anyone know of any common probs to look out for?? got a mate who wants one.

Like most of us I only get the Z out during the winter months when the weather's nice and dry. In the UK that means very rarely. The last time was 2 weks ago. So yesterday the sun's out and it's dry. I head into the garage to bring the beast out, click the button on the Sigma to unlock the car. Beep and the car's open. I jump in, put the key in the ignition, turn it, all the lights come on and....... nothing. 2 or 3 seconds later and the alarm goes off. I go thru the whole process again and again and the same thing keeps happening. So I give up. This has not happened before. I'm pretty sure it's not the battery. Anyone got any idea what could be wrong????

Morning zedders, Getting desperate to get my zed back on the road now 'cos I miss driving it. Will cost me ~£500 to get my zed up to the zcentre (from Hampshire) so that it can be 'fixed' up and be driveable again. So my Q. is, is there anywhere that specialises in zeds nearer to Hants that I can take it to and know that it will get treated right?. Cheers, Tony

On the way to the POD today I was gunning it in third a couple of times and when I got to 5,000rpm it just stopped revving and slowly slowed down. I didn't do it all the time but just a couple of times. When I got there I noticed that one of the turbo pipes on the nearside turbo wasn't on very well at the front of the car. I tightened this up and it hasn't done it again since. Would such an air leak cause this problem? Ivan :confused: :confused: :confused:

Hello all What is the range of engine revs to be expected when starting the car from cold. Mine goes to about 2000 rpm when it starts which to me is far too high. It does creap back down to about 1500 rpm after maybee 30 secs but initially i think too high. Any help appreciated Cheers John Crisp

Seems like THE topic at the moment. If I go on boost at half throttle and ease off a bit the dumping from the BOV's doesnt seem to be in synch. One is slighty ahead, this causes the car to surge forward quite a bit. Ive also noticed that the noise (i presume from the turbo's (turbo) on spool up seems to be far louder. Apart from this the car runs ok and there is no sign of any tell tale smoke from the exhausts. Any ideas on the surging and if the turbos are getting noisey would this be a good time to rob a bank even though im smoke free? Oh and I get code 55 so everthing else appears to be ok?

i have just bought a soundlab amp it is 2x125WRMS or 1x250WRMS so what sub(s) will it run am i better off getting 2 subs (will it run 2) on one and which? thanks ps its not for the z its cor my corsa z is my dads

i've got an invoice for a part from holdcroft nissan but hav'nt a clue what it could be ??? n2202058s01 n/stock trignition any ideas what it is:confused: :confused:

Whilst trying to open the drivers side door ( lock a bit stiff ) I managed to bend the titanium key , luckily I also manged to remove it from the lock without snapping the bugger. I have no spares and don't want to risk snapping it at another attempt. In the long un i should fit some remote device and/or get the lock sorted. In the meantime I'll go to the local key cutter and try to get a replacement cut. I know there was some stuff about this on the forum a few weeks back but couldn't find it ( yet ) Are these keys easy enough to copy , whilst a tad skew , or should I contact Nissan , bearing in mind I can't drive the beast until a get another key. Cheers Phi…

Just checking my oil level today on may Jap NA. The dipstick seems to say ok but when i took off the oil reservoir cap - there is no oil visible. Should i be able to see oil looking down the hole like when you look down the radiator cap and see coolant?? The car is on a slight slope - but nothing big, back end of the car is at the lower end of the slope. Its a pain in the ass having your driveway on a slope :) Thanks Barry.

I notice last night that when I hit the gas, head light power drops nearly 30-40%. Battery is replaced 2 months ago. I used more amps than before. Everything was fine until last night i guess thats why i noticed it. What kind of problem might cause this?

Hello agian guys! Seems like ages since i was last on here...:eek: Hope all is well!! Guys i need help and some info on turbos, recently my engine just collapsed on me so ive decided to get it rebuilt:rolleyes: So whilst the eng's out, might as well do the usual and get me T's upgraded.....not that ive got spare cash lying around or anything:D :D Which is y i need to know which 1's are the best to get power wise etc. I need them to handle over 400bhp easy cos im also getting forged pistons, bearings, uprated gaskets etc etc.... all info much appreciated! cheers jaz

When stumbling through the mass of automotive bits and bobs that I have accumulated over the last few years I found a small K&N filter. Looks like a crankcase filter which I may have had for an old cooper s engine a few years OK. But it is new and very shiny and surely would look better under the bonnet of my Zed as opposed to the floor of my garage. Any where benefit from a nice and shiny chrome filter with an outlet of 12-15mm without stretching it, maybe 20mm with some persuading?:confused:

hi folks, no, not a speed question. Just had entire cooling system overhauled - piece of mind etc.. AND have noticed the following, which is a little worrying. before overhaul, took AGES for warm air through vents and needle to even move, let alone reach 'normal' operating temp. NOW it is a halfway (normal) with semi warm air after approx 2 miles/5mins of 'easy' driving - i.e poodling up the road with the usual plumes of condensation out of arse end. is this normal for all your zeds, or has the garage forgotton to connect anything - needle doesn't move any further and all levels havn't depleated once normal temp reached. so. is something shagged…

On the Z I'm hoping to purchase end of this month, the bloke thinks the roof is leaking but my mate who's a mechanic & did some work on it recons it's the window not seating properly 'cause of some broken plastic thing in the door which he's gonna fix. Can the leaking Targa be a big problem to sort out if it is this? Cheers.

No this is not yet another thread debating headlight mods. I simply need to know how to change the headlight bulbs? Had a look under the hood and couldn't even figure out where to start (born techy can't you tell..) Can anyone point me to step-by-step instructions, or give me a clue??? While your at it, how are the fogs changed? Cheers

Hi folks! Ok, went to have a look/test drive of a 200SX - it was sold. Cue salesman to ask "what about a 300ZX? they're a lot more fun."... One LONG test drive later (on my own :rolleyes: ) and I'm hooked! It was an Import 2 seater targa TT, red, standard - new auto box and 55k miles... Question - before I go hand over some cash, is there anything in particular to look for on these cars?... also, what about a lot of the Jap import/dealers here in the South west - any to avoid, or any to head straight to?? Help much appreciated folks...... JFF :D

Hi, I thought you may be interested in a very simple cheap upgrade! Attach Z logo in steering wheel centre. The Z badge can be purchased from the Z Centre. Pic attached. Good luck. Geoff.

Hi everyone, I was away last week - hope you're all doing great. Anyway - I've decided I'd better look into replacing rear spoiler, as oem one is starting to perish. I know about the Z centre stuff, any ideas and addresses for Essex, Herts or nearby for rear spoilers? I've also attached a pic of my 300zxtt with the '99 spec f/bumper for you to see. Enjoy :) Geoff.

HELLO ALL GOT A FLAKY REAR SPOILER SILVER PAINT ON ONE END NOT HAPPY WITH LIFE AT ALL SO I,VE GOT 2 REMOVE THE SPOILER SO IF ANY OF U LOVELY Z OWNERS CAN HELP ON REMOVAL PROCEDURE OF SPOILER I WOULD BE VERY GRATEFUL ITS A STANDARD SPOILER ON A 91 NON TURBO AUTO CHEERS CULLY Z:confused:

So - finally I'm posting so I guess I must be serious. Here's the deal: I'm nearly 24, and currently drive a saxo VTR which I've owned for over 2 years - the car handles beautifully, and has been a joy to own. However, I feel the time has come to change it for something with a little more power. I don't want to spend a fortune changing the car and can't see that there's a more value-for-money sports car than a used Z when you combine performance and good looks (other options: fiat coupe 20V turbo = not sure about looks, fiat reliability, Scooby turbo = non-coupe looks and higher price). So I'd love a zed, and I figure a 90-92 Z won't cost much more than the s…

would anyone know why ,since i have changed the oil the oil pressure gauge is not working properly?.....its not the pump....could it be somthing simple..:confused:

Current brakes are looking tired. Feels like at least one piston is sticking, pads are low and disks look worn. So I'm thinking of upgrade however on a budget. I have done a bit of a site search on Skyline front brake disk/caliper replacement which sounds tempting, but I'm not sure which ones to go with. ( If I can find any decent ones). I have heard of R32, R33 and R34 models being used. The main problem is I will be using stock wheels. If anyone has swapped these units or knows which is the best direct replacement for a UK 1991 auto I would be very grateful for any info!! Are we talking much improved braking over the old units or should we just …

Got my Z back this week after going on 5 months. It's had a full engine rebuild with Ross pistons, Nismo steel head gaskets, oversized intercoolers (thanks to TimmyTurbo), and huge ballbearing turbo's (not sure exactly what they are; universal turbos built them and they have Garret stamped on them, but no recognisable model - GT25 , GT28 etc.) Only problem I've got now is fuelling - at 1.25bar its right on the limit of what the standard injectors and fuel pump can handle, so next week its going back to the garage for an uprated fuel pump and a fuel pressure regulator to keep me going until I can afford my 750cc injectors. The end goal is to get around 500rwhp …

Anyone know if a speedo cluster from a Series II manual will work in a Series I Auto? Thanks :)
