I'm also got jet black tailpipes which I suppose must be down to her running rich. I know that she is running rich because of a rolling road test after I had the cats gutted recently when they collapsed. I'm pretty sure that they must be knackered becuase they are the originals and she has now done 175,000 miles. Conzult seems to show that with each sensor the voltage often sticks at the same value for quite some time when taken out on the road. So, is it a reasonable DIY job to change the sensors from the top of the engine and can you use non Nissan ones (I never entrirely trust the faqs on twinturbo.net since the engine compartment layout isn't quite the same …

Craig, The time is wrong on these posts mate. Stuart

Can anyone suggest somewhere close-ish to Newbury where i can get me auto TT tuned, fitted 1mm boost jets at the weekend and the car is running sweet but at about 2k RPM there is a noise not sure if it is pinking as its so quiet then completely go's once you give a little more throttle

My tail pipes are black and looking a bit sorry for themselves, was looking at some silver tail pipe trims in Halfords, but they don't do them big enough, only go up to 54mm not the 60mm I need. Tried everwhere, ........ does anyone know where I can get some to fit the Z....?

Hi All, Got most of the parts I need for a conversion now and just wondered about a couple of things... Is there a definative 'how to' on the conversion available anywhere?? I've done the usual searches and come up with very little. Can I use the standard Auto braking components (master cylinder etc) or do I need some more bits from a manual?? I have the manual pedal box. Will I have to get a new/replacement spigot bush? Cheers!! RobH

My car's about due a new set of plugs, and I was wondering about going to a slightly colder plug seeing as it's tuned a bit. Anyone tried running 7 grade plugs (Thinking NGK BPR7EIX-11 Iridium).

Had a slight accident collecting my new car at Dover Docks can anyone recommend anyone? I hear Darren is busy these days??:confused:

Hi all, newbie on the block. I have just today bought my first 300zx... and I haven't stoped grinning since I picked it up !!!! It's a '91 Jap import, 2 seater (not 2+2) manual. The only mods I can determine are a dump valve, and 3 spoke alloys. Body work is in near mint condition, inside a few missing bits and pieces, which leads me to a question: Anybody know the best (and cheapest) place to get replacement switches/buttons for the dash? Also the handle on the drivers seat to move the seat-back forward has snaped off. And finally the fog light bulbs have gone. Can I replace these with the usual lights, or do Jap imports have different spec's? …

Probably a no brainer this one, but it ain't in the handbook... The LIGHTS warning light on the dash, illuminates when the lights are on. They all look ok, except one side light is a bit dim. Is this what the warning is referring too? Didn't know it could monitor light bulbs too!

What do you think is the best path to go down with upgrading brakes? The previous owner of my z has had a boost upgrade (14psi) but left it on standard brakes, which has (no surprise) warped the discs. If I put 6 pot calipers on the front, will the front calipers fit the rear mounting (and discs?) And is the Skyline upgrade all four corners, is it pretty much a straight swap (I should have plenty of wheel clearance with the rims I have), and are they fairly easy to pick up?

would like to know where i can get a km to mph chip from. also how easy is it to fit?? do i have to change my speedo? thanks Andy H

While i'm on about my running problem i've also noticed an oil leak possibly coming from the back of the drivers side cam shaft, can this be fixed without takeing the plenum off? Hope so,if how? Ken ;)

I have never had any whistler from my car, however while driving in Epping yesterday evening, I was follwing three cars doing about 55mph (don't worry it was a 60mph zone ) . The next thing I know this large rock (part of a pavement kerb) appeared in the road, the other cars went stright over it without a problem. unfortunatley my car is a fair bit lower than theirs. I hit the rock and dragged it under the car for about 50 meters until I stopped. I had to jack the car up slightly to get it out from underneath the car (it was wedged). Now I also have a whistle while accelerating, seems to happen from about 3.5k rpm onwards it's loudest in first gear. Have I got a boost lea…

To all, Just re-registerd in my old name i had before this forum was updated, forgot my pessward, Blow me is a mate of mine so from now on i will be myself. Great to be back. Ken :)

Dont usually use the Z when it is bad weather but my last tankfull only made 200 miles before a refill. Calculated 15 mpg! I guess the cold and short journeys is the problem as it otherwise runs great. I even changed those fuel pipes that leak last weekend. Anybody getting good consumption right now?

All wight .... got another we question ! is there any reason why i cannot straight pipe my ZX, is it possible to get a custom made exhaust from the front to back, i have new rear boxes on, these would do for silensing enough. i know that turbos are a very good source of silencing as well.... but what about emissions ? , the car is a 92 tt uk car... so it is before the tight emmissions started in 95 ?...... i could simply remove the air comopressor thing that blows ait into the cats ? Cheers Scottieee :)

Hi people, can any1 help, i just fitted my blitz boost controller yesterday and when i went for a couple of test runs, the sound became quite apparant! its like as if the turbos cant handle the boost, when the boost is building up it sounds rather like a whiny kind whistle or something. but as i gradually pick up it changes to something like a 'large bucket, being jet sprayed'...if that makes sense:confused: running less then 1bar, gain 6 ratio 45... what ya recken fellas? jaz

This is one very unhappy bunny,Went to get into my car yesterday and i couldnt belive my eyes some TWAT has smashed the F**K out of my baby they have smashed the passenger side window through put two great hols in the windscreen and to top it off hit the passenger door with a hammer or summing i am so pissed off and it was my BDAY yesterday and spent all day hoovering the glass up and driving all the way to kent to pick some glass up HAPPY BIRTHDAY MARC!!!!!:mad: :mad: :mad: :mad: :mad: :mad: :mad: :mad:

Are my brakes OK? All the calipers are less than 2 years old, and so are the discs. If I lightly apply the brakes, and then suddenly press very hard, the car stops very well and the brakes really bind. If I am driving and then I slam on the brakes as hard as I can straight away, the brakes dont work as well and its seems to take a moment for the brakes to react. Is anything wrong? I am going to fush out and put fresh stuff in. Could bad fluid cause this? Stuart

Hi, I may be in the market for one of these, if you have a good one give me a ring or drop me an email! Mha5208164@aol.com or 0777 6426 539 Mark

Does anyone know the power out put of a Nissan Skyline GTS-T

Just looking at http://www.dvla-som.co.uk and J300 BAD is only £250 including the £80 transfer! -you can tell I didn't go out tonight and am bored!

Brake pedal is harder to depress than usual and Z is not slowly down as quick as it should! Any ideas? D UK

i posted a while back about a little gadget i got off my mate which measures 0-60 times, 1/4 mile, RW BHP & G-force. heres the website if anyones interested : Tesla G tech i havnt done 1/4 mile or bhp yet (as i didnt know how to till i read the instructions on their site!) but will do once we get some decent weather! :cool:

Hi all, a while ago I posted up a question about my rather failed and dead zed.. got reassured by everybody that I need to remove some bits and clean them, then pop them back in again.. basically sounds like an electronics problem.. doesn't appear to be firing on all cylinders.. heavy shaking from the engine etc. I've finally come back from being flung to the four corners of the earth for work.. (car's batt is dead but soon fix that!).. I know flip all about the goings on under my bonnet, and I've had a look at the Service manual and I don't see which bits of the ignition coils are going to be corroded... could anybody give me a hand one morning or afternoon.. when…
