Fitted these last night with some help from Leigh again (cheers mate). Problem is I bought them second hand, so didn't get the hoses. I've used the stock hoses and they line up OK (Bracket lines up with tow eye bracket and the 2 holes on the fron line up with the ali plate) so I'm assuming they're in about the right position. I basically have 2 problems now. First, the coolant resevoir is forced out of place by the back of the cooler and will hit the wheel. 2nd, the bottom of the front arch liners hits the bottom of the coolers, so it dosen't sit right. Is this just me, or is it a common thing?! I've junked the carbon cannister anyway to free up the air flow a…

I took my car to a garage in Bristol today and he diagnosed my car today as having a problem with my car running way too lean. He reckons that after doing an emissions test / lambda senser O2 Sensers etc etc that my car is not getting enough air - fuel ratio mixture. He then went on to tell me that I need to buy an AIR FLOW METER COMPENSATER MADE BY APEXI (Approx £70-£80), allegedlly they are a small box that connects up to the ecu/aft and you can manually adjust the air flow to calibrate to the fuel mixture. CAN ANYONE VARIFY THIS OR STEER ME IN THE RIGHT DIRECTION ? AS HE RECKONS THAT MY CAR IS RUNNING THAT LEAN HE IS SUPRISED THE CAR IS RUNNING AT ALL. Duffer, John…

Does anyone know of a place in hertfordshire that can do my cambelt cheep ,but are good, Hertford area :x:

I have wee problem, my zed starts first time, with no probs whatsoever. even after a min or two it's fine to switch off & start, fires up sweetly. But if I run it for say 15mins+ switch off & start up again it turns over & won't fire unless I leave it for for a wee while & start it up again. PTU? new plugs? I thought it may have been an earthing problem as for some reason when it happen previous I clamped a jump lead on the - terminal and on the block it seemed to help, so I bought the kit off Pete Sh. Still happens tho :-/ so it wasn't that (nice kit tho Pete ;) )

ANyone got an Ultra Turbo Timer? There a Japanese company apparently and I've been given one for free (off an RX-7)... wondered if anyone had one fitted?

I wanted to buy one from the zcentre but it seems they are all on holiday till the 4th may, which is a prob because my car is booked for a respray on the 10th, if purchaces are done over the net does this go through him or straight to his supplier :confused: thanks

Noticed the needle creeping up again when stuck in a queue. I've noticed recently that my heating has been working intermittently. When I press the Auto button I sometimes get a 'ping' noise from the driver's footwell. Sounds like the spring that opens the heater core valve doesn't always work. Checked under my mat and my footwell is all wet. I changed the matrix myself back in november but have a feeling that this one is on the way out too. Would a 'sticking' valve cause it to leak or could it be the matrix has broken again. Any ideas what would cause this after 6 months? I will get it replaced under warranty from Nissan but fear something could be causing them to pop!!!…

The 2nd and 4th gear slightly crunch every now and then, does this sound like a gear box or a clutch?

can you get a clear coloured wax? i use zymol and even tho th stuff works really good (and smells really nice) its a sky blue colour and when it dries it goes white. i always end up with wax inside and around joints like the door handles and mirrors, iwas hoping itd all wash out in th rain but its still ther and buggin me. but i still cant be botherd to go n scrape it all out with a pin, jus too lazy

Just wondering if you can help me out. When i was first getting my Z last year im sure i read somwere that the manual car comes with bigger turbo's. If it's true could you please tell me as i said this to somone the other day and they replyed "WHY??". What a dong i felt when i couldn't explain :o :nelson:

Is there anyone near Leeds who can give me a hand with the following: Plenum removal / refit 555 Injector installation Mounting / checking T28 turbos General water bypass stuff EGR system removal I can manage most of this myself and have all the parts ready but I really want to make sure it's all done right before I put the engine back in and having someone on hand who's done it before would give me a lot more confidence. :confused: Tea/beer etc supplied FOC :duffer: Possible free spares from a wide selection of upgrades! :hyper: Cash if needed! :mac1: Got to get this beast finished for Billing! Chris.

Folks, When I travel at over 85mph I get vibrations from the front. They affect the steering wheel and make things in my rear view mirror go fuzzy. Clearly this is not a problem on normal public roads, but I could do without this on the track. I've recently had the prop shaft centre bearing replaced, which fixed the thrumming at 40 and 60mph through the seats, so I don't think it's that. I had the wheels balanced about 10 months ago, but I drive over 10 million speed humps a day. Do you think it's likely to be wheel balancing, even if the vibes only become noticeable at very high speeds? Any other thoughts? Cheers, Russ.

Flashed and went by me in the opposite directly along the RING ROAD towards Fosse Park/ Meridian Business Park last night. ;) Bruiser

I have a strange gurgling noise at idle sound like it is just in front of the passenger door.. pick up the revs by a tiny (and i mean tiny) amount and it goes :confused: have been told it could be a breather filter filled up with water?? anybody had this b4 and if so how do i cure it ? its driving me barmy!!! cheers

As the US guys are very loquacious, I make a try with you ..... :D Here is the follow-up of this long story : Part 1 : http://www.twinturbo.net/net/viewmsg.aspx?forum=technical&msg_id=871799 Part 2 : http://www.twinturbo.net/net/viewmsg.aspx?forum=technical&msg_id=878788 I performed a compression test several times with ENGINE COLD, the results : (I added half a coffee spun of oil for 2nd and 3th attempts) #1 : 160psi > 175 #2 : 175psi > no other try (to keep it dry) #3 : 160psi > no other try (to keep it dry) #4 : 140psi > 155 > 170 #5 : 135psi > 145 > 155 #6 : 160psi > 175 I cannot perform it…

What's this ? And is it worth having ?

Needing a bit of advice, sometimes when i start the car the light will come on and off for a while then just stay off. But this does not happen the whole time. Any ideas?
