If I could tap into the Z knowledge again please. 1990 tt jdm auto, resto well underway and heading towards mot. Engine sounds well, idles nice and pulling well but I'm getting excessive white smoke or actually steam equally from both exhausts, smoke is from idle increasing with revs when cold and also warmed up, including pure water dripping out (no coolant in it no smell, nearly fit to drink) It is using quite alot of coolant so it's definitely entering the system somewhere. I know the obvious is the head gasket but my feeling is its not as no other signs at all. My thinking is that it's getting in at exhaust side, my question is can the coolant to the turbos enter th…

I would love a set of these. Seen on FB from guy in the USA. https://www.facebook.com/300YellowZX/posts/347525507378920

Seen this morning in Dundalk.

My Z is missing the moldings which fit the underside of the boot hatch and fill the gap between the body & tail lights and the hatch itself... leaving an ugly gap and somewhere for water to creep further in than it should. I am trying to determine the parts needed and am quite certain I need the ones marked green in the diagram below (although these seem to be the only parts I can find so I hope there are no differences between LWB and SWB?). However, I have no idea what the part marked purple is or if I need that too? Also if anyone has any pictures of the underside of their hatch... that would really help me visualise what I am m…

Evening legends, I know I have a wanted ad up already about this however I’m going to keep bugging everyone until someone agrees to sell me their car ? I am after a LWB, Twin Turbo, targa, Manual in red or black. Don’t mind higher miles if it’s been maintained and I’m after one that’s on the road (or at least can be done so easily) so an MOT is preferable! Import would be preferable too, gotta love the JDM! I have a healthy budget up to £15k for the right car so please let me know.

So I’m wondering if many of you guys have used after market splash guards? I’m looking for opinions on what ones are good or not so good. If you have used them for a few years are they still in good shape or rotted away? thanks for any advice

so in a moment of madness I've just ordered an oem set of intake pipes, now I currently have hard pipes on so was wondering if anything similar to the original jubilee clamps is available (and what size I need) or would I just need to buy standard clamps?

After over 30 years of use, being pushed into 1, pulled into 2, pushed and pulled 3, 4, 5 and even the R my knob has circumcised itself Now with no directions any hole is a goal!

A reminder of the 1990 superbowl advert for the 300zx This years Superbowl is on the 13th who thinks there will be a 400z advert?

My Zed passed the MOT yesterday with the following advisories 1. near side & offside rear track rod ends have slight play (I can get) 2. rear fuel pipes at rear corroded! All pipes. 3. rear power steering pipe/hose slightly corroded. All pipes Are there any diagrams or write ups of 2 & 3 that members know of? Do they have to be custom made as I doubt they are off the shelf pipes! Any help appreciated Arthur

I’m looking to lower my Z around 20-30mm and just wanted some advice if I could still run the stock shocks and drop links etc. Any pics people have of their lowered z’s with height dropped and spacer width used would be appreciated. many thanks.

Just wanted to make a post about the Ronin Import keys. Just received mine from them and the quality is exceptional. They also can decode and cut from your original key if you send them pictures and mine was cut perfectly. Saves the hassle of finding a lock cutter who can/will cut a titanium key. I also ordered their titanium bonnet props and the quality is just as good. I have attached a picture of how mine looks (with the key itself crudely scribbled out). If anyone is interested, you can get them here: https://roninimports.com/product/300zx-titanium-key-n1/

For aftermarket engine management setups which use MAP (manifold pressure) and IAT (intake air temperature) sensors then this little adaptor for a Bosch combined MAP and IAT sensor mounted to the EGR flange on the underside of the plenum could be of interest. (NB check the manufacturer's note regarding oil in the plenum). Great to see a new Z32 product innovation! https://www.polarengineering.co/product-page/nissan-z32-300zx-mounting-adapter-for-bosch-iat-map-sensor

Hi Brains trusts.. My son had some issues with the drivers side window (2+0) not going up when he bought the car. A few days later, it would go up - no problems. Now, we can't get it down. Is there a way to remove the inner door card? There appears to be a screw that is behind the window that we obviously can't get to to undo. The switch appears to work, I hear a relay clicking inside the door when the button is pressed, the passengers side works correctly. Just as a foot note, the power mirror will go up and down etc, but won't fold in - the passengers side isn't a problem. Any ideas? It may be a blown fuse, if so, which one, where? I hav…

I have taken the battery out of the Z to charge it. always had batteries where you take out plugs when charging this battery I cannot see any vents & do not want to put on charge in case it explodes any help what to do?

1996 300zx na - left side driver from US - rough idling after disconnect and reconnect of the injector connectors ( for resistance testing). Car was running smooth before and suddenly started rough idling after doing this injector connector ohm testing, it does look like all injector wiring connectors are seated properly again. does this procedure somehow reset the ecu idle setting to factory tuning ? .. i do remember i had this issue before with this car and i had a very good z mechanic at that time and he was was able to fix it quickly .. think it was the idle screw adjustment. And possibly disconnect and reconnect of the idle valve. But not entirely sure about the…

If you have a 300zx with an airbag steering wheel and change it for an aftermarket non air bag wheel then it will fail the MOT. Supra owner over here failed his MOT with after market wheel with out the airbag so be warned.

Rebuild of the 1990 TT jap auto going well, engine back in and running. Worked through all fault codes and just code 26 left, all voltage checks ok, reading +-2v as pressure changes , replaced the sensor anyway but code remains, yes I'm resetting the codes each time. I'm starting to wonder if it does relate to the boost sensor as that doesn't appear to be connected to the eccs just the gauge. Does it actually refer to the wastegate solenoid circuit? Any help/ thoughts appreciated.

In preparation for a potential purchase of a Zed, I need some wheel inspiration! I humbly request photos of your cars so I can see what wheels look like what when fitted and, if possible, please post size and offsets etc too! Its a chance to show off ? and thanks for the help!

Hi, Would be really grateful for some advice. My car leaks on both targa sides, I know this can happen, but the seals look knackered. Also they look swollen and bloated, the previous owner must have applied some black silicone stuff to seal leaks, but it looks really irregular and rough spoiling the clean lines. My plan is to get the car resprayed and replace all the seals. I would be really grateful for suggestions on where I can get the seals (targa and door) and what your thoughts are on trying to restore the targas, seals and the original paintwork.

Hi, Just wanted some advice, just bought a 300zx, I have some Nismo Rays wheels on my Z, however they are in really poor condition, I have been quoted £160/wheel to refurb, also the outer rims cannot be chrome polished and will need to be powder coated, centre caps and bolts will be extra. I just want to know what other members think, is it worth refurbishing or consider getting alternatives? If you think alternatives would be better, any suggestions?

Pretty cool watch. https://uk.motor1.com/news/561737/citizen-nissan-fairlady-z-timepieces/

This Ebay listing made me think of three iconic members. ? https://www.ebay.co.uk/itm/154802866390?hash=item240af848d6:g:JVMAAOSwTFVh0uxO

Zed back in the garage to replace all the brake lines! I have enjoyed having the manual conversion done. Makes it more of a drivers car. I was a fan of the autobox too.

Spotted a red zed with a black tailgate in Cardiff, I swear I recognised it as a members car. It was in a lock up near an Industrial park.
