I cant really think of a way without having a huge cheese wedge shape box in my boot? Please post some pics for me! Thanks for any help - Mike

Just a quicky. Along the drivers side plenum chamber there is two thin metal tubes with rubber pipes going to the throttle body (just behind the butterfly valves) and somewhere else. Whilst fixing car I took the little pipe that goes down to the drivers side intake pipe and also the other little pipe off. Trouble is I can't remember which pipe goes to which tube. Can someone please have a quick look and let me know. Doesn't seem to make any difference in running either way round.

This isn't a new problem, I've just noticed its not coming from where I thought it was originally. I was going over my engine bay today looking for PCV hoses that I have yet to fit and I thought id have a listen for the noise. Basically its a shrill noise at 1.5k and at 2.5k coming from the drivers side of the engine, its been there for 18months and I have no smoke on that side. My left bank smokes at Idle but we have pretty much narrowed it down to PCV hoses (thanks to duffer and smw1). Could it be a dodgy injector? after about 2 miles and once the engine is warmed up the noise dissapears and only reapears the follwing day when left toit over night. I only n…

Hi guys, need to call upon your knowlege again please. I am going to replace the super chip ecu soon with a JWT, what boost can I safely run with the JWT chip? The car is standard apart from the super chip and air filter. Also, I have noticed that some people using a SE chip, is this better than JWT? What are the differances? Thanks.

1.Is it difficult to change the wheel studs? two of them decided to join the great scrapyard in the sky. 2. what are the dimensions of the rear speakers ?

I know its been asked before & I will get called thick to put it mildly! With the evenings drawing in! So can I just simply buy and replace my 55 Watt bulbs to 100 Watts without blowing anything up or burning any wires out!! And if its that simple why the Fxxx dont they fit them in the first place? Arthur:p

I was going to change the auto transmission fluid this weekend. I was wondering if anyone knows if the Jap (mine) pan gasket is the same as the UK gasket ? (In case I get blank looks from the local Nissan dealer) Is there anything else I should buy while Im there ? Thanks John

Hi y'all, I am looking for a photo from the front or front quarter of a silver ZX with OEM bumper (not 99 spec JDM) and number plate in UK position and matt black stripe filling in the gap between the sidelights (as stock). For example: this is "wrong": Because although the bumper is stock spec, the number plate is too low (dangling down when it "should" be between the sidelights) and the space between the sidelights "should" be matt black. Pics or links gratefully received. TIA - Gio

The alloys that i'm looking at are blitz 03's very nice but they are advertised as fitting NISSAN SKYLINE/TOYOTA SUPRA/LEXUS 300, now i thought skylines have the same fitting etc at 300's but i didnt know about the supra?? So wheels that fit a supra also fit a 300?? I dont want to buy them and find out they dont fit :rolleyes: Cheers Kirbz

Just done ECU diag as i have a misfire on centre cylinder of left bank and i get code 21. what should i do next??? cheerz zedhot:cry:

Just in the process of replacing the heater matrix at the moment on my manual, (what a twat of a job!) Anyway, the carpets pretty damp and stinking of coolant. Could just give it a clean but I thought it could be an opertunity to fit a new one... Has anyone attemted, and succesfully cut a carpet to fit. I guess this would be tricky beacause of the shape, or know of where I could by a Pre- shaped one. Am after a cream colour. Thanks Andy

Can any of you guys give me some advice regarding oil coolers? It's for both engine oil and gearbox oil? Obviously not with the same cooler... Prices, fitment etc... Cheers Ben

Why is it that when I try to get on the 200SX site I get fookin Fiestas! WTF Try clicking on http://www.sxoc.co.uk/ :mad:

Can anyone tell me how I can test the rich/lean mixture to see if I have it set right? Seems to be smelling a bit (and I really am going through petrol! - yes I KNOW! Who Isn't!) I'm told I can buy a dial to show the mix real time, but is there an easier way?

Just had some luvlie new backboxes fitted courtesy of Mark at Tube Torque, Macclesfield. He pointed out to me that the balance pipes off the back of the turbos have been disconnected, presumably when the original s/s exhaust was fitted. He advised that they should be re-fitted and gave me a few reasons why. But, I'm sure I've heard other saying why they are better left off. Any thoughts?

Finnaly got my zed running again after a couple of weeks of problems, but it's running rough as hell... It happens throughout rev range, and is almost put - putting!! I've searched and found a few similar problems, but nothing quite the same!? ECU's only got fault code for temp sender (which it had before), so this shouldn;t be the cause!! Anyone any ideas? I've replaced the spark plugs, and at some point PTU, CAS and soldered the TPS in an attempt to track down probs. I've cleaned all connectors in sight and checked hoses! How do i check the injectors?? (i've turned the CAS with the ignition on, and they are firing, but i don't know how well etc... …
