What's involved in smoothing a plenum? Is it really simply a case of sanding it til the surface is flat...?

Hey everyone! I have had some pretty crappy news today, work is having to do a relocation due to issues with our office and it is going from a very short cycle ride away, to a 2 hour daily commute :( I have been trying to work out how to tackle it most ecomonically and just can't make the monthly finances work running the zed for it. I think it is going to have to be the purchase of a deisel run around at the expense of my baby Z... :( I have already invested a lot in her since picking it up last month and was expecting to be keeping it for good but this has really snuck up and thrown all my plans out the window. If I can work any other way out t…

I was going to put this in the other fuel tank post but thought it was best to start a new post so everyone would see: If you spend £50 at BP you get a token for Pizza Express 3 tokens (£150) = free dough balls and a pizza! Worth about £15. Ive had 2 already from filling lorries up, i did put £800 in afterall. They dont give you them for Keyfuels or other fuel cards though unless you ask nicely (for the other lorry drivers on here). Pretty good if you use your zed a lot. Or any other car for that matter.

After thinking I had a plug go down I changed all six tonight only to find my misfire is still there. I swapped two coil packs to rule that out and I checked there was actually a spark, and there is. What next? Compression test? Rather than a mechanical failure I'm hoping its a failed injector, is there anything else I can check? Would the ecu show any codes for a bad injector? Thanks

i was talking to a guy who had a 300zx thats modded a far bit he had removed the rad over flow bottle and just had the pipe running to the ground . the rad is ment to send the water from the rad to the bottle if it gets to hot and suck it back if needed but the rad cap is a one way valve when the water is hot it can push water into the bottle cus the water can push the valve upon and push water thro it but its one way so the water never get sucked back so he removed it to let the intercooler flow better does this sound rite ? as its not a header tank is it llike in a normal car

although it still drives the tubbies have gone. the detting i had has turned out to be turbo stalling out and has what seems to be a massive lack of power under boost. so now its a big decision time, 1 repair 2 sell as is 3 break it its gonna be a while before i could repair as ive had to have alot of time of this year due to bad health.

Hey everyone, Need some input with my issue. Here it comes.... My idling recently got lumpy. I suspected this to be a breathing issue and gave my twin HKS induction, new filters/elements. This didn't solve the lumpy idling, so I then suspected the problem being due to the MAF. I took the MAF off and gave it a clean and connected it all back up. This led to the air flow being all over the place. The gear changes weren't right and upon putting the foot down, the Z seemed to rev up high and engine got loud and power not up to standards. Just didn't boost correctly. I then got hold of a perfectly working MAF and an Apexi induction. This completely cured the id…

i will be upgrading my intercooler in the future and am thinking about fitting a intercooler water methanol spray kit has any one tryed this. the sti has this fitted and i had a mate who had a evo and had it fitted . it dont cost much to buy a kit so mite be worth a go. what do you guys think.

How much does it cost these days to fill the zed up? Getting mine back on sunday (cant wait), just wanted a heads up before I fill up. How many litres does it hold? Last time i put any in i think i was getting about 60miles to £20 (long time ago).

Hi guys. Need a bit of help. I'm running the car in. It's about 200 miles in now on brand new turbos and everything. Went to the Brands Hatch show last night and come back. Today when my friend was in the car he noticed my left hand exhaust from the rear of the car is puffing out white smoke. It only happens with the throttle pushed briefly and then coming off of it. Literally for about a second. The smoke takes anther second to come out then lasts for about 5 then stops again until you blip the throttle again. Any ideas? PCV valves? The engine is fine and gearbox. No funny noises. (:

A couple of times when i've left my cover off the Zed i've then opened the boot to have water come out from the inside plastic surround. Has anyone else experienced this and if so where is the ingress happening, im presuming the window seal but it looks fine and the spoiler looks like it's sealed as well. I've searched the net but only found one thread relating to this that was vague.

having trouble finding this relay i understand its in the footwell but i can figure out which it is

It's been three years since they were changed and I have a faulty plug, which ones do I need and where's the best place to get them? It's a 92 uk twin turbo Thanks, Dan

Can you tell me what the pipe assy from the gearbox (auto) , one either side with banjo connectors going forwards, up and under to the bottom of the rad is called. Thx Rich

as above ive seen some zx's with some panels under the bonnet that seem to fit around the back of the engine bay? anyone know what there called so i can start searching for some??

As per the title. Can anybody tell me what box is for? I'm guessing lighting. I had two wires corroded and broke off when I touched them, would be nice to know what I fixed.

Only caught a glimpse in my rear view mirror. Looking good with its targas off heading towards oldham at about 4.30

Was at this hill climb on Saturday to cheer on a Zclub member MikeB in his 1973 240Z. It was a great day for racing and the spectators as we were all treated to a feast of awesome machinery in full flight.A good day for Mike also as he won in his class:bow: Here is his fantastic 240Z Short video of Mike at the start point( click on picture.) And going across the crossroads after going through a chicane

Hi all, I currently have my engine in a hoist and it's partially removed, a little above the mounts. The gearbox is loose and currently supported by jacks. The gearbox and engine are almost separated (I think), there is about a two inch gap between the back of the engine and the gearbox, I can see the flywheel and some of the clutch cover. However, I've tried lowering the engine, and the gearbox, to different angles etc, but I just can't free it totally! It's like something is stopping the transmission / input shaft coming out of the flywheel / engine. Any ideas, or tips, or anything, I've been on about 2 hours now, and getting nowhere fast? C…

I thought the problem was the switch as if you waggled it a lot it would sometimes work, but unfortunately fittting a replacement did not fix the problem When you push the switch to 'close' you can hear what sounds like a relay click in the door - obviously the window is fully closed already When you push to open you don't hear anyything at all Is there a known common problem that causes for this? I ask as the drivers window on my old Z was temperamental too Rich

What is the technology behind these? I already have one but want to match up quarter panel window sun blinds in the same colour... Many thanks, Dan

I know I want 18". Most probably will be rota GTR's. My car is is lowered 30mm, what is the absolute widest the rears can be without catching, I don't mind having a bit of stretch on the tyres either. Also, as for the fronts, what is a sensible width? 8j? What offset should the front have? Thanks, Dan

this isnt far from me and i posted it on facey and found a friend of mine and many other (peter from pps) knows the owner and says its as clean as it looks, also been stripped inside and deep cleaned? anyhoos, just thought i would post it as it looked clean and may be of interest to someone, could also be due a price drop, it has had paint on it before but is a very good job apperently http://www.ebay.co.uk/itm/1994-NISSAN-300ZX-CONVERTIBLE-PEARL-WHITE-VERY-RARE-FUTURE-CLASSIC-/171091918518?pt=Automobiles_UK&hash=item27d5df7eb6
