Point me in the right direction. Car appears to pull okay but at 4500 rpm just stops pulling and I get the pop of fuel detonating in the exhaust. I do have a blitz boost controller so tend to keep fuelled with the Tesco 99 as that's the best a man can get round these parts. Any idea what may be causing this problem. If its any help I recently had an issue with a leaky oil pipe around the rear diff cooler which has been replace not sure if this has any bearing on.possibly a sensor issue ? Help appreciated

As per above - terrible idle (500-700) and keeps dying when cold. Perfectly normal when warm :)

Can anyone tell me the inside diameter of the recirc pipe that a dump valve would fit to please? Or if anyone has some lying around, measure the fitting, or sell them me nice and cheap? :)

Hi peeps, I'm nearing the end of receiving parts from z1 to finish my engine bottom end rebuild, I'm told I should get new turbos while the engine is out. Do I get the new ball bearing technology or get the housing/impellers replaced (not rebuilding) and use current turbo housing (so good as a new turbo), I've heard trouble with the 360 degree thrust bearings and even a mate has has two failed ones of these from Turbo Technics, going out of my mind of what to do?? I need a four bolt solution and a 2.5" downpipe. Are these ok? http://www.z1motorsports.com/product_info.php?cPath=6_16&products_id=3862 Thanks.

Does anyone know if you can get a fibreglass tailgate and lexan rear screen for the 300? Really like to fit one as it would save a shed load of weight, I had one fitted to my s13, and it unbelievable the weight differance Paul

Talking to ultimateray this evening both of our cars are autos convertted to manual. And we both have high idles when warm around 1500 and 2k with clutch depressed. Looking about it sems in the us they routinly knock down the idle speed after a manual conversion. Is this right and do I still need to do it?

Had a very weird thing happen today. Driving home on a near straight road,my steering wheel points dead ahead and car tracks in a straight line. After about a mile I notice the steering wheel starting to go off centre, car still going straight, after about another half a mile the steering wheel had turned to the left by about two inches, yet the car was still going dead straight and not pulling to either side. I came to a roundabout, went round it onto another straight and steering had returned to normal but then the same thing happened and kept returning all the way home. I haven't got a ****ing clue what's going on, anyone else have a clue? I can on…

Finally got round to fitting the aerial I bought, bit of a struggle but managed in the end. However, nothing happened when I switched my radio on so I thought, sod it, I'll look at it tomorrow but when I switched the radio off, the mast came up?? So, it stays down when the radio is on and comes up when turned off which kinda defeats the purpose of a new aerial! Tell me it's something simple (like me). Cheers folks! Ronnie

Mine are smoking lightly after decatting. Its a pisser but thats life. Ive been given 2 quotes to rebuild one of 190 a side the other over 300 a side. The cheaper being from turbo dynamics. I know I can rebuild myself and get them balanced, the balancing is around 60. So whats my options and whats the deal with 360 bearings? And should I even bother doing a rebuild or would an upgrade be within budget, and worth doing. I onl yh want about 350 to 400 usable horses. My budjet is a max of 600 for a complete job. With the block out il be able to deal with those pesky rocker seals. And renew the turbo oil lines. So lets discuss.

ok had the RAC out to confirm what i already knew ,,,hes checked all cablse and ohms on the injector and came back 40 kilomes and a good one is 9 or .9 i think he said checked the injector cable and thats pulsing ok ,,,so where can i buy a new injector from??

Was thinking of going for the satin black look? I sprayed the rear quater and a bit of the bumper today and i think i liked but would be scarey doing a full car :huh: Has anyone got that pic of the black zed with the scarab bumper. Anyone got any pics of satin black zeds. one thing i will say is it has gone from a classy looking car to an evil one :cool3:

Is there an air filter any where on the car for the ventilation/aicon. system?

No I dont need the mr's seen to haha but I am looking to change my front wheel studs for slightly longer ones as i'm using a 5mm spacer. Can this be done on the car or does the bearing need to come apart? Also anyone recommend a company to get them from? Thanks

Under full throttle my Z has started to judder, slight pauses in acceleration. I gave it a few full throttle runs tonight, and after some gunshot noises, its started to have less judder / pauses in the acceleration, still not perfect though, a flat out 30-100 run now gets 1-2 judders compared to the 5-6 it was having before I did a few extra runs. Its the only time I have really gone full throttle in it to be honest. Thinking there maybe carbon build up or something like that. Hoping its not a missfire. engine runs smooth at all speeds, its just affected under full acceleration. Any advice at all?

A few weeks ago i brought a job lot of Zed parts from a guy. Most of the parts i need but there was a aftermarket rear bumper included which i thought might fit my wide arch zed but sadly dose not. Its quite unusually as its got what looks like a rear diffuser which goes right up under the fuel tank and and a small spoiler section which looks quite smart! I'll gett some pictures up asap but a mate of mine seems to think its a SE nissan rear bumper anyone got any ideas?

Is there anyway of testing a coil pack whilst it's on the bench?

is the only difference in the exhaust system the rear section??

So finished everything off, then double checked it. Went to start the car and click noise and now no power, probably blow something, like a fuse, because I connected something up wrong. Any ideas would be greatly appreciated thanks. :crying:

Since the divorced downpipes the tub has no where to bolt in the top nut on the heatshield so it rattles occasiknally. Can I remove it or will it cook the ecu?

Was thinking of removing front disc sheilds when i fit my big brake kit what sort of a job is involved in removing them.Just thought it would look neater than cutting them down thanks taff :yes:

I dont use my zed very often now but if i leave it say a week or longer it doesnt start staight away takes like 5 to 10 seconds and smokes a bit misses a bit then fine after that doesnt smoke on idle and starts fine durring the day and next morning .just when left for long periods it does this does anyone know what it is or is this ok thanks taff.:yes:

Hi all, I'm waiting to hear back from Jeff on this problem, but I would appreciate any advice you could give me from your own personal experiences, etc. I have an engine misfire caused by a cylinder not firing. I've isolated which cylinder has the issue by having the engine tick over and unplugging one coil pack at a time. When this coil pack is unplugged there is no difference in engine speed. We also noticed that jiggling the harness holding all of the cables at various points altered the engine speed. This suggests to me there is cable damage and connection problems. Not sure it's advisable driving from Portsmouth to Zedworld like this! …

I'm the only member of our family without an i-phone but I want one now :biggrin: http://www.ebay.co.uk/itm/Iphone-4-4s-Case-Metal-Aluminum-Hard-Back-Case-Cover-300ZX-350Z-370Z-FAIRLADY-Z-/160852211177?pt=Apparel_Merchandise&var=&hash=item257389f5e9#ht_1054wt_932 £19 each is a bit expensive unless a group buy is arranged :yes:

i've recently had a little problem when starting the zed. it fires up without a problem but after about 10 15 seconds the idle drops to about 300 until i give it a few revs. I've also found that when this happens, if i turn the engine off and then on again it runs fine. anyone got any idea on what could be causing this? by the way its a n/a if that makes any difference.

after any opinion form anyone with them really, changing my autobox and im putting another order in with z1 though i might get them, six-shooter engine mounts and solid transmission mount i like the idea of the engine being part of the chassis and less movement, but surely Nissan would not have used rubber if they weren't important??? road noise vibrations etc don't bother me, my zed stupidly anti-social anyway. :shifty:
