I'm gonna rip out the tossy standard speakers and fit some nice Pioneers. Me question is the speaker that I want comes in both 16cm and 17cm size. I know the fronts are 6.5" but 16cm and 17cm are both almost 6.5" and I was wondering if it'd be better to have slighty bigger or slightly smaller than 6.5"??? Any advice appreciated, cos I don't want to remove the door interiors more than once!!

searched and no one has asked, so here goes. Would it be at all feasible to have the t-bar on our zeds some way 'cut out' and then have a fabricated locking mechanism placed on the end of the t-bar, therefore locking it into place when required. After cleaning the beast yesterday, this occured to me whilst cleaning out the drain channells in the top. Obviously this would severly weaken the structure of the car on an impact with the lid off, but surely with the lids on, more or less the same as before, but with the added bonus of having a completely removable roof in the summer. So whatta y'all think, talking *****x or viable????? vicky x x

Hi all, Been having some problems with the A/C. Apparently compressor is OK, pressure of gas is fine, fuses OK, but no cold air. At the weekend found the connector on the receiver (behind the front bumper) loose. Cleaned and refitted and now the A/C seems to be making a noise where it wasn't before. Sounds like a cross between fan noise and the noise a fridge makes?!! It seems to be coming from behind the glovebox. Would the poor receiver connection have stopped the system working before? With it not flowing gas, would the pressures have been measured wrong? Any ideas? expansion valve or something? Is the A/C supposed to sound like a fridg…

Hi, Can anyone help with with these? I'm looking to buy one of each and just wanted to know if I need anything special? I'm looking at the Gunson stuff: http://www.gunson.co.uk/acatalog/Gunson_Catalogue_Timing_Lights_4.html http://www.gunson.co.uk/acatalog/Gunson_Catalogue_General_Test___Tune_Equipment_8.html I also see that they sell a "remote start/crank" switch, how would these connect up o a 300? Cheers Vijay

Hi all, Bit of advice required......................Only had my Z for a few months but circumstances dictate that she has to go. Not sure what she's worth to be honest so hopefully you lot can give me some ball park figures. Right, the spec.

Firstly when someone said it's a little tricky to change the two bushes situated underneath the gear know are they mad.... Tried it on the weekend,and got everything out apart from the last nut and bolt on the very underneath of the gear stick it was impossible i in fact gave up...... I also don't think it's that that is causing the wobble. It could be the whole plate with the large rubber mount in the middle,the one where the bolt comes out of that might just be old as it doesn't seem to hold rigid enough. Either that or i need to replace any gear box mounts....... Also i was speaking with Vijay about idling and he suggested cleaning it out with …

Hello again folks, Well my car is still smoking after doing the PCV valves so I guess its likely to be the dreaded turbos after all. Before I go and get the engine pulled and the turbos replaced is there anything else that could be causing the smoke. It definetely has an oily smell to it and a tinge of blue although to be honest I'd say it is mostly white / grey. I'm not losing any water either. Could it be the bores / rings (oh my god expensive !!) and would a compression test show this up? Currently researching garages and prices for turbo replacement in my local area but the bills gonna be big thats for sure. The car only smokes at idle and I n…

I saw a lovely low mileage Zed at the weekend that would be my dream replacement to my current mega milage old timer. She looks great from the exterior and interior. A decent test drive showed that the engine and gearbox are silky smooth with plenty of turbo boost and no vacuum leaks. Then I opened the bonnet which showed some issues that give me a number of misgivingings about her. i) Both wings, front bumper, air filter panel and the frame to which the bonnet is attached have paint showing that indicates they have been replaced my parts from another Zed. ii) One of the original welds has been replaced by a very poor quality weld as you face the front of the c…

Had my car remapped on Wednesday & everything was fine, boosted well up to 1.3 bar, pulled fine with no flat spots right up to 7200rpm. However yesterday it drove like a bag of $hite again with a horrendous flat spot after 6000 rpm in 2nd and detting at the top end of 3rd AAAAARRRRRGGGGHHHHH:mad: :mad: :mad: Does anyone have any suggestions? cos this is really pi$$ing me off now and I'm starting to consider just getting rid.......:eek: :eek: :eek: :(

I noticed my car has wheel spacers on the front, about 7 or 8mm thick. Did the 300zx import come standard with these spacers ? None on the back though. Cheers John

Hi, I have a annouying vibration at about 40mph, I have mentioned it before and some people suggested it could be a propshaft imbalance or maybe a gearbox mounting. The car is due a service soon and I am wondering how much it might cost to get it fixed. Anyone else know how much it might be roughly?? Also is it likely to cause any longterm damaged leaving it (considering the cheapskate option too ;) ) Cheers Barry

Its my wedding anniversary next weekend and my (American) wife has never been to the south coast. I`d like to whip her to Southampton for he weekend when I get the Zed back from JeffTT on Saturday morning. Can anyone suggest a good hotel in the area? p.s. had to stick this in help and advice as: 1/ It is help that I`m after 2/ my membership has not been confirmed despite mailing my cheque 23 days ago thanks for any help.....I wanna make this special for her.

Zed causing me grief!!!!!!! Doesn't like starting when warm. Fine when cold usually!! The normal 1/2 turn of the key, however if it doesn't catch on that first fire it's usually takes 5-6 seconds before it will start. As for when its warm and after a run, come back to it 1/2 an hour later and it really struggles to fire. when it does start there's a real hesitation and drop of revs as soon as you depress the throttle, not enough to stall if your careful but damn annoying. 2 mins later and they'll be nothing wrong and no hesitation. Theres no hesitation or missing after that initial press of the accelerator, and she pulls like normal. Any ideas!!:conf…

Hi all Just wondering if anyone can throw any light on why my Zed - a 89, jap spec, TT Targa Automatic is doing a very low 13mpg? It used to do at least 19-21 but for some reason has now dropped to 13mpg? Also where can i get good allloys for the car that will def fit the ZEd? Just gt back form ibiza today where it was 42 each day in the shade..its quite cold here then!!!!!!! Regards Ian

Hi All, Found a couple of boost leaks today, one easy, one not so easy:( It's the lower turbo hose which has split - the one with the ribbed/flexi section. I'm assuming this is the outlet side (?) Three questions: 1. Is it possible to replace this hose with engine in place? 2. This is a moderate split, not huge, am I right in thinking this will mean drop in boost pressure, running lean off boost and running rich on boost? 3. Is there an aftermarket replacement part available (Smithy?) - dreading the Nissan price. Still getting some detonation - especially now I've cured one of my boost leaks (not running as rich now I guess). Had a new fuel f…

Hello there folks, I recetly joined the Z club but stilll don't appear as a registered member in my usual ID. Am I missing something? Cheers. Martin.

Just bought a 1993 J-Spec import that came with a indash tv/gps sat nav/cd tape player. The only problem is that I can only receive 1 radio station and the tv tuner doesn't pick up UK stations. The unit is made by pioneer. Does anyone know how to convert these units to UK spec?

Well every so often at the moment the engine temp guage (OEM) is going rather high. I recently did a clean out of sensor sender as guage was going erratic. The elect. fan is working. When air con. is on temp. goes up more. Questions: Could it be due to the extreme hot weather conditions? New exhausts were put on and I did notice that the idle rpm is slightly up - around 1 instead of below which could lead to overheating. When I noticed this I thought perhaps the ECU needs resetting - so undid battery etc. but the idle RPM may be still higher than should be - would ECU reset help redo idle? Anyway the wife is out in the ZX at moment and I've told her …

anyone know what wires I need to connect to? According to the wiring diagram: white = +12V then i need IG1 output & IG2 output, now do these correspond to the black/white & black/red wires on the back of the ignition switch? For an APEXI timer by the way..... Thanks Jon... :)

Hello there folks, I;ve checked the small print on my warranty policy and found that the turbos are only covered if they6 fail suddenly rather than by wear and tear. All this means I'm actually contemplating changing them myself. I'm not kidding myself in that I know its a mammoth job. I know its possible to do it with the engine in-situ and this is the way I'll have to try it as I don't have any way or removing the engine. Has anyone done this? Annoyed with myself more than anything as I should have checked the policy more thoroughly. Cheers. Martin.

I just replaced the rear transmission mount on my 1992 import auto n/a. The old one looked ok though, no splits in the rubber, seemed soft enough. When they deteriorate can you tell by looking at it ? Has anyone replaced theirs and the old one looked knackered ? Thanks John
