OK, I've been learning all about upgrade turbos and boost controllers, but now it seems there's fuel controllers to learn about too! I've heard that ecus can provide sufficient fuelling to sort out higher boost levels, but is this truely effective, or do we need a fuel controller too? I already have an ecu chip which is supposed to fuel my old set up with boost jets running around 15psi, but I since the boost jets came off it smells like it's running too rich. Does this mean my ecu is set at one fuel level (too high). I certainly seem to be putting a lot of petrol in!!!

most of us guys have increased our boost sometime or other. My query is that if you increase the boost, you also increase the air temp. By increasing boost to say 13/14psi using stock ICs.The air temp will more than double, this is the last thing we need. would you get more performance and less detonation running the boost say at 10psi. hot air is bad. Anyone?

Hi all, I'm planning to change my gearbox and diff oil, i've done a search and found that 75/90 is needed for the box, i'm planning to use Redline MT90 but i can't find what goes in the diff, the manual says API-GL5 but i've got no idea what that is. Any help appreciated Baz

I've seen someone advertising a bead blasted plenum on the inside for 18% better air flow - has anyone ever seen this or had experience of this? Your thoughts please. Kindest Regards, Alex

im having big problems finding an air suspension set for my zx, i need it cause the roads around me are so crap, so i want to be able to just press a button and sssst up she goes, then when on motorways etc put her back on the deck again. iv seen it fitted to a few cars in banzie etc but they dont say who does it, iv tried searching with no luck, anybody out there help me? :)

I recently fitted Nismo Upeer link bushes to both front upper links on my 300. I was messing about with the tyres/wheels at the weekend and found the bushes on the inside of the drivers side link can be moved from left/right about 3 mm. Surely this cant be right...I cant feel sideways movement but i thought they would stay quite rigid during their lifetime. Anyone else noticed this. Cheers John Crisp

Hello, I was wondering whether any of you could help me with a little problem I seem to be having: I had a problem with my ZX TT stalling at low revs. I took it to the monkeys at Nissan, who after doing a Consult said they could find no problems. After a tip from this site, I suggested that it may be the TPS. They then said that it was and that they had repaired a bit of wiring. The revs weren't perfect afterwards, but it had actually stopped stalling. That was about 4 months ago and now it's started up again. These are the symptoms: - It only ever stalls when the engine is warmed up and seems to be especially affected after hard acceleration. -…

I'm getting a very low rumbling noise when i get to about 30mph,it seems like it sounds like it's coming from the front of the car low down somewhere,my initial though is wheel bearings........any ideas??? Could it be the turbos?

Hi All, My front passenger tyre has extreme wear on the inner side (i.e. bald) the rest of the tyre still looks like new. Drivers side still has plenty of tread although is slightly more worn on the inner side. I'm guessing this means it's not a tracking/alignment problem. Rears are also fine. Using Toyo proxys (about 3000 miles) and energy suspesion poly bushes in tension bars (checked and very tight). Any suggestion as to what coud cause this would be welcome. Possibly a suspension component bush somewhere?? I think the suspension's getting a bit tired, 105000 miles and still original. Thanks in advance. RobH

Hi can someone point me out the bits that need to be mirrored for installtion on a RHD cheers

Very smart red 300zx in Morrisons Car Wash Sunday morning 10:30 :hyper: Great looking motor Big alloys fist one i've seen in Jarrow, Tyne and Wear

I always used budget car wash but I want to look after my 300! Any idea what the best car wash and polishes are? I thought AutoGlym but now maybe Zymol. Zymol do a seal conditioner which I reckon could keep headlight, targa and other seals good. Anyone know what the best stuff is? :hyper:

does any one know who sells these kits for the 300 ???????????

decided to take the dash out today to try and quieten some of the rattles that nissan left me with, thought it was going too well..... everything was going fine but somewhere along the lines my indicators and full beams arent working! - the full beam flash is fine so to is the hazzard switch, a bit puzzled as to what has happened, have checked the fuses and they seem to be ok and now have run out of daylight!! anybody got any suggestions??? darren

My 300ZX is currently on my drive. I could make room for it in my garage but I'd have to throw load of stuff out and put my motorbike outside. It'd be a tight fit too. Is it worth garaging my 300? Does anyone else leave theirs outside? Does it cause any problems?

just brought a rear facing baby seat from mothercare,and doesent fit in the front or rear coz the seatbelts are not long enougth tried every which way possible ,and am gettin it in the neck from the misses.any advice or possible modifications out there to overcome this problem,if not im goin to be gutted and the zed will have to go :cry:

Has anyone got a link on how to do this modification ? I need a glowing 300zx rear panel !! :p Thanks for any help - Mike

Hi all. dont mean to be a pain or sound stupid but.... I brought a seat today to go in the Z. its a Corbeau and i got it cheap because there is no fitting kit. Does anyone know what the measurements for the seat mountings are as i am 60 miles away from the car for the next week and i want to get some mounts made up for it. any advice/info greatfully apreciated. si. :rolleyes:

How hard is it to swap froma J Spec interior to a UK spec leather interior? Now i know the seats will just bolt out, but i'm talking about the UK seat belts. I've bought a full UK interior and the belts are the only thing that i think will cause a problem. Are there mountings behind the panels for the UK belts to bolt onto ? and if not how would you go about this? Cheers

:dance: :hyper: Just finished fitting my auto box cooler - was a pain in the neck to route the pipes but found a gap - quite pleased and i only cost me £86 for the whole lot with vat, delivery and all the fittings.

hi i am sure that many of you have a variety of healight panels. are they just supposed to look good or are they supposed to have a function like allowing air through them!! I am asking because i have just bought a headlight panel and it doesnt have any "holes / vents" to let air through or am i supposed to get the holes / vents made before fitting!!!!! what have you guys done! cheers

Red z went pass me last night in Billinge, Sounded nice

anybody got the part numbers for the inlet spring /plate/o-ring handy as mine must be due to be changed and I need to get them ordered while my car is in bits

Hmm, This isnt I guess to good Had my Z bout a year now, had no probs with it what so ever, that was until recently! Anyway, about a week ago I noticed when I first started the car in the cold and went to pull off it stuttered for a second or too then was fine. I was down to service it the following week so didnt really worry about it too much. A week on, the hesitancy when pulling off seems to have gone, however it has been replaced by a new gift to me from my car, the gift of smoke and pure embarasement when flooring it. When the car is standing still, I can rev and let off the accel and no smoke at all. I can even drive it normaly and everythin…

im thinking of removing my air con, is there any problems with doing this. ie does the belt run anything else. also has anyone else done so. reasons are i have never used it, even though it is in full working condition, i prefer roof off. small power gains and more MPG. lol. also alternator bearings making noise fine when sprayed with a little WD40 for around a week. can these be replaced or is it a recon unit. let us know. cheers "T".......
