I have a 1990 non-turbo manual fairlady. When I start my car (from cold) no probs. Leaving her idling, after about 10 mins the revs and oil pressure will begin to drop. If I hit the accelerator, the revs drop down before going up. Sometimes stalls... once stalled it will not start again unless left for about 20 minutes, the starter motor just ticks over with absolutely no life :-\ Anyone know what I've broke? :D GaZ

just got all my heads back together and gave it a good whiles cranking to get the oil round the engine. When i put all the coil leads back it wont fire up:( it cranks fine, i hear the fuel pump go, it just doesnt fire at all! im not an expert on the engines ignition so its possible i may have a plug wrong somewhere, any ideas?

Just put 20GR's on the rear, it's difficult to see on the pic below, but do my handbrake shoes look low? Not sure how meaty they should be, but I reckon they are only 2mm at the mo. Also, when removing the discs, is there a way of making the ping/spring which holds the handbrake shoes in line(which was fused to the old disc) not pull though the metal that it's attached through, just for future ref. Here they are on anyway: :dance: Dance Banana Dance! :dance: Ta. Matt.

For those of you who are running 14psi or there abouts what is your TDC timing set at. Just making sure I can squeeze every little bit of power out of the old girl for the RR day at the moment mine is set at 12-13 TDC , just wondering if it would be safe to take it to 15

What oil should I use for the differential ? Just the standard stuff that I can buy at Halfords will do. Is it normal 90w gearbox oil? Thanks John

Is torqueing the wheel nuts really critical ? If so, what is the torque? Thanks John

Hi, as some of you already know I am awaiting delivery of my first Zed from Japan. I just have a question for all you 2+2 owners out there. Are the back seats really any use for a couple of passengers or am I restricted to giving lifts to people the size of Hobits! I am only 5ft9 myself so would not need the driver seat pushed too far back so should give em a bit more room in the back. Cheers, Justin.

C1397-51X90 Can anyone please tell me if this part number (for a transmission gasket) is listed as fitting a 1992 import n/a autobox sump ? (the one without a drain plug) Thanks John

I've been looking for a 300zx for a few weeks now...i've come across two non turbos, cheap..but one has a flatspot and often cuts out and the other starts fine but then "bogs down" and drops oil pressure, then cuts out if you come to a stop and is difficult to start....this is what i've been told..never seen cars yet as one is 230 miles away and the other is 300 miles away from me. Is this a common expensive problem?? Is it something sinister or just something simple? Any help/advice on what to watch out for would be much appreciated guys

Evening all, My car failed its mot today on some silly things, most of which are well in hand, The one I didnt know about was a blown headlight biulb, tried today to source some PIAAs but cant get a hold of them before the 5 day free retest envelope expires. Anyone local got a spare japspec bulb for sale or loan ?? Hugh 07812-586102

Just bought set of Lexus Sport Alloys 18". Checked PCD, checked ET but never gave inner diameter a thought. Took back wheel off Z and found that the Lex won't fit, the centre's too small. Dunno how practical or economic it would be to have rebates cut or whether it's better to resell them. Will cost me £25 to join Lexus site to advertise 'em there. :mad: :mad: Don't even really like them now I have 'em.:mad:

Dunno much about them other than they sound good and I want some :D (eventually :rolleyes: ) Would I need 300ZX specific ones, or are they all (the top Jap brands anyway) universal? And could I buy 2 x a single dump valve (eg from a single turbo car) and whack them both on, as long as they are the same? Cheers :) Pete

Frantically looking round for a cheap pair of front tyres.... Would like the same thread pattern as my Bridgstone SO2's if possible. Anybody heard of them, were quite resonably priced. Cheers, Dean.

Hi Guys, Car has just failed it's MOT on front worn tyres. :cry: Anyone know where can I get hold of two cheap 235/45/17 tyres for the front of my zed. Had Bridgestone S02's on before but would like something cheaper this time if possible as I'm selling her soon. Cheers for any help!! Dean. :)

Crazy Eddie........seen yours, got any more? Anyone else? Cheers.........anyone know how much? Better get a move on, if I want these, Z is booked in for sat 18th. I will phone SE aswell now and see how I get on.

Ok my engine is bust and i need a new one so i am still selling bit and bobs including my body to raise money. Anyway, here is my question. The engine will be coming out and an another going in so what can i do before the engine goes in to increase performance and make the engine more durable. I was thinking along the line of buying new turbos, forged pistons etc but the problem is i have only heard about these things but dont actually now anything about them or what they invlove. A list of all the things to do whlst the engine is out i will be helpful. Look forward to your replies. Rav

How many possible explanations are there for white smoking exhausts? It only seems to be a problem when the car is idling, but then again, who looks backwards when you're driving? :D On idle the fumes smell very petrol rich and I suspected that my JWT chip is overfuelling the car at idle revs. Would this explain it completely, and if so, how do I fix it? I don't want to go back to a standard spec chip, so would a boost/fuel controller sort it? Is there any way of checking that this is the cause before I spend money? Other options you might consider include.... disconnection of the AIVs from the exhaust? blown turbos (or seals)? family of native …

Yes, a sad attempt to get you all to read the post, sorry, but I do have a problem with my car's horn when it's very wet. The night before last it rained very heavily and in the morning when I started the car the horn came on with the engine, and stayed on until I switched the engine off. In the end I had to take out the fuse for the horn and so since then I've been driving without a working horn, though I suspect that it's dried out enough to work ok again now. Guessing that I'm not the only one with this symptom (it is a design error isn't it???) is there anyone out there who has fixed it? Ta very much.....

since i got the car i could hear a whirring noise in the cockpit only figured out last night its coming from a little sensor or fan behind the map lights which i figure is to do with the air cond any ideas how to quieten it 91 tt 2+2 manual

I'll convert my car and i need some help.My mechanic told me that when he put everything on the car i have to take it to an electrician to see the wirinng i don't know rewire any sensors? but he told me this would cost too much. Is this true? Anyone has a conversion manual or knows where i can get a quide?

There is a good chance that i'll buy a pair of HKS2530bb and 6 nismo 555cc injectors because my buddy is upgrading on the huge TD-06 20G. Do you know if SE can provide me a chip for this setup? His got an fcon v but i can't afford so many things at the same time

Hi I was wondering if anyone had a used instrument cluster of a TT model UK spec(180mph) that they wanted to sell Also was wondering if it will work on a us spec Z..Please let me know Thanks

Hi all, I have just had the most amazing quote from Bell Direct. I'm 27, 4 years NCB, one fault accident. My car is an import manual TT 2+2 tbar. How does £730 fully comp sound? A bit of a bargain me thinks!

Having fitted Blitz BOV's, what parts of the old recirculating valves need blanking off? Can you get away with just blanking off the hose which is easiest to get at? Anybody know the guy in Harrogate who fits chips etc. ? mike@guy2.com

When I slow down or accelerate slightly, the front of the car makes a creeking sound. I cant feel any movement just loud creeking like a door opening. Any ideas any one? Stuart
