Hi I have a continueing problem with water loss and cannot find the leak. I can see water all over the left hand side of the car at the front after driving it, but when I leave it just ticking over at the garage then their is no sign of the leak. Does anyone have any suggestions as at the moment I appear to be stuck. The next plan is to replace the bottom hose and radiator but this may be a little extreme. Could somebody also confirm the position of the water pump and describe the look / position of the coolant pressure release valve. I don't think its the release valve, but does anyone know how to check it. Besides the leak the fans and thermostat appear to be worki…

There's a link to some pics from Le Mans on my site now (www.davehairs.freeserve.co.uk). Not much of the race yet but I'm waiting for pictures to be developed and will add / change them as I can. D

What I've heard is that Greddy fits best. Then there's also a price issue. Anybody know a good place to get them for a fair price? Thanks in advance for your thoughts. BTW, check out my home page for some new pictures from the Holland meeting! Maciek [www.z-car.net]

Some of you might have seen this on Z32, posted by SeedyRom, Apparently that is the back rear quater of the new 2003Z it is pretty much final appart from a few cosmetics that are still open to review. The Engine that is going in it is apparently he NA VQC engine that will be a hybrid of the versions that are allready in the Maxima and Pathfinder in the states : IMO this is pretty disaspointing, i would sooner have seen the Skyline RB26DETT like some of the Japanes have started putting in their Z32's : :o)))) Apparently Nissan Assure us that the engine will put out 300bhp, but what sorta tuning options are we going to be left…

Hi guys, I thought I'd post this discussion I had with Jim at JWT and SGP last night, about what my next options are after my AVC-R install... (yep - it's cut for an email to Viking) Feel free to comment, correct me, hang me, shoot me as required..... > Yep, 1400 is the quote I got from SGP - only asking!!!!! > > So what fuel are you running when you get 18psi... 95 euro or 98 euro super? > I had a really long chat with JWT and SGP last night about what boost I can > safely run and what my next options are... it's pretty much like I > expected.... upto 13.5 psi on stock turbos/injectors/fuel and pop.

Interested to know about what you think of your systems... Rowan

Over in Holland I was told it's 14.7psi to 1bar. (I used this in order to set-up my AVC-R)... is this correct... After reading pages such as "http://robrobinette.com/boost_avc_r_install.htm vvvv" and seeing ... "the conversion to PSI is 14.22:1 NOT 14.5 or 14.7 or anything else." it makes me wonder. I assume 1Bar in the UK is the same as 1Bar in Japan and the US! Jez!

Well, another issue has surfaced. Since I fitted the ECU I noticed that the speedo dies below 10mph and sits there until you gain speed and the needle catches up again. Is this run by the ECU?

Hi thanks for the reply to the previous post, I have now managed to get it to leak again with the under guard removed the engine temperature comes up and stays normal without rising, even when stationary (the electric fan cuts in) so I think the thermostat is probably functioning as well as the electric switch. However I can now see water dripping onto and running down the passenger side intercooler/pipes. Am I right in thinking that the one radiator hose returns along the bottom of the rad to the passenger side of the engine, or could this still be the pressure relief valve and if so how do you find it/ check it. The amount of water loss was about 1 fluid ounce after …

Hi, here are other pics from the real good Holland meeting. (Hi Steve and Tom ;-)) http://www.z32.de/cgi-bin/forum.cgi Bye, Peter

Well, I finally took the plunge and bought a pair of Focal 5" subs to see if I could get some decent sounds in the back of a 300ZX and still keep enough space for a suitcase! (in case I take a repeat trip to Italy with the other half this year). I'm hoping that despite their small size, they will actually make some noise - if not, that's £300 down the drain.....................will keep you guys posted!

Hi, I don't know if anyone else has experienced this but here goes, I took the car out for a spin (Nice Weather), and just before arriving home I noticed the temperature gauge start to rise awfully quick and made it home just as it passed "H". Having looked at the car I can see signs of water/anti freeze around the passenger side wheel arch and under the car on that side. It took about four pints to refill the system. Today I got the car warm and took it to the garage around the corner and put it up on the ramp removed the underguard and studied the car but there is no sign of a leak today. Does anyone have any ideas? Cheers

Anyone know how to diagnose which wheel sensor is faulty, so I can get rid of this damn warning light,its begining to bug me although it is useful as a reading light when its dark:-) Cheers

Don't laugh.But where is the engine oil dipstick.I have a 1993 jap import and its not where the english manual says it is.

My speakers are rasping like hell so are obviously buggered after 10 years of listening to Rolf Harris's 'Two Little boys' at Full volume. What stock speakers can I buy from somewhere shite like Halfords as a direct replacement? I'm not a MAX Power reader so I'm not too bothered about shaking the windows, just want raspless Rolf! Simon

BTW Nico, ran the ECU diagnostic before and after and got 55 (All is well) so looks like there is nowt wrong. I Would still appreciate it tho if someone would look in the user manual and let me know if it says owt about the power light flashing once you fire the car up. Simon

I managed to fit the ECU tonight and got the lot done including jets before it got dark. ECU was easy despite having to remove an HKS SLD that was fitted for me when I got the car. Pretty easy though as the fitter had used connectors to reverse the job easily, good man. What a bastard getting the old hoses off though! Christ my knuckles have no skin left! So all fitted up, test all clamps and hoses, drop the lid, put tools away, wash hands, lock door. Spark car up, all well and good. Roll car onto road take it very easy till the car warms up then head towards the M3. Hit lights just before motorway. Goes Green, hit the loud pedal. JESUS CHRIST ON A BIC…

Took my Z to the Nissan dealer today to get my ACT clutch fitted. Unfortunately some manifold bolt sheared off, so they had to drill it out. The result is, my Z won't be ready until tomorrow- they lent me a Micra 1.0; somebody please shoot me! :o(

And where can I get a good deal? I would want them to be fully tested, I do not want the chance of installed a faultly injector? Advice please.

(Forget the price - for now) After speaking to Steve, one is deeper and the other has a wider intake, but could be blocked slightly by the stock 300 intercooler intake holes. Any proven results?

Fellow JWT'ers. If I have stock gauges and the JWT/POP upgrade should I avoid full boost for prolonged times? What other cautions should I take? This is my only transport at the moment so I don't want to feck it!!! Is an HKS Super Drager/JWT+Boost jets a stage 2 or 3? Simon Pass

It says in the destructions for the POP ugrade that comes with the JWT that "The boost must be checked with an accurate gauge to determine whether the boost pressure is in the range (12-14lbs). If the boost is too high 'Ping' or detonation may occur Jets can be ordered to correct high or low's" Question. Should I get my boost checked after install? If so, who knows a boost gauge owner in the Berks area? Simon (Ecu sat on desk waiting for Saturdays spanner session!!!!!!!)

I'm thinking of ordering some parts for my Z. If anyone has used SGP what did you think?? Also, does anyone know the temperature limit on nissan pads and discs? I'm asking because my front passenger side pad has cracked and scored the disc big time!! Thanks, Trey.

This morning I started the car after it being idle for 2 days. Rather than starting first click as usual it took a few throws to start and then fired and less than all cylinders for a few minutes. It was OK after it got moving. This is not the first time this has happened. It had a 3000 mile service last thursday and had new plugs at the last 12000 service. Any ideas on this. Fouling plugs? Was OK on the way home tonight. Spooky! Simon P.S. Got card from posty, chip at post-office. One day it will get to me!!!!!!
