http://www.300zx.co.uk/forums/vbpicgallery.php?do=view&g=25 It's for sale, and the owner says it's a well known car in the 300zx club...? I'm only asking because I want to buy it! So any answers/recommendations are truly appreciated. Thanks. Claus

My Power Steering keeps going heavy? I have checked the fluid and its good. Any ideas why this would happen please?

I have a nice big can of silicone and gonna lube a few bits on the car. Its ok for all the bushes etc isn't it? Also gonna go round all the cockpit / roof rubbers too!

:slap: Poss gonna get shot down in flames but i am seriously considering a R33 GTR, the reason being is in my household we have got 3 cars my SWB, Smart car (everyday) and my fiancee's mx5 all with 2 seats. Whenever i want to do something i.e go to the tip e.t.c i have to borrow my mum and dads car !!!! I have always had a soft spot for the gtr and wondered if anyone has owned one before and could comment. Thanks guys:nelson:

hello mate did you still go for the EVO calipers and 350z set if so do you still have the measurement / pics of the brackets you got made up

This morning at 8 o'clock. Heading towards Earith. Zairs?

I was getting a high idle of 1500rpm here and there when the car was warm. I cleaned out the idle control valve with some carb cleaner and the idle had stopped going high but the car did stall a couple of times. Now the car has gone back to idleing high again :cry: I think the base idle is fine, when it's not high it sits at 750 rpm. Should i take the valve off and give it a really good clean? Would cleaning the intake / butterfly's help ??

My car is going in for a full respray, but the garage has suggested all new exterior trim. Does anyone know where I can get it? what the full list is? and how much it is likely to add to the total cost of the respray? eg: scuttle panel = £x.xx trim above doors = £x.xx trim below doors = £x.xx trim at the edges of the windscreen = £x.xx has anyone actually replaced it all?

I'm about to send off an intake plenum to Z1 as a swap for a chrome one. Just wondering how whats involved in changing it? What gaskets are required? Is it just a case of disconnecting all the pipes, unbolting the coilpack brackets, unbolting the bolts that hold the plenum on and removing it?

Hello all, Just recently I have noticed that my Z has got an oil leak, when I leave in the morning for work there is a small patch of oil about centre of engine. I had a look underneath the car and found that the sump has oil on it from about half way back and thus the clutch housing and g/box and d/shaft have oil down them. It appears that may be coming from up the side of the sump and running down it and therefor causing oil on everything over it. Could the sump seal be gone?? Any ideas would be most appreciated Cheers ZX_Steve PS will get piccies up as soon as I have got camera attached.

just on the train going past fareham train station and what do i see in the car park a very nice looking z plate was something like CCZ.

Having had problems with the zed blowing PTUs I've come to the conclusion that a bodged wiring loom is at fault (taped wires everywhere) and I inteded to bypass the loom between the PTU output connector and the coilpacks to avoid the 4 volt backfeed I've been getting blowing my latest PTU. After studying the wiring diagram I saw that the PTU output connector wires, according to the diagram, go straight to the coilpacks but I have found this not to be the case on my car. The output connector wires infact go back into the ECU. Does anyone on here know why they go back to the ECU? What happens to the PTU output signal inside the ECU? I've realised that it could mean that not…

ive just sorted out my boost leak as the car was only running 0.3bar the person who mhad done then rebuild before me had replaced one of the lower inlet gaskets with the wrong one so ive sorted and put it all back and now there is a miss i scaned it a l o2 sensor was reading 0.04 and the r one was reading 0.00 so not working will?can the be doing the miss

To all the others that has replaced the front bumber. Did you use the front bumber suppot bracket: http://www.conceptzperformance.com/Cart/description.php?II=2044&Car_Type=NIS300&UID=2008042412561684.49.160.241 Did you reuse this also: http://www.conceptzperformance.com/Cart/description.php?II=2044&Car_Type=NIS300&UID=2008042412561684.49.160.241 I've replaced the front fenders and a new front bumber and would just like to know if anyone else used those parts again when the front was replaced?

At which temperature does an oil flow better? There is no temperature where oil suddenly starts to flow better. A 10W/40 for example will flow between -25C and 100C or more, but there is some difference in the rate of flow! (True viscosity at -25C is about 7000 Centistoke(cSt) units, dropping to 14 at 100C. ‘Viscosity’ is really just another name for ‘rate of flow’.) The correct question is at what (sump) temperature is an oil at a viscosity that suits a modern high-RPM engine? Present day designs are happy on an oil viscosity of 10 to 15 cSt. (But many are OK on less than 10.) 30cSt is too high at high RPM. It can lead to foaming, air entrainment and cavit…

thanks for all your help

Will a uk spec 16 row oil cooler fit on a jap spec car, will the old pipes reach the new bigger cooler ,i belive these are solid metal pipes are the threads the same between uk and jap spec .Does any one know what tread size is as well thanks taff.;)

the nice chap came today from barnsley to fix my z now running at full speed no more 34 code :dance::dance::dance::dance::dance:

Couple of questions. I have a set of uk clocks but how do i put the mileage on them correct with what it actually is? Also anyone know what the 4 wires are on the clock wireing? Which is live etc.

well done whoever has done it. looks awsome an is tonnes easier to find stuff .todays posts, new posts my topics .......awsome :D

hi guys n gals got myself some 1.2 mm mig welding tips , but there outside diameter is 8mm will these fitt ok , if not were can i get some that will fitt :duffer:

Theres always been a small amount of slack in my drive train but recently it seams to make a knocking noise when coming off and on the throttle in gear. I tend to keep it locked in 2nd most of the time as i'm always driving in London at the moment and need the revs to be in the right place. Could this be damaging it? Could it be the Torque convertor as it's locked up in 2nd and 1st gear isn't it?? Gonna have a look at it this weekend.

I partly asked this in an earlier post but never really got an answer. My subframe bushes were leaking badly so as a quick fix I got a set of the locking collars from Z1 to disguise it and hopefully lock the subframe down. I'm still getting a strange side to side wriggle when powering out of long corners and can't decide if it's a subframe problem or the rear suspension that's shot. I've tried pulling on the rear wheels and their doesn't seem to be any play. The HICAS has been completely removed. Does anybody know if these locking collars will completely clamp the subframe in position even with knackered bushes? I don't know if they are just designed to …

Everytime i start to break after going a high speed, my car feels as if its going to stall, and sometimes it does!! REally starting to annoy me, so help would be appreciated! thanks :)
