Hey all, Quick Q, Was sitting in the Z last night, Sobbing heavily at still not having fixed her after 6 months now. Well i was tinkering with a few things and noticed when you switch the ignition to Accesory mode(the last setting before ignition) , the boost guage needle reads abot 2psi, which is the same as the absolute peak boost im gettin at the momment :o(( I was just wondering what the normal reading for this is. Probably a calibration error in the boost guage somewhere, however it seems a little strange, probably just coincidence i guess. Cheers Z ya Nico91TT

When I got my Zed 2 years ago you would rarely see one. Just recently though I've seen hundreds of them! Most Jap imports (Square rear number plates are a dead giveaway!) The japs must have few left in the domestic market. I wonder what the official figures are for these cars now? Must more than were ever officially imported now even after 10 years of smash ups. (Mostly by Steve E!!!) ;-) Simon

Finally getting the Speed sensor replaced on Saturday, I've got used to no power steering so lots of oversteer to come. Q Where abouts on the gearbox is the sensor? Can it be accessed from the underneath of the car? Can the job be done while you wait? The bloke at the garage does not know where it is but seems to think its a while you wait job. How long am I gonna wait? Advice appreciated. Simon 90 300ZXtt Jap import Auto

Following my previous run in with a solid object I've now joined Jez, Dave, Rowan and Jools with Race Logic Traction Control. Purely from a safety point of view this has to be awarded 10/10 and then when you consider tyre wear I might get more than 4000miles out of my rear Pirelli's. I've yet to see a bad word said about it!! Steve

This goes 4 U 2 Steve... Really dumb - BUT - when I upgraded my brakes (AP 6Pots & Discs) I didnt stop to think how the hell I was gonna squeeze them behind that pathetic little pram wheel of a spare - that is until today! So... the Z had a nice little trip home from work on the back of a flat bed today! CHRIST! /\/\ark

I'm thinking of replacing my OEM air filter with those cotton gauze types eg K&N./Green? etc. Is this a good idea ? Do any of you who've done this get better performance / mpg ? Is it easy to install ? Any advice appreciated. Thanks William Flint (Auto 300ZX-TT-Jap spec-1992)

I have just had my auto box rebuilt and I am not happy with the gear change at high revs. There is a lot of hesitaion and delay. Does anyone have the same problem? I am trying to find another Z owner with an auto box that is in good working order. I would like to ride passenger so I can compare it to mine - before I go back to the garage and reveal my unhappiness. I would appreciate any help with this. I am from the Swindon (Wilshire) area and are prepared to travel within reason. I have a 1990 TT (jap spec) Thanks, Andy

Hi, Just 1 question. I'm going to install the HKS EVC4 Boost controller and need some extra 6mm Vacuum Hose. I have been told that I can use 6mm Fuel Hose as well and it is the same type of hose. Is this correct ? Any info appreciated.

Not the best turnout ever from the forum today but Steve E & I did our best. And Steve's best was considerably better than mine as he hit 13.5s on the first strip outing for his new baby. Personally I couldn't better 14.8 which was disappointing after low 14s last time. On the way home I noticed my boost has dropped a bit which may well explain things. There were a fair few Twin Turbos there, the quickest being Malcolm (for those that don't know him he's got a bottle of laughing gas in the boot). His best before I left was a 13.3 although that was disappointing for him as he has been in the 12s before. See you all next time ! Dave

Can anyone tell me the logistics of converting a Jap spec Autobox, to a 5 speed manual? Anyone ever done it/seen it done? And how much does/would it cost. Cheers, John yippie its Friday !!

A friend and I are going to try and connect my HKS SLD (thanks Simon!) tomorrow evening. The instructions I had faxed to me from HKS UK are useful, but I want to be sure that I'm connecting the unit to the correct wire. The Power and ground are OK and I'm fairly certain I need to cut the speed sensor wire and route this through the SLD. Is this correct? If so what colour is the speed sensor wire? Thanks

Hi, What do you think of these costs for a service and cam belt change: - Cam-belt change (inc Parts & Labour) = £290 (inc VAT) Recommended service for 55,000 miles: - B service (Labour) = £165 inc VAT - 6 spark plugs = £70 inc VAT Is this a good price from a Nissan dealership ? Thanks.

Okay people, here are some ideas for our next meeting. Dates : Sat 9th and Sun 10th Septmeber Events : Firstly, Bob has agreed to come down for the weekend, and has offered his services for anyone who wants any Alarm or ICE work doing. So if you have any requirements, such as immobilisers, speakers, etc, then tag them onto this post, or mail Bob directly and he can get an idea of how to schedule the work over the weekend. The venue for this will be my house in Sutton, details nearer the time. Secondly, is anyone interested in a couple of hours go karting over that weekend ? There is an indoor kart track at Streatham, which has two time s…

I am looking at buying a SWB Manual off a friend ho imports jap cars. He has run it himself for a year because he loves it but wants a Skyline (due to luggage space). He wants £5995 for it, sound like a fair price for a SWB Man 90 on an H? It seems to be running VERY rich, petrol smell from exhausts on startup but no smoke, seems to be slightly sluggish as well (not normal 300ZX g's on right foot application! Also the speedo seems to over-read by about 25% and apparently the 4 wheel steering also thinks the car is going faster than it is? I am puzzled and a tad worried about buying it. Any suggestions on cures would be very helpful, also advice on SWB Manuals if an…

I was looking at converting my Jap spec speedo from 180 KPH to 180 MPH until I found out how it is done. The convertor works by using a two thirds ratio so the speedo will register 2/3 of what the speed sensor sends it. The conversion from miles to kilometers is 1 Mile = 1.609344 KM 1 KM = 0.6213712 Mile So the conversion is off about 7%. Here is a table of how fast you are actually going at various speedo readings. 30 MPH Speedo = 45 KPH = 27.96 MPH Actual 50 MPH Speedo = 75 KPH = 46.60 MPH Actual 70 MPH Speedo = 105 KPH = 65.24 MPH Actual 100 MPH Speedo = 150 KPH = 93.21 MPH Actual 150 MPH Speedo = 225 KPH = 139.80 MPH Actual …

Im due to have my turbo's serviced in september at Silvia eng, also having them slightly breathed on :-). Can anyone tell me what other things would be good to change/service whilst the engines out. Already planning on having the water pump, and fan belts changed, cam belt recently done. Thanks for any advice.

Hi all, I just purchased the HKS EVC4 boost controller. It looks pretty complex to do yourself and I was wondering if anyone here has had experience fitting this or any other boost controller ? Where can I take my car for this installatio n ? and what sort of price would they charge for fitting ? Any tips appreciated. Thanks.

Does anyone know the date of the Drag Racing at North Weald, I think it's sometime this month and is anyone going (I missed the last one)

Hi, I have a 1992 NA and am planning to do a lot of repairs and upgrades in the next three months. Instead of posting serveral messages I will just ask several questions in this one. 1. Does anyone know where a AC compressor is for sale in the UK? 2. Are there any mechanics who work on Z's around Cambridge? 3. Is there any body shop you would recommend for installing a Wings West body kit? If you are interested I know where to get the whole kit for £550 including shipping. 4. My speedometer only goes to 110 MPH, how can I fix this. 5. My car beeps over 68MPH? How do I fix this? 6. Can you recommend anyone to look at a vibration…

I have some problems getting my Camp system to show the actual speed. Usually it shows 0 km/h, sometimes it will show 500 km/h and sometimes it shows whatever it feel like. I have hooked it up to the yellow/green wire in the ECU, should be correct. I have run ECU diagnostics, no errors. Yesterday I checked that there is a signal going from the Ecu to the Camp system. The Amp was 2,61 A when standing still. Anyone got any suggestions? I will try to take the amp meter for a drive and see if the amp changes when the speed change, but other than that I am out of suggestions.

Made a couple of small changes to my site including pics of the AP Racing disks + pics of my 'boot install' !!! (that's a joke by the way - doesn't come close to what Bob would call an install !). www.davehairs.freeserve.co.uk D

You've seen it on just about every car movie, that perfect launch where the rear wheels light up for a second, the rear end of the car slews to the left or right and then f**ks off in a real hurry... well I was demoing the Racelogic system to a customer today and I got it to happen. I really wanted to impress the dude but I knew that my clutch wouldn't withstand the full hard cut 5.5k rpm 5psi boost launch, and I'd already showed him the 4k soft cut launch which the car kinda bogged on. Well to seal it I warned him that "the clutch would probably let go but I'll show you what a real launch is like" Lining it up on a smooth patch of road I flicked the dial up to the h…

Have any of you ever been involved in hiring a cirucit before or know any contacts? I'm just starting to look into it... My initial ideas are: Invite all Z cars, 300ZX, 280, 260 240 etc. Possibably invite other supercars to keep the price down. 2/3 circuit instructors. Hire for whole day. Maximum track price each £40. My first phone call resulted in £4465 for the Goodwood circuit alone! which would require over 100 people. Anyhow I'll be looking into more cost effective, less popular circuits too. Jez.

After going to the bother of working out the UK vs US costs for stock Nissan parts, I thought I'd post them on the fourm: The US is a good source for stock Nissan parts (but, obviously not heavy ones like the gear box!): UK price = £Cost * 17.5% US price = $Cost / 1.5 + 10% + 5% + 17.5% (1.5 = current ex-rate, 10% postage guess, 5% Duty, 17.5% VAT) O-ring : UK £16.22 US £8.58 O-ring top gasket: UK £ 4.23 US £2.06 PCV Valve UK £42.54 US £.6.22 Fuel hose(fliter>rail) UK £30.90 US £19.55 Fuel Filter UK £11.52 US? UK total : £93.88 - US total £36.42 (totals without Fuel fi…
