Fitting my big brake setup and managed to do the fronts easy enough but having issues with the back. The biggest being the brake dust shield for the OEM brakes. As you need the inner part of the shield for the handbrake what does everyone do in terms of separating the shield or trimming it back ? Its looks spot welded so i'm presuming you just drill out the welds or do people just cut off the larger piece ?

So, was finally hoping to see my knock sensor today, stripped down everything to get the lower intake off, didn't realise what a nightmare it would be to get the timing belt cover off! Anyway, got everything freed up, all bolts removed, went to pull the intake up, and it was lose, I thought here we go finally...but something was stopping it. Turns out it's a PCV hard pipe at the rear that literally snakes in an around the back of the intake in a 'U' shape, over around the studs (green arrows). There's even a support bracket that attaches the PCV hard pipe to the water pipe above (orange circle)! As I'll be doing the coolant bypass, I…

Someone please help before I torch this thing Just been rebuilt, has run away fine until out of nowhere during cold idle it hunts, then drops well below 1k revs and dies If I keep a bit of throttle on and warm it up it isles rough as guts when until it's warm where it seems to be okay. Took codes, faulty temp sensor, replaced no change. Found the throttle bodies were out of sync and not closing fully. Fixed and no change Went about the set idle procedure. Idles good TPS has been adjusted Had the idle control valve off, cleaned and connector ohm tested. Have the air regulator apart and seems to be working. Plugs out cleaned and …

Interesting choice of vehicle in this news item in Portugal, was like I know what that is !! seriously news message though....dangerous out there kids ! Jeff

Ok, so I pulled the engine out due to ongoing maintenance and noticed this.... Am I right in thinking the coolant line has been blocked off? If so, for what reason?

My wheels need a tidy up and at the moment I'm thinking of going for a recreation of the original finish. As standard the have a diamond cut lip and centre with plain silver spokes. I imagine that this is going to cost quite a bit and may not last that long. There is a specialist nearby that can do this though. Other options- Plain silver Slightly darker silver Other options considered but not for me I think Matt bronze Gloss black Any thoughts/ ideas?

so my uk clocks have arrived and there seems to be one plug different to what is on the car, i have a 12 way socket on the gauges, but only a 8 way plug on the car, do i need to change the plug or can i just connect it up? i just don't want to go and plug anything in and damage something. looking at the extra pins on the socket they look to be mainly grounds that are connected elsewhere. the uk clocks came off an early car. JDM clocks Uk clocks

Just fitted the first one of these to my new zed but I was wondering what is the point of the gold bracket ? I can't see any reason for it to be there.

Ok, I have my plenum off finally! I'm going to do the coolant bypass, the green lines is where I need to install the bypass pipe. The YouTube video ( ) which shows how to do the NA coolant bypass doesn't mention the pipes I've circled red. So I guess these have to remain. Unfortunately I've cut one of them. I'm guess if I simply remove these; coolant will be pumped out everywhere? Also, one of the main reasons I've removed the plenum was to replace the knock sensor. I understood I could get at it by just removing the plenum, as long as the EGR was removed, which it is. However, I see no way of getting to the knock sensor without removing the l…

Guys The speedo on my 300zx seems to be malfunctioning and isn't displaying the correct speed e.g on my way to work this morning was showing 140! Now it is showing 180! I knew they were quick back in the day but doing 180 while stood is amazing for any car! Could it be the cluster or a sensor of some sort? Thanks in advance

ok moving on from yesterday i've just had a lucky find and bought some uk clocks, there is quite a considerable difference in mileage though, mine are on 69,000 miles and the one i have bought are up on 200,000. now i've been looking at both sets online and the connector on the odometer/trip counter both look the same, is it possible to fit my odometer from jdm kmh clocks into the uk clocks or would they register mileage wrong? if thats the case could the motor be swapped as i notice it's only screwed on the back of the odometer unit.

I'm going to attempt an injector replacement, it's no.1 injector (by oil filler). Has anyone removed and replaced this without Dremel work? It looks like by removing the throttle cable bracket, that it should be doable.

Hello!! Not been active on the forum for about 12 months (my bad) . Ive not got the car going yet after 6 years now, but I'm having another attempt (time flies!), one thing I can't seem to manage to get this intercooler to fit http://www.ebay.co.uk/itm/REV9-Front-Mount-Intercooler-FMIC-for-300zx-Z32-Fairlady-VG30dett-Twin-Turbo-/161875227564?hash=item25b083f3ac:g:VJIAAOSwAYtWNSzm I think I need to cut the pipes, I've had it fitted without the front bumper on, Ive cut into the plastic bar that goes across the front of the car where the lights sit in, still no joy. Anyone any tips? Shall I cut the ally pipes? If I can manage this I can then underseal i…

hi guys got a few instrument gauge bulbs out, from memory are the main lamps that go in the rear t5? as i have to pull the clocks i also want to replace the lower illumination lamps these are a smaller lamp i think that come with the holder, what size are these? i notice there are less than 5 available in the U.S, but it's not worth me paying carriage on just a few lamps. so looking at alternatives which i'm sure must be out there.

hi guys,new to the club hope you can help me. engines in safe mode,tried resetting everything still the same,buzzing from gearbox when i press throttle,reset tps buzzing goes away turn ignition off then on buzzing comes back.any ideas?

Hi does anyone know if the bolt on flange on propshaft just past the centre bearing will interchange between na/ and TT just wondered if the splines were a different size .I need to change bolt pattern to na on front section of propshaft to match up with a swb na rear section .This is on a TT manual slicktop with na diff and subframe beginning to think should have gone 1 piece prop now .thanks

Hi everyone, when i press the clutch pedal there is a creaking, its coming from the gearbox linkage. Does it need a little grease or is it something more serious?

Chaps Hoping you can help/advise. When I turn my side lights on without the key in the ignition, the sidelight come on fine. However, when I turn the ignition on or start the car and then turn the side lights on the n/s headlight comes on as well with the sidelights. When I put the headlights on then the o/s headlight comes on. I initially thought it may be an earth issue but don't think it can be as if it was then the issue would be there all the time regardless of having the key in the ignition. The car has an after market hid kit fitted and I have tried a normal bulb to see if this would solve the issue but the problem is still there. Any help appreciated…

Trying to track down the part number for the starter relay. So far I've got 2523089981 which I think is for the automatic and I believe the two are different. Does anyone know the part number for the manual one by any chance?

Hi Gents, My 300zx has been playing up over the last few weeks. I have tracked it down to an ECU fault, it is quite well documented on twinturbo.net Basically the car will be driving (under any conditions) and it will cut out, CEL light comes on and aux fan comes on, Can't pull any codes as the light is on solid . If I disconnect the ECU and reconnect it the issue goes away for a day or two then comes back. The car had a new loom a few years ago and all the wiring looks to be in good nick apart from wire off the ecu which is held together with one of the blue plastic crimp clips. The car was mapped by Noz a few years ago so I believe the ECU chip to…
