hi im after a veilside rear bumper any one know where to get one? 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

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?

Anyone on here at Sunbury Cross roundabout at about 11pm last night? Saw you from my flat window (and was worried it might have been my car!!!). David

I was originally going to order the kit off ebay, but after reading the post yesterday i have been put off. So i'm going to have ago myself. If anyone has got any instructions or tips i would be very greatfull. But i do have a concern on the door cards how do you get it to wrap around the end of the door as its a right angle, all kit manufactures use stitching but i'm affraid i can't do that so what is my alternative. Also is there any other tricky party surely in places the material would pucker up how do you get around this. Thanks

I want to give my plugs a clean and i'm not sure the best method. My car has been missing all over the place and I had to replace a 4 week old set of platinum plugs because unburnt fuel had coated them in carbon and crap. (It's a long story) Anyway, I was thinking maybe just petrol and a hard scrub with a tooth brush or contact cleaner and a scrub...? Any suggestions?

Have any of you guys had to have welding done due to exessive corrosion i.e. inner wings, sills etc :confused:

yeh guys, at the moment I'm in search of a low millege z. of coarse, most of the LM Z's i see are imports. looked at a few but was told they have the service history but its in Japanese. is this to be expected from all import sellers or will a repitable dealer say different?
