OK for some wierd reason my boost drops from 6.5 to 5 when the car warms up. Every time i try the on board consult it reads 55 i've tried testing it when it looses boost leave the car on then try the test but nothing happens unless i turn the car off then onto just ignition by this times it's re-set itself.... Can anyone tell me why it only looses boost after it gets hot and how i test the ECU on board for code 34 without a laptop??? It can't be the det sensor as Ryan changed it some few months ago i've also check the wiring from the loom to the plug and this is now all fine??? Could it be the wiring back to the ECU or something else? The …

Hi guys! Looking for some advice?Is the oil filter for a TT/UK model the same as a N/a J-Spec?I have a brand new genuine Nissan filter for a TT and would like to use it for my next oil change (soon) on my N/A (94) but need to know if the TT filter fits all blocks before removing the old one? Any advice would be great...Thanx.

after seeing my car my sister wants a 300zx now lol a TT would be to much for her run and handle so a N/A would be the best option see as see has never driven a auto, it has to be a manual what sort of prices do people pay for a mint non turbo manual? thanks Mark

How do I adjust the alternator tension, I've found the bolt but it doesn't seem to do anything!

My oil pipe has burst at the bottom of the radiator and now I need to know if the auto gearbox oil is fed from the same reservoir as the engine oil? How do I adjust the alternator tension, I've found the bolt but it doesn't seem to do anything!

Anyone know if it's possible to get touchup pens from Nissan for colours that weren't available in the country? Ta

hi after buyimg my 300 tt auto i have heard a lot of bad stories about gearbox failure so iam hoping to do a manual swap could anybody tell me of all the parts i will need apart from the obvious (gearbox,pedals) thanx.

As the tittle of the thread says What speeds in what gear.

Bought a Compression tester. Anyone know what the Compression readings should be on the Twin Turbo?

Hi Guys, My name is Les, new to the forum and from Doncaster. I have just bought a newly imported 1991 300zx SWB non turbo in yellow and it needs chips to deristrict and change from kmh to mph, just need a few pointers on where / who to buy them from. I am convert from Porsche 944's and got bladdered at 160 in my 944turbo by a fairlady that just kept going! hence my search began. I like everything about the cars, everything works and no rattles, looking forward to the weekends now! Thanks guys and Kind Regards Les

was it you?

...what do they actually do? I'm guessing they govern some sort of crank case breather system. I have a stalling problem with my car and fluctuating idle/miss. Now if I drive hard, then if I was to come to a halt, depress the clutch, the car would stall. Is this due to PCV valves?

I think my zed is overfueliing quite bad, I havn't found any leaks in the fuel system and the system seems to be pressurised properly. MPg has dropped to around 11 and there is an aura of petrol smell around the car,= when driving, I think i heard the exhaust pop yesterday at about 100mph also. I've recently had new o2s and cats put on. car also idling at 1000rpm and hesitates at times when pulling away, any ideas where to start looking? car is stock boost with stock ecu,

I just thought I would say cheers for all the advice in the last thread I started that has been closed. I have made up my mind that when I have the cash I will be buying a manual TT and it will be my daily driver, Now all i have to do is wait and hope my other half gets a permanent contract soon.........

anyone fitted one of those stick on dash kits on Ebay? My dash is showing signs of wear and tear and this could be a good fix? Are they any good?

Just wondering what the best dump valves are for the 300 and where the best place to get them from is? I need that sound in my life but am aware that its going to be fairly pricey as 2 are required! Also does anyone have any pics of them fitted? Cheers!

does anyone know what spoilers are on the steer from the rear lads zeds

When i got my Z'd it had an aftermarket head unit, nice Panasonic with CD changer. But it looks like it was fitted by a monkey. On closer inspection i found that the usual facia you get with stereos these days was not fitted, i have got it but it won't fit in the slot. There's about a 10mm gap on each side and 5mm top and bottom. I can't even ram the facia in. Anyone else got this problem or am i missing some parts? Ta

guys what is the sensor for in the vent behind the windscreen in the grll passenger side ?? and does anybody know where the fuse for the intermitant wipe is ??? tearing my bloody hair out trying to find it .....

I was replacing the driverside rear speaker yesterday. When i got the speaker out i spotted a strange thing'ie bolted to the inner arch. It was a black box with Clarion printed on it. Anybody know what it might be? I think it's something to do with the sound system cause the original head unit was a Clarion. Ta

I've been told that my aircon needs re-gassing. I read an earlier thread on this subject which describes how to check if the Argon gass level is ok, through a little glass window in a pipe just in front of the battery. I've done this and there appears to be nothing in there. The thread also explained that the standard replacement is R12 and that this is not available any more and that the latest stuff is not compatable. I'm a bit concerned as the car is booked into a specialist on Thursday. Has anyone else had to do this recently - any advice?? Thanks

Hi everyone, I am new to the 300zx scene and have just bought a '92 TT (manual) and have been driving about getting used to it etc. Had a bit of a worry this morning when it wasnt boosting properly but that was only a pipe that had come loose, thankfully. But i am paranoid about every little sound there is and today have noticed a whistly noise at peak boost (standard 0.6 bar). There is a whooshy noise at normal boost anyway but im assuming thats just the HKS filters sucking in, but i havnt noticed the whistly noise until 2day? The boost seems healthy and theres no smoke when boosting so am I being over paranoid or is there cause for concern? I know its difficult wit…

I've seen this beauty twice now on my travels along the M25. It's a silver SWB, parked in a fenced in car park along side the M25 (clockwise) directly before the M4 junction (J15 I think). Aftermarket bodykit and spoiler fitted - looks sweet - anyone here???

Rather different to Yampiedog.... Drove into London last friday and there was a lot of start stop traffic off the M4. Girlfriend said she could smell fish. Resisted the urge to tell her to shut her legs!!! :x: A while later I glanced down at the speedo, noticed the water temp guade wae higher that usual. Took ages to find a place to stop without parking on double yellows. Opened the bonnet and saw water pouring out of the short rubber pipe that runs from the top hard pipe from the rad to the engine. Just below and to the right (as you look at the engine) of the Dashboard water temp sensor. I let it cool down. IN the meantime I went off in search of a garage to g…
