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…

Anyone got a spare zx user manual for a JAP spec auto, Fairlady - or as my work coleagues call it - with much hilarity - A Nissan LadyBoy

The exhaust note on this system between 1000 to 3000rpm is a really deep powerful one that breaks windows and sets off car alarms as you drive past. P.S I don't think you could compar any Z exhaust to a Nova or escort etc!! After 3000rpm though the sound goes from nice and deep to a sporty noise that is easily bearable at motorway speeds and the X pipe balancer keeps the exhaust note and flow very even. Finally, you won't find a better quality or more expensive system from the U.S. Check your email NICO ;-) Steve Steve

I am gonna buy one of these cars shortly, I was looking at a 1991 Auto Twin Turbo with about 60k on the clock. I really need your honest opinions guys, are they reliable? I don't want to fork out a load of money on something thats gonna give me problems. Its either a 300zx or a supra TT. I would prefer a Z car though!! Your thoughts are appreciated. Dave

I sell it to someone in the U.S. Basically, the B&B is known as the loudest s/s system on the U.S market and it really does make the Z sound twice as powerful. It has quad 4.5" oval tips and the X pipe balancer which is recognised for maximum flow. This cost me over £1000 incl vat, duty and I'll sell it now for £500. Steve

Had my AVC-R fitted today by Bob (cheers mate!). Wondering what you 5-speed owners have used for your settings. I have preset 1.05 mm/Hg, with 68% duty, I have set gear based boost for 3rd gear onwards. 1st & 2nd gear is being taken care of with rpm-based boost (Ne1 @ 2500, Ne2 @ 3000) I have increased the duty on these two rpm bands to 70% to give some extra oomph at low revs in an attempt to reduce spool-up time. Is this ok, or am I totally way-off with my understanding of how this thing works? Dave

Here's the deal, I have an HKS filter in very good nick and I want some stock rear wheels. Part exchange? Cash? Swap? Bill

So what happened ? What sort of Zs were there ?

Hi all (my first post), I'm shortly hoping to purchase a 300zx. I want a Twin Turbo auto and it's going to be an early model (probably imported). Are there any specifics I should look for/be wary of? I intend taking out a 12-24 month warranty (to cover turbo as well). Does anyone have any info on warranties to avoid (don't want any PITA "don't cover that" conversations with insurance agents!). Seems most of the imports are cloth, I'm waiting on some info for recovering the coachwork in leather but it doesn't seem to be materialising, anyone else have any contacts? Enuff questions already, Cheers.

Hi, does anyone know were I can get a replacement button for the aircon pod for my jap tt as the button for the windscreen has suddenly vanished, not sure whether its aliens or a government conspiracy :-)

Hi everyone. Here's my first post on this new forum. Anyway, I found the following page and thought that some of you guys make like to use it: http://toy4two.home.mindspring.com/tire.html Andy

My clutch is at times seeming to sick causing the engine to rev when at 3500 revs, instead of putting the power down is this the clutch or another problem. I've only been a owner for 4 weeks its a little bit new. If it is the clutch can any one suggest a good garage for a new one Cheers John

You may recall the power light flasing problem, well I don't think it is anything to do with the Auto Transmission. The problem is now more frequent. The car is fine until a shortish journey and the speedo will drop from 40mph to the stop. When it does this the power steering packs up which is quite alarming. The Speedo picks up after 40mph and all is well. Question. Does anyone know where the sensor for the speedo is? Does this fail? Can contacts be cleaned? I think the 16 flashes of the power light are telling me that the speed sensor is buggered. Anyone had this problem? Simon Pass 90 300ZXTT

Hi: Can anyone recommend a decent window mounted (ala demist type) ariel. Want one that wont stick out like a sore thumb when attached to the windscreen but still performs well. Cheers /\/\ark

I have a Jap spec non turbo zx with an automatic box. Can any one tell me what the button 'power/hold' can do for me, and when and where I should use the overdrive. What is the most fuel economic way of using the gear box, and what is the most powerful. cheers, John
