I've been trying to isolate a chronic boost leak and just can't for the love of god find out what the issue is. Currently I've got the front end of my Z off (and as a result I've now missed my MOT) checking as much of the pipework as possible, everything is tight, all the hoses are fitted correctly and in good condition yet the boost needle sits on 0. I have an additional boost leak somewhere else which I have had for a while that I can't identify either noticed by when off boost, vacuum doesn't drop totally to -14 (sits around -10) Despite rigging it up to a boost leak detector, absolutely NOTHING and it's driving me up the ****ing wall. What else can I possib…

Just incase I need them , does anyone have for sale , a later type ASCD control unit and or the cruise control unit which sits in the engine bay, Let me know Pls cheers Sayers 07929 159828

Tried the search function but to no avail, I can activate the cruise function using the right hand pod and the light on the dash comes on, however when I go to engage the cruise control the second lights flashes , and the cruise control does not activate, Anyone got any experience or know of any diagnostics etc Cheers Sayers

Am I correct in that I saw a post here recently where someone said the high pressure hose can be rebuilt if i take the old one to a hose specialist engineer type place? If so, what specification hose would i require? If not, hey ho....I'll just buy a new one instead Secondly, I've started the Zed up for the first time since Nov/Dec, and heard a loud (ish) tapping from the drivers side of the head/block area until the oil warmed up on idle as i recharged the battery...should I be worried, or is there something else I should be checking during the annual fluids and filters change? Thanks.

I have non turbo decat pipes pictured below, they are advertised by Japspeed as turbo or non turbo, so my question is, when i convert my zed to a TT will these match up to the standard turbo as they are or will i need something else? Coming from a UK TT and will remove the precat too Cheers

As stated in the title - has anybody got one for sale, good working condition..

Guys need urgent help. How do I ground the fuel pump ecu so it runs flat out all the time rather than phased

Hi guys, anyone fitted one of these; It just seems everything is at the wrong angle to undo and I'm starting to think i need to remove the steering collum to do it. Engines out so I thought it would be a quick simple job, sadly not.

My paddle clutch decided to break up on me last night, so I'm in need of a good replacement clutch. Does anyone know any UK based companies that sell a good uprated clutch, probably good for 450bhp. I was going to get the RPS street clutch, but I'm concerned how long delivery from the states will be. Thanks!

Does anyone know if the pistons in the standard Sumitomo calipers are the same size between both front and rear calipers please?

Been to powerzed today and great to hear the 300 has got a clean bill of health, and would like to thank Jim for his time. Top bloke.

Hi guys just a quick one is a swb and lwb the same petrol flap thanks .

I know this thread is not about the 300 z but it is about the 240z. And as i have said before. If i was ever to get rid of my 300z it would only be for a 240z. My question is in todays value what would one exspect to pay for a nice clean example oh and right hand drive. Cheers.

I plan to run an MBC to control boost and in my quest for a simple clutter free life, I'm thinking I can just bin them. I no longer have a dett sensor so is there any good reason to retain them?

In your own opions what would you say is the best show/ meet of the year. The one not to miss.

I'm fitting my rear diffuser soon and am planning to remove the stonechip effect on the bumper, I would also like to smooth the coach line groove at the same time, don't want to replace bumper or fit a skin over the top. Just curious if anyone has attempted this and if so what were the results.

Since bringing the Zed out of winter hibernation the temp gauge has been playing up. From cold it has a strange issue where as soon you accelerate the gauge goes down, almost exactly does the opposite of the turbo gauge vacuum, soon as that starts giving positive boost the temp gauge goes down then returns back up as soon as you take your foot off the gas. Once warm no issues. What's should I check?

Still mucking on with my boost controller, anyway, I've decided the wiring may not be working since one wire was sticking out a little lol. So, I've took the pins out of the connector to re-wire them and they look a bit pants (cos of me trying to get them out). Anyone know where I might find some the same size? Maplins didn't have any...

For quite a while now, I have been thinking about changing my interior. When I bought the car back in '05, it had tweed, albeit in very good condition. However, I didn't like the feel or appearance of it and about 6 years ago had it all gutted and drummed with a 2-tone leather. I like the smell and look of leather, but it's not supportive and it creaks. I've been speaking to Mondo on and off about having it trimmed in an alcantara / leather hybrid which is ultimately what I will have done toward the end of the year providing that I am still living in the UK as there's a good possibility that I won't be. In the interim (intentional word), I've bought a very tidy …

Just wondered what the rubber blocks are for in the subframe had to remove these before blasting and powder coating there held in by 3 13mm nuts . Some say to do with vibration or damping . I read only fitted on manual car subframes . Just curious anyone know what theses do and do I need to refit them thanks .

Hi guys I've removed all the bushes from the alloy rear knuckes I've also split the hub part off the knuckle . Are these alloy knuckles factory painted black or are they bare alloy . I've tried cleaning them with wire brush and gunk but not come up that good . Just wondered if anyone had cleaned these up and what did they use thanks .
