Well over last few months the performance of my car has steadily deteriorated, nothing you could really point your finger at, not until last week when it turned into a full blown misfire, so I checked the coil pack connections, coil packs and spark plugs but nothing came of this, so I moved on to the injectors, removed the first plug to find it full of the green corrosion that has been mentioned in other threads regarding misfire problems, the other five plugs where as bad and also very brittle, so I am now waiting for new injector looms to arrive from the USA to see if cures the problem. Would it be of any benefit to use some sort of contact grease to stop this happening…

Right, I took this photo after doing about 50 miles in the Zed (letting it cool down first obviously). The radiator took about a pint of water, there is no obvious water leak but this is a regular occurrence. There is water in the radiator expansion bottle and the hose from radiator to said bottle is not blocked or kinked. I was thinking of putting some radflush through the system....what do you think?

My new Z has a rather strange knock coming from the engine which is fairly random. The noise has been apparent ever since the previous owner bought the car, and it hasn't got any worse probably in 8000 miles. The car went into Zedworld and Jamie listened to it and agreed it was bottom end and suggested it would only last 1000 miles but that was over 2 years ago! The knock is no worse now than it was 2 years ago and the knock goes away as soon as I start putting my foot down. The knock is more noticeable at low speed then goes away at faster speed. If the car is idling at a standstill you can bring the revs up slightly then the noise will start but then seem…

still got my wife nipping my ear to sell the recaros and put in a set of standard seats. i want to retrim the recaros in black leather with orange stitching she wants me to do that to a standard set what do you think? how much are the recaro seats actually worth?

as some of you may know im doing a complete nut and bolt restoration on my swb. im currently doing the floorpan so soonish ill be rebuilding the rear subframe. ill be going to quite an effort to make sure the subframe etc will be totally rust proofed and better finished than when it left the factory. At the moment i have the rear subframe from my swb and the one off my breaker, both are tt. ive got a hicas delete bar but im not sure if i want a n/a subframe instead. obviously i dont want to restore a tt one only to decide to go N/A. ok then guys what would you advise as far as i can see it the N/a will give me a lower gearing (better acceleration), is …

only the first time this year i took the mighty 300 to work i hate my job been doing it almost 18 years but that drive in with 300 was amazing pulling into the multi storey noise made everyone look plus i enjoy all the stuck up gits doctors and nurses looking at it and thinking whats that how on earth can he afford that plus enjoy going sideways when i finish and watching them shit them selves lol

I am going to Japfest2 and 'hopefully' entering the car into the power and style awards with a bit of luck. http://www.japfest2.co.uk/2010/01/01/bob-dixon-nissan-300zx-slicktop/ That's if I don't bin it at Silverstone that is :) If the car performs well at Silverstone (and that's a BIG if) I might be trying time attack as AME has offered to sponsor the car and since I've already done all my money I defo couldn't afford it on my own. So if I don't see you at Silverstone on the 18th June maybe will meet a few other zeds at Donny :)

walking down the seafront last night in Blackpool and heard this purring turned around and there was this gorgeous red convertible at the lights. Had almost the same numberplate "OKZ" as my car on it If someone on here well done mate top quality :flowers::flowers:

Saw something I couldn't refuse so had to buy it... a Black UK 300zx Twin Turbo! :ph34r: Its got loads of mods done already and is very tidy, so much more so that my NA. Its not all gravy though.. the engine is noisy but I have the TT lump I was going to put in the NA which will be fitted. It is seriously quick compared with my old TT and I'm well happy with it, theres a few things I will be changing wth regards to the looks but it'll soon be there. The engine has a bottom end noise that hasn't got any worse in the last 7000 miles and happens fairly randomly then goes away, but I'll be replacing it, and at the same time it'll have uprated intercoolers…

After 3 weeks of MOT work,:hammer: I finally got her back on 4 wheels.:clap: Problem now is, when I turn the ignition on, I do not get that familiar pre start fuel pump sound, the one that I believe pre pressurises the fuel line before start up.:taz: I did have the tank out as well as the rear sub frame etc. would this be normal after the fuel line being disconnected or do I have a more serious problem? I hope someone will shed some light soon, I hope to have her re tested next week. Thanks in advance, redwine300

I was bleeding the clutch from the bottom and had fulid comming out into a glass jar i was just then getting a peddal that feels like it was going well then it went a little hard then all of a sudden the peddel has gone and whats more i cant get the resisdence back and there seems to now be a noty feel to the pedal at the bottom . What have i done/ broke? :cursing:

well im in the middle of removing my AIV carbon Canister and the PVRP thingy but im stuck. when removing the passagner side AIV it say the bottom fuel vapour pipe below the boost pipes goes to the cross bar however mine does not it comes from here: and goes to here just under the TPS And the cross bar where it is meant to go goes to a solid pipe (at end of screw driver) now do i just blank off the pipe in the secound photo and leave the pipe in 3rd photo as it is if that makes sense???? thanks

As above, does anyone in the area have conzult? I could really do with checking out the car as she's got a running issue with a bit of hesitation. Beer tokens, tea and bacon sarnies waiting for anyone who can help me out. Cheers Pabs

I fitted my wheels the other day, and quickly discovered caliper clearance issues on the front :( I hastily popped to halfrauds for some 5mm spacers so I could at least get the old wheels off and new (too me) on, but even so clearance is tight ... maybe too tight ? I got a cutlery knife in order to check clearance, and a set of verniers on the knife blade tells me I have 1.5mm minimum. Am I right in thinking this is not enough ?

I got my guy to make me up some of these, it is exactly the same as I have on the rear but made for the inside of glass :cool3: Again in silver to match the car, would really really like the EL 300ZX lit up panel that goes here but practically impossible to get hold of :sad: so these will have to do I will probably lose the alarm sticker from here as this will clean up the area better :winkiss:

Ian Jr and I attacked our Zed this afternoon with water and polish (mainly Jr I have to admitt).....lol, but we think it is looking so nice again now. Enjoy the pics.

Come on how many blokes does this job take? I heard it was quite a job, but really......lol Great way to spend a Saturday afternoon at Chris's with a brew and watching while stuff was stripped from his breaker. Cheers to everyone who lent a hand, you know who you are.....lol.

out a good long drive today in the sun for a few hours but by the time i got home theres a bad tin rattle coming from a backbox, guessing the insides have collapsed. any way of fixing or is it new exhaust time?

well going to start on my feet template to mount the 99spec, was just wondering if there is any one with a proper 99spec that can get some measurements for me of where the spoiler goes on properly, dont want to end up putting it on and its not central or wonkey.

just posting what ive seen........ http://specialtyz.com/blog/?p=441

Mr Parcel man just dropped this off at my work :tt1: Well impressed, feel like fitting it tonight although need a few things done to go par and par with it ! I've got a polished plenum on my NA that i tried to fit but for some reason it just wouldn't sit flush and it caused so many leaks all round. Hopefully this one will fit better or i'm back to the drawing board. Big thanks to big_jim for giving this to me at a bargain price !

Question was, with larger turbos, will the 15psi duty rate of injectors still be allplicable. ie can you run biig turbos at 15 psi safely. or will boost need to be lowered. as turbos flow more air, and therefor 15 psi becomes lean. AMMENDED; for future referance.

Can you bleed your clutch on your own or is it to difficult?

can anyone please tell me or show me a picture of where the clutch fluid goes.:confused1:
