Hi Guys, sorry for the long post I need to fix the problems that i am still facing with my 1990 2seater Manual NA. 1. The clutch pedal hisses at me unless i press it about half way down. After half way it starts to engage. When i give it a lot of gas, it stops making the hissing noise.Then on the way up it clicks at me when about half way up. I feel like it is going to snap or something. What can i do to stop this and fix the problem? 2. My BRAKE light came on the other week whilst driving to work and about 5 minutes later the HICAS and LIGHTS came on aswell. I thought nothing of it as i was planning to change my front and rear brake pads. I got all the pa…

Do you guys know anything about SR-71 300zx? Is this somekind of special edition or just homemade ? I saw one here http://www.ttzd.com/tech/ecutech.html

I have a slight "grumbling">>> coming from near-side engine bay??? What could this be? I have run in hybrid turbos (4 Months old) Air con-compressor? Regards

whats the best advice for a zed in the snow, mines an auto, and ive had it 3 months and got to grips with it in the wet, but what are these beasts like in snow, or icy roads, is it best to keep it in 2nd gear, im dreading the short journey to work with 2 inches of snow.

Started to get some hesitation from about 5000rpm onwards, but only on full throttle. If you ease off the gas pedal slightly it will continue accelerating smoothly. Also seem to get fuel smell on start up coming through air vents. Coincidence ? or separate problems ? Goin' to remove centre plastic cover in the morning and check for fuel leaks. Have tightened everything else around fuel filter and although needed tightening no change. Also goin' to change spark plugs tomorrow ? Just had a thought- I am just coming to the end of a full tank of Optimax that my UK zed hasn't had before. Perhaps? Any thoughts appreciated !!!!!:confused:

Yet another problem... My clutches byting point is right the way out on the pedal (ie push the pedal in a cm or 2 and it will slip). When i floor it it starts to slip at high revs. Clutch doomed? Perhaps a simple adjustment moving the byting point further down the pedal thus less likely to slip?? :p Any thoughts much appreciated. Roboito

Finally managed to get my Z running properly... :) Unfortunately my brakes were very spongy today, only drove it about a mile and by the end i could press the pedal to the floor and the thing was hardly sloing down... What's this likely to be? I think ill try and bleed the system tomorrow but how do i go about this? What brake fluid? By the way it's all standard stuff. Thanks ROb:confused:

Hello everybody, This is my first post on this forum so please be kind (to start with at least :) ) Just wondering if any of you have personally imported a zed and how did you find the process? Anything I should be aware of and how do I know what kind of condition it will be in mechanically - will the japanese grading system be enough? Thanks in advance James

Hi all, Further to my probs with not shifting from 2nd to 3rd, I ran the diagnostic this morning and it came up as dodgy rev sensor (1st flash is longer than the other nine). It's actually the 'power' light that flshes the error code - is this normal? I've done the related votage tests, the voltage from pins 25 and 24 increase as they should with rising revs and engine speed. Is there anything else I can test? The engine 'check' light stays on until the engine is started - can't remember if this is normal (?) Any suggestions gratefully received, I really don't want to pay my local Nissan dealer to tell me they can't do anything except a gearbox rebuild…

Hi there guys, there is a Nissan 300 for sale on ebay, its not mine but someone here might want it. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=18238&item=3104930138 Happy bidding. Seem like its had some pampering in its life, samco hoses, tracker,powerflow exhaust.

guys my box is acting funny, for a while now! any1 got a UK ecu that i could test to compare? cheers jaz p.s. cant run a diag for some reason....doesnt seem to work no more?? (AT lights dont flash??)

Anyone know any good Nissan mechanics in the Liverpool area? I'm looking to have a Z inspected before parting with my cash. I checked the RAC site and they want 310 quid :eek:

How many litres of paint do spray shops normally put on when spraying the complete car? Think paint at £453 a litre might be a bit expensive!

I've got leaks in the boot and on the right side T-top. Can anyone tell me how to fix these? I tried some epoxy on the top for a crack in the rubber, but that didn't even slow it down...

Hi All, Apart from the disturbing prospect of my sick autobox I've recently noticed that the fuel pump is hissing a bit when I start to accelerate - is this normal or is it on it's way out? TIA!! RobH

I need to change a power steering hose that comes of the bottom of the pump. Now i dont think getting it of & on should be a problem, but do i need to bleed the system or anything when i get it all back together (someone said something about working the steering from lock to lock while filling the fluid up) do i need to do this? if so do i need the engine running at the same time? or is this all completely wrong. :( :(

Hi everyone...i would just like to say a quick hello..its been a couple of years since i was on this forum last..there are lots of new names and still lots of old one good to see it still as busy as ever....my last user name was jiz but it is now jiz300....anyway it is good to be back....

anyone on here got a jspec headlamp bulb for sell, not full beam, Nissan dealer here 7 day delivery:mad: :mad: any help appreciated :D

Hi All, I'm assuming my autobox is completely f*ckd (?) It still shifts nicely from 1st to 2nd but that's where it ends :-( no 3rd gear... Anybody else suffered this type of failure?? Any suggestions for a fix (for the car - not me!) Are the gears controlled by individual solenoids - hence just one dead-un or is the whole thing trashed?? The box has been a bit sticky before but was fine after a run/rest. I could really do without this at the moment GRRRRRRR!!! Any help and advice appreciated as ever... Cheers! RobH

and yes, i've searched!!! Go a small hks turbo timer fitted in z, but never used. Turned on and played around with, no matter what setting i put it on, always shuts down after 5 secs. Anyone know where i can get a manual/copy of manual from. green led display with 4 buttons, power, memory, up & down, no model number though. thanks......

Where can I find these cars for sale? I am looking to purchase one and am having trouble finding them. Anyone got a nice one for sale, dont mind mods! Please mail me with what you have on paulcoonnoruk@hotmail.com Cheers Paul

I'm looking to replace my Gearknob...and leather cover aswell.... I'm after a silver effect as i've got a silver Zed (and we all know silver Zed's look best.) Anyone know where i can get one? Dan

This might sound like a daft question but !!!! . Having not owned a Zed before and just recently purchased one i am not to aware of what should be and shouldn,t be in the engine bay at the front on either sides are HKS Super Blow Off Valves what are these and what do they do and I presume that i will have to let the insurance company know if they are a performance upgrade

some people just shouldn't be allowed to drive a Zed :eek: http://zetton.power.ne.jp/lady/photo/leopard-seat/index.html

Having recently acquired my Z and now wishing to fit an evc iv it is apparent that all is not as it seems ! There are two pipes coming out of the inside hard pipes that go around the bay and join each other at the back with a t-piece in. Anyone know what these are for and where there supposed to be connected ? I thought they where offering the wastgates the pressure the turbos are producing ! Anyone know where the original wastegates connect to and where the original solenoids are ? Is there anyone in my area who would be willing to show me their engine bay so I could suss out where all the pipes are supposed to go as I can't find anywhere on the net with pict…
