rpm (doesnt do this all the time) does it sound like a boost leak? i've checked about evrything else, the ecu is controlling the idle, with the idle valve yellow connector disconnected the car will idle at 750rpm

Right then...Phase 1 Heater controls..with automatic direction control. Found the setup to be pretty efficient, and that it was pretty good at controlling which vents the heat should come out. However discovered that with the Targa roofs off its a whole different story. It insisted on blowing hot air into the footwell only when I really needed it to blow out the dash vents. So while my feet were warm, anything north of my knees was turning blue :headvswal Is there a trick to this..or can the system defaults be altered somehow...I've read about a aircon diagnostic mode..does this offer any setting controls ? :confused:

This problem has been going on for a few weeks now when I turn the ignition on I have no ignition lights on the dash ,car starts everything works .Then the battery light glow a little ,just found that the demister does not work as well ? I have checked all the fuses 10 times and today have put the the right amp fuses in .This has only happen when I put a dvd monitor in the dash is there anybody that can shed some light on this .Because this is getting on my tits in a big way :headvswal :headvswal :confused:

Hi, I'm new to this forum (and new to owning a Z - two weeks so far and I've had plenty of teething problems). I've found lots of helpful advice on here, but now things have gone pear shaped. Cruising back up the M6 (at only 85ish), a big end went. Ouch. So now it's either new shells on the crank or a recon engine. The question is - are there any recommended garages in the Warwickshire area (preferably Leamington Spa) that I can contact. There is a main dealer but there not going to be my first point of call for this. I've just spent an arm and a leg having a full service, timing belt change, new radiator hose etc. 200 miles done so far. Looks like I bought…

Whats this all about then? :- http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=10402&item=4533387051&rd=1 What is the forums general opinion on these please Does the fact that you have to carry extra water and add extra weighty components on ur Z mean its not gonna make a slight bit of difference :confused:

and if you know where they are can you circle the pipes that feed the autobox oil to and back from the radiator on an import. thanks yas

I'm thinking about uprating my suspension and I'm looking for advice on best set up for the 300ZX. I've got a late series 1996 (Import). I've recently added a new set of wheels Imiglia F20's.

Hi all, Ive been to look at a friends zed 2day, he has had the car stood for about 3-4 months because he said it wouldnt start (imob issue he thought) so i went to look cus i fit alarms and could have a look at it it's a K reg (92?) 2+2 TT it has 180km on the clock i belive I put the battery on and just though i would start it, started first time with a little lumpy idle kept the revs at about 2k for a few minutes then it idled fine so no alarm issues... i noticed, his boost gauge only had -7 0 then i think +7 or 9 i cant quite remember at idle it sat just after -7 but when reving it the gauge only moved to just under or just over 0 didnt go over…

hi,, i have auto tt, 91 this may sound silly qestion , but do you have to stop the car put in n,, to switch it to overdrive on ,,or off, or can you do it whilst driving ,, off the throttle of course,, only asking as i a manual said i had too on previous car i owned,, ps wasnt a zed, !

Have just installed the HKS ALC unit and have a prob, The car wont go into top gear and overdrive (yes the overdrive switch is on), have checked everything that i can think of, and checked over and over again the connections, but i cant see nothing wrong? Also when you come off the gas the revs drop down to tickover RPM, even doing 70MPH.? Has anyone else fitted one of these and had the same problem? :smash: HELP

has any one fitted je pistons on a rebuild before if so which way round did you have the logo facing eg facing exhaust side etc im a bit concerned now actually panicing as dont want to carry on till i know its all ok anny help appreciated

Put my powertrix upper arms on last week, and finally set them up this weekend. Initially, without them on camber was ~ -2.5° on both fronts. Played around a bit and around -1.0° seems to give the best feel, car feels much more stable in a straight line. Set the castor up to 9° aferwards, which is where I had it before. Seems OK, steering weights up nicely. Overall, seem to be able to lean on the front much harder now than before and not use the diff to steer it so much. Odd thing is that the inital over-dartiness on turn in that I'd put down to excess toe appears to have gone, but not sure yet if that's because the toe settings have been affected by adjustin…

Hi Guys I'm thinking about fitting an adjustable fuel pressure regulator. I notice that three types seem to come up when doing a search on this forum and these are: Cartech: http://www.lextreme.com/FMU.htm Nismo: http://www.courtesyparts.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=22670-RR710US&Category_Code= FSE power boost valve: http://www.fuelsystem.co.uk/pbv.htm Is the Nismo FPR rising rate like the other two? Any comments or recommendations on the above would be much appreciated. Cheers Jon
