Hi All, I'm about to order an O2 sensor removal socket, it's 22mm, is this the correct size? I can't get my calipers on the nut as the engine is in the car hence cannot measure accurately. It seems all references on here are to 22mm but mine appears a little smaller (illusion?). Not bad for under a tenner http://www.sealey.co.uk/PLPageBuilder.asp?gotonode=ViewProduct&method=mViewProduct&productid=8377 Thanks in advance. RobH

Subject says it all really. I can get the NA sensors no problem, TT is not listed with my supplier. Another reference I've seen (ngk.com.au) lists the same sensor for all models and, presumably, for both sides (unless their partsearch only shows the first entry in their database). Advice appreciated. Cheers RobH

Yep....the noise is detonation. So i've knocked the car back down to safety boost and am now on a fault finding mission. i'm firstly changing large boost pipes for new ones as mine are knackered, re checking the installation of my EBC pipes etc, changing the spark plugs, moving a pressure sensor T Piece from next to the fuel regultor (oops) to further down the line. Im going to flush the coolant and clean the rad as the car runs very hot Will then be into looking at fueling after that. Any other inside info anyone can give me the heads up on ?? I have popped the car on a conzult (thanks Topless!!!!!) and all is fine with the engine sensors etc.

Flashed you on Sunday, very nice looking Zed

Hi , im looking for some advice I'll try and keep this short: I have a 1990 Jap 300zx twin turbo that i bought 3 years ago and i took it off the road just over a year and a half ago as i got the chance to purchase a wide arch kit , vented wings , vented bonnet etc all together and i had spare £s at the time. Anyway now its about a year and half later and im ready to put it on the road again, the car hasnt moved for a year and hasnt even been started for last 8 months since i brought it home from my work (where it had sat for months getting everything fitted + painted) and was wondering if theres anything i should watch out for or check before starting it …

My boss said he saw a black zed with a bright yellow bonnet parked at the roadside in Shepshed. Anyone here? Ivan

Right, I'm going to attempt building my own sub box. I had thought about getting a car audio shop to build me one, but I was always pretty good at carpentry and it's not a complicated shape. Because I have no audio engineering knowledge, I am at a bit of a stumbling block. Really need to know, in essence, what's the key to building something that not only looks good, but also does what it's supposed to and sounds good? Not after a mega system as sounds offs or high street parading aren't really my thing. So a single sub box for my for my 10" pioneer and amp is pretty much all I am after. I can't get the bass definition from my current speakers, even with so…

My new 8 pot brake setup:cry: Any suggestions,when i try to refit wheels the calipers stop the wheel going back due to the inner dimension of the wheel :cry:

Does any one no what this is hidden away under my dash? Am I right in thinking this is the diagnostic connector?

Was it anyone off here. Was parked in Frensham down by Bordon yesterday??

Is it better to use your Zed every day or now and again, I only live a mile away from work, will driving short journeys do more harm than good? I dont push her over 2500 revs, would it be worth getting a cheap runaround? what do you all suggest? The car is too nice not to drive everyday.:D

I have a couple of old series 1 Z seats that I don't have a use for. Anyone know the best way to get rid of them? I don't think the local refuse place take old car parts? Is it a case of paying a car dismantlers money to take them off me?

Hello, Been having this problem for a while now and its getting worse doesent matter if its warm or cold engine but runs better when warm... Just! on tick over the engine revs are up and down and then goes back to normal for a while then same again I could rest foot on gas at 2000rpm and when the lumpiness comes back the revs drop back under 1000rpm even though my foots in same place, when you drive it its fine for a short while between lumpiness and sometimes you can hear some det going on under bonnet. I have replaced the connectors on temp sensor but makes no difference. Anyone got an idea to what it is?? heres a vid of the rev counter,

Apart from Eagle and Carrillo can anybody suggest another company that make forged rods?

Hi All, Slotted my engine back in and got it running. Not running well though. I suspect I have a big boost leak somewhere. Can't pressurise the system enough to find out where - so it must be substantial. I'm sure it's a leak in the turbo / IC circuit having ruled anything after the throttle bodies out. The reason for my post is to see if anyone can suggest anything obvious that I may have overlooked when reinstalling the engine. I've removed the stock recircs and capped off the hardpipes at 4 points, although admittedly I could do with a better solution than I am currently using for this, does anyone make a kit for plugging these annoying orifices? Stock …

Hey guys, after nearly 2 years of muppets wrecking my engine i've finally got my car back... My mechanic has replaced the oil pump, water pump etc. He says that the car is making 2 bar of pressure whether the engine is hot or cold, Anybody got any ideas what the problem is now:( Is it just a new pressure sensor?? Thanks.. Richie

Ive now finally got my zed back on the road thanks to andy p and a new ecu but i still have a slight hesitation when pulling away if you give it more revs its fine. But pulling away normally it will try to die so can any one help me at all buy pluging in a conzult in and having a look at things thanks chris
