There a highish pitched whine coming from what sounds like the rear of the engine compartment. Appears both when parked and under load when the revs are between about 2500 and 3500 although I suppose that other engine noise could be drowning it out at higher revs. Also seems only to appear with a change of revs although agian that might be wishfull thinking I initially though it was a loose belt but I'm pretty sure there aren't any belts back there. It also sounds a bit like the screach of metal on metal but I've checked the oil level and that seems fine although I'm not overly happy with oil pressure levels at the moment. Any ideas. now off to the pub to drown …

My local scrappy made me an offer I couldn't refuse. It was a set of 17inch alloy wheels which came off a late model MR2, though I don't think they are original. They are 10 spoke with 10 small stud holes at the top of each spoke. At the rim end there are two allen key studs each side of the spoke. They look more decoritive than practical. the wheels are the normal alloy colour except the outer rim which shines like stainless steel. They are fitted with yokohama tyres which are less than a quarter worn. the tyre sizes are 135-40-17, the other two being 205-40-17, but I expect I could live with that for a while. They came with the wheel nuts, which being very slim h…

Hello everyone, just signed up, so Hello! Looking at buying a 300 cause they look just so great and have been doing my research :) so worked out, i want a series 2 or a series 3 tt, manual (v important) model (doesnt' have to be modded). Question i got is, how much am i looking at price wise? I was hoping to stay under £6000, but looking at the prices on here, is this being a bit ambituos? Other thing, i'm in london, and a lot of you guys seem to be too, so do you offer a, um, like rent a knowledge days, where you can come and check a car over for me (as obviously i know absolutely nothing about them :))? i'll pay you of course! many thanks!

Got a bad water leak which I'm trying to fix today. It appears to be a pipe from the driver's side turbo. It comes from a vertical metal pipe and bends round to underneath the plenum. I've removed all the extraneous sh1t from around it but I'm still struggling to get at the end underneath the plenum. There's still a pipe in the way stopping me getting to my pipe. It's about an inch in diameter and I'm going to have to shift it first. However, it doesn't appear to want to budge. Anyone any idea what it is, how to get it off, etc? Any help very much appreciated. Cheers Mike

I dont have standard alloy on my Z (VRLK Racing). Back tyres i have on are 265/40/17 (Back) and 235 on the Front . Will these give me a false speedo reading ?? Thanks

Yeh thanks to everyone for the HELP i've had over the past week, It like like we may of cracked my probs!!!!! I'll post my findings A.S.A.P all being well!!!!!.

I've just put my Z away in a garage for 12 months now, I need some money in my life for a change, but i'm not going to give up on the thing! It's got a (fresh) problem, that someone might be able to help me with. When I'm braking hard, the oil pressure guage drops to zero then when the car has stopped it comes back up to quarter the way along the gauge. It's always read low on the oil pressure so I replaced the sender unti...nop difference apart from now it registers this sudden drop in pressure. The car has also developed a loud lifter ticking sound coming from the rear o/s of the engine, this will go away with the appropriate oil additive, but soon comes back. …

Does anyone know if we are able to use universal O2 sensors on our motors or are they a specialist sensor?

My dad bought 3 carton boxes full of these about 2-3 years ago and i was wondering what's the code that's suitable for the Zed(NA and TT). Any help?

Does any body have these fitted , I know the discs are not up to much just wondering about the calipers themselves as I am sure i can use an alternative supplier for discs , any views would be much appreciated.

Hi everyone, I am having my Z resprayed and would like to know what else can I have done while its in the process (except for engine modifications)? also where can i buy new rubber seals around windscreen from?

Anyone know what happened to the zedparts.com site ?. They had a really good article about installing HKS Super SQL BOVS. Since I have these now I wouldn't mind having a look at it. Anyone else know of a tech site that has this info ?. If not I'll have to use the apexi guide from tt.net

its using magnets on the fuel outlet before gets into the injectors which organisers your fuel and pushes your bhp and fuel economy up. seemingly bikers have known about this a little while and are attaching the magnets onto their bikes for the gain. Peter

Guys, I am in the need for a new rad after Option took me old one off and said that one of the inlets on the rad (plastic bit that the rubber hose sits on) has broken so theres no point re-coring it. So, I went to this site and found an all ally rad: http://www.radiators.com/price.cfm?carengine=3.0L%2C+181ci%2C+V-6&transmission=Automatic&carmake=NISSAN&carmodel=300+ZX&caryear=1990&lookupid=463123 Now, it'll cost £300 including shipping, is this good or can I find one cheaper? Or do I settle for a standard one as the ally one is a waste of money? Thanks in advance for your advice!!;)

Drove to work this morning in the wet. As I was approaching the last set of lights befopre I arrived at the office, I heard a strange metallic noise. Not even sure if it was my car I continued and then heard it again as I was parking up. After letting the turbos cool a little I switched off and climbed out and the noise continued. It turned out to be my horn ! Some kind of intermittent short circuit causing it to blip and squeek. I open the bonnet to listen closer, but it stopped. I reset the alarm and it seems to be cured (?) - although I don't think the alarm circuit is linked to the horn at all. Is there a component of the horn that's liable to getting we…

Hi , Has anybody heard of a gas conversion of a Z32 tt ???? There is a gas conversion specialist just out side Swansea ,which i called into and asked. He told me it could be done at a price of £1500+ . He said he's never done a 300 B4 but done a few Supras twin T's . IS it safe ? , Does it shorten Engine life/Turbos , And most of all does it affect performance . Any Help/Advice would be great Thanks Darren
