when i took my zed to rockingham and was on the track, i noticed that the water temp was getting hot. we were doing a lot of 7000rpm in 2nd gear round the windy parts of the track. Did the car get hot just cause of high speed at low gear, and therefore not enough air to cool? i found that it cooled down if i did half a lap at ease. however, i think it got really hot (near the red) when the big ends went, but it was hard to keep an eye on the controls whilst chasing a porsche 911! i checked the water level and it hasnt lost anything and the oil level is good as well. sshould i get bonnett vents? and do they do any good? cheers steve

Is there suposed to be any movement at all in the rack cos on mine there is a tiny bit at each side and wondered if thas was ok or the rack was knackered any help apriciated

Right many of u know by now my car don't rev over 5500revs, it just stops there. 5Mins ago took the car out to just clear away cobwebs, got back, stopped on my drive and about 10 seconds later it conked out. It wont restart. I will try it later when its had time to cool down or whatever. Could this be a failed PTU? If it is could this be the cause of my troubles? Reading a TVR mag some geezer said his car wouldnt rev over 5.5K due to nackered solenoid. Im not sure exactly what the PTU does but its in the same system as the ignition? Thanks 4 any help. Rob :confused:

HI All, I must be the newest kid on the 300 block . I've been looking to buy a 300 for a while now, and as I'm not exactly over endowed with cash or the heir to a large fortune I need to keep running costs under control. Would anyone car to advise me on the auto / manual issue and the turbo / na aspect. I am not a speed freak, I just love the shape of the thing, but would not expect to be doing 160 mph anywhere, anytime, owing largely to cowardice ! Also it would be really helpfull if anyone could tell me few of the really obvious things to look out for - I'm not a complete idiot, but gurgling avi valves are news to me! Cheers, Jeff activearts Ps…

I have a uk spec car, and the headlight uses H3 bulbs. Obviously like everyone knows the lights are crap on this car. Question is can i change the standard 55w H3 bulb for a say for example 100w H3 bulb without any problems. Anyone tried this? Your thoughts would be helpful!

Ok im experiencing some strange goings at the moment with my 300zx and wonder if anyone can shed any light on it . When i accelarate hard im noticing that the engine gets to a point where its seems to be revving but the power is not there. As if the drive cuts out at a certain point. Have noticed on the boost gauge that when it gets to about 7 it fails to go any further.. Can anyone tell me if this is the first signs of turbo trouble or has the car gone into saftey boost ( i've heard it mentioned a few times on the forum but dont know what causes the car to switch to this mode ) Is there a few things that may cause this safety boost ?? Fault temp sensor etc …

My tick over runs betweem 950rpm and 1600rpm. Why is this? Ivan

I need an engine management ECU for '91 auto NA import. Anybody got one or know where I might try? Any lead helpfull, been off road for two weeks now. suffering from withdrawel symptoms. I may just have to buy another one - 300zx that is.

or is it still only meant to be tech???? (i'll just wait & see if this gets d*l*ted!! :D )

I have been told i may have central locking, but if i have it dosent work. Have you guys??????

My £20 membership is on its way to Craig before you think I'm cheeky for advertising on this bit of the forum! Anyway, nothing too exciting for sale, just a PTU for £100. Oh, and if anyone running 18's needs a part worn, I have an excellent nick Michelin Pilot Sport 275/35/18 £60. (check out Kwik-fit price of £362!) Take it easy. James.

Can anyone help please? There's a strange noise which my car makes every now and then. It seems to happen when driving not particularly fast.When the turbo gauge reaches about halfway and then goes back again the noise happens then. I've been told it's most probably the turbo wastegate and is perfectly normal. Does everyone else with a TT get this awful noise (hard to describe but sounds like a metalic squeak only a lot deeper!!) This spoils an otherwise lovely engine/exhaust sound and I'm sick of saying to any new passengers,when they say "What was that noise?" "Oh that,I'ts only the turbo wastegates,I'ts pefectly normal(I think?)" Cheers, F.T.

Damn there are a few 300zx for sale on here at the moment and this old model 300 for £2200 LOL! http://www.findit.co.uk/cars/performance/sports/444784.htm

Something funny happening today When engine cold on startup but foot on accelerator and the revs drop to nearly 0 before coming back and increasing. Nearly caused me to crash this morning on roundabout. Saw gap on roundabout. But the boot down to go. The revs dropped instead of increasing car nearly cut out , and took approx 2 secs to recover. Anyone have this problem before Cheerz Roy

It's not just us who suffer from the expanding garage bill http://www.toxiccustard.com/diary/2002/10.html#24 and also on this guy's site, some purely tasteless thunder chunder stories... http://www.toxiccustard.com/features/vomit/ Right, I'm off down the pub for the traditional Friday lunchtime - who wants a drink? Must be my round by now. I know it's Stella for andyduff, how about you craig. And what's the Pedant having?......Come on Nelson, I'll even get you a packet of low-fat crisps. :) Cheers - Gio

Ive read a few articles on here regarding the centre bearing for prop and rear gearbox mounts causing a rumbling noise. I have this problem with mine and was wondering if the centre bearing is a Nissan only part and that of the rear mount. I thought the noise was eminating from the gearbox itself, but Ive been told by loads of owners now that the 5sp manual box is pretty much bullet proof. The car is a UK 1990 model and is approaching 100,00 miles. Oil has been changed religiously every 3000 miles so no probs with engine...although it does tend to idle a bit rough sometimes. Anyone any ideas on that? Anyone any ideas on cost for the parts I need and where is bes…

Can anyone tell me where the on-line manual is?, has it been moved or has it gone?. If anyone has asked this before then oops!, just need to check something quickly... Cheers :cool:

Got a problem in that when the car is idling, and is completely stationary, i hear a gurling sound coming directly from in front of the dashboard. When you open the bonnet up, there is a round black circular cover (housing?) attached to the body of the car directly in front of say where the dashboard is. What is this cover for in the bonnet area and why is the gurgling sound coming from it. Any of you guys got any ideas as to the reason for this sound.Anyone else had this problem before. How do i solve it? Cheers lads, and hope you can help.
