I've just got an engine ECU chip for my TT. I've been told its a JWT chip, but it doesn't have a JWT label on it. Is it a copy ?? The chip has a tiny window in it where you can see the internals. Typed on the body of the chip it says............. Malaysia Copyright 1986 AMD It also has lots of letters and numbers that don't appear to mean anything. What do you think ??????? Should I put it in my car ?????? Thanks Andy

Just been for a test drive of a Z tt auto, the car looks the dogs, goes like stink but I had one reservation. From a standing start if I nailed it there was a knocking from the centre console, like a thudding noise. I couldn't reproduce it in higher gears but was definitely present from a start. What is this likely to be? My mate had a 2.8 capri that did exactly the same thing (I know theres no comparison!) it turned out to be the prop shaft bearing. If thats what it is how much is it likely to cost to get it sorted? Any help would be appreciated as I really liked the car in every other way Rod

Hi, Just Browsing the Mustang forum for a mate who has just bought one! I saw a post on there saying that antifreeze does not have as much thermal capacity as water and if you want your car to run cooler you are better off using the lowest ratio of antifreeze to water!! Weather permitting of course!!!! I admit to being puzzled as it usually says on the tin summer coolant and antifreeze?????????? Answers on a A4 piece of paper please!

Hello guys, Can anyone suggest something to remove very light scratches in plastic. I thought wet and dry paper and my brother has suggested toothpaste - any ideas? Cheers Vijay

Just a quick question I'm hoping someone might know the answer to.....at some point soon, I need to change my brakes discs. As far as I know, they are standard Nissan discs. Yesterday, a friend of mine took a quick look at the discs and said that I could skim the disc, rather than go to the cost of new ones, because there was still plenty on them. I just wondered if anyone has tried this, and how safe it is? I don't race the car (apart from the odd traffic lights incident!), and I don't do many miles in it. Is it a good idea to skim them or not?:confused:

hi guys,chap came and repaired the rear spoiler and he buggered the Nissan Fairlady decal.He will pay for a replacement.Any body know the part no?.

Hi Guys, I'm very much interested in purchasing the Azev LS wheels: 18x8.5" FRONTS and 18x10" REARS. They are 2-pieace split rims. My car is a 300ZX TT SWB Full Veilside C1 kit. All i would like to know is: Whether you think they would suit the ride or not? Has anybody got them on their Z as I would love to see a piccy? any help will be highly appreciated. "AMMAR"

problems ive got grey smoke when i first start up the car,lasts about 30 secs 1,smokey when i leave my car run at idles for about 15 mins puff of smoke usually last 30 secs( grey smoke,not black,blue or white) sometimes i get a puff off smoke when i put my foot down,this is not very often tho( grey smoke,not black,blue or white) 2 goosehonk and a high pitch noise from right turbo( i think its the turbo?i only hear the high pitch at 0+ boost) after doing an oil change. i noticed oil on lower oil feed pipe(gasket to right turbo)i couldnt see oil any higher. i noticed oil coming from front,area around fan belts, im guessing its the fly whee…

Cam belt was done 28 k ago. When its ticking over warm at 700rpm its as steady as a rock but I hear this faint noise at a low frequency that can only be described as like you know what. I think it is maybe a sticky patch or something on the cam belt because it is slow enough repeating to be coming from the cam belt once per revolution around the cams and crank etc. Anybody heard anything similar? I'd hate for it to be the noise before the bang bang bit when the belt breaks. And what is the easiest cover to get off to take a good look at the cam belt condition?

I have a few questions I want to ask! 1. My clutch is slipping (When I put my foot down the car just revs but doesn't go anywhere), what parts need changing? 2.Where can I find clear taillights for my Z and a center panel(the one where the 300zx writing lights up)? 3.the panel above the taillights that says (nissan twinturbo) on it is broken & needs changing! Where can I find one of them? 4.Are the standard turbos on the Z T28 's? Thank You for your help

I spotted a Z within half a mile from my house. Black Import, reg plate "J* **R". Anyone from in here? Cos

Chaps/Chapesses, As I rolled to a stop in traffic on the M20 this evening, I was rather disconcerted to find that the clutch would not disengage, causing embarassing stalling ... :eek: Upon restart, normal service was resumed and I managed to drive cautiously home. However, I thought I'd try holding the clutch in once home and all of a sudden, it's gone again!:mad: This time, it won't come back! A quick look under the hood reveals no clutch fluid in the resevoir, and a small puddle under the car ... so something am broke! Question is: From searching it would seem that the slave cylinder is a common point of failure; how do I diagnose ... I understand…

I have managed to find a very reasonably priced stage 1 turbo fitting shop for the Nissan 300ZX. I was going to have a go myself but because the price is so good, I am taking my car to them? £1475 inc fitting for Stage 1 hybrids!!!1 I think this is brilliant!!! Anyone else used them previously??:D

Hi guys i woz just wondering what should the tyre pressure be. I have split rims on and the tyres are 235/45/17 front and 255/40/17 at the rear. Any ideas. Ray

A couple weeks ago went to Jeffs,not for any work,just while there did Conzult,no probs except lazy O2 sensor,anyway,to me it sounded a tad noisy,had a small hollow knock ,but then alot of zeds do,but to me it sounded higher and in genral not that smooth,anyway couple days later started car,went for run and at low speed it was uneven,choppy,you could just feel it coming through the whole car,but at over 2000rpm all ok and still performs realy well,but,in the back of me mind i knew it was not all well,so today shot up to Jeffs,conzult,turns out that No6 piston low compression,80psi dry test+100psi wet,all other pistons reading around 145psi,the Conzult when doing the indiv…

Mine is pretty shot and causes a vibration almost identical to propshaft bearing. My question is I need to go to Cambridge this weekend (from London) and is that bush something that could cause real problems if it gets any worse--like wheel flying off or something? Not expecting anyone to say "oh yeah, that'll be fine" just a rough idea of "dodgyness of driving like it" cos I don't wanna catch the rip-off train. Thanks......

how do i find out if my z has been de-limited? its a jap spec, with km odometer and mph speedo fitted! :confused:

the window is rattling whenever it's up while driving.. okay when it's down... had anyone rectify this before... is it a easy thing to do? or shall i leave it to the mechanic..

Driving from my Hotel in Shipley to Bradford this morning I saw a great big FOR SALE sign in the front window of a nice purple car by the side of the road. Unfortunately it was a... shhhh... R33 Skyline GTR... I tried looking away, but I couldn't help myself.... I've got to go back that way this avo to head up to Newcastle.... should I stop for a look...? It's an S reg - how much is one of those roughly? (obv. no idea of mileage as but it looked in v. good condition) Help me - I love my Zed but I love Skyline's too!! Someone think of a reason why I should or shouldn't stop!!

Screw on tyre pressure monitors: http://www.ultraseal-notts.co.uk/tyre-pressure-monitor.html

are all zed spare wheels just steel space savers cos a mate of mine says that he's got an alloy one rod

Right, ive thought ive had a leak in me air system and it seems to be the gasket on the front of the intake before pressure is made. Its around part 16523-M on the below page; http://www.courtesyparts.com/z32/oe_turbo-hw.html The leak seems to come out round the top side of the gasket. I tightened up one of the bolts a bit but cant see how its physically possible by anything other than a shrew to get at the other bolt round the top of the pipe, this is trying to get at it from under the car. Is it possible that if that bolt is loose it will be causing the leak or is the gasket nackered? Is that a common problem? Pressurising the system from the MAS, air…

After checking the following http://www.twinturbo.net/ttnettech/auxfan/auxfan.html I still have my problem. The faq test the fan not coming on My auxillary fan seems to be on all the time or at least the majority of the time even after starting on a cold morning and I know for a fact its less than 219 Faranheite Anyone know why this could be???
