The rich are getting richer.....
The UK seems to be suffering the inevitable effect on the cost of living of having 1/4 of the population of the USA living in an area the size of Texas. And in London multiply that by a factor of probably 3 again. From a comparison of UK vs USA perhaps the middle earner income figure isn't so different, but that the cost of living in the USA APPEARS ( in my fairly uninformed opinion) to be less. I am basing this on 1) price of fuel in the USA is about 1/3 what it is UK 2) Things I buy for my Z from the US are regularly cheaper to buy from the US even after factoring in shipping to the UK, VAT(taxes), duty and whatever else I get charged for. Hardly a thorough cost of living comparison I know but thats my experience AndrewB

Income poll...
Seems we get paid about the same as you guys over here in the UK but our fuel is US$5.70 a gallon.!!!! I'm spending on 2 z's at the moment. Somehow I feel better having those bits than the money in the bank, so I must be truly Z obsessed. :classic:

Mike Coming to this a bit late like, but when was the last time you visited the UK? I don't know anyone who doesn't have a dishwasher. !!!!!!!!!! Can't vouch for the rest of Europe though.

240z overbore
Hi guys/gals I'm trying to ascertain how to go about overboring my 240z engine to take 280z piston, like rebello do. I'd be interested in any experiences re compression ratios (e31 head) and whether I need to change the conrods (I have the early thinner bolt ones) and any piston height problems etc Thanks for any help.

Early bumper guard rubber
My 240z is April 1970 and the overriders have 3 bolts and one rubber nipple holding the rubber to the guard. I don't however know whether the rubbers are the original.

original jute material
26-thz do you know what year z those ebay pictures came from? I might be wrong but I thought the earlier cars' rear shelf jute was different as the plastic stowage compartments were in the way.

original jute material
Kats that's a great looking interior you have there!!! I agree with the cut for the section that goes under the seat. Can't comment on the front footwells or the rear deck unfortuately. You may already know this but there was a jute section behind the rear seat that goes part way up onto the stowage shelf. Mine from my 4/70 are pretty ragged but I might be able to ascertain the original cut if you can't get it from anywhere else. Is that jack holding clip the original? Mine is different ( made mostly of rubber) whereas yours seems to be all metal.

parked neatly
rust proofing? ( I covered the floorpans of miine in grease when it was in storage) or could you have a gearbox/diff leak? Gear oil is pretty thick once it get mixed with dirt under the car

5 cylinder 240z
My sentiments exactly!!!! As the engine has done at least 120,000 miles it doesn't make any sense to just try and replace the one piston/bore. I'm currently trying to find out what I need/how to go about it. I know that rebello do an overbore job on 2.4 engines that uses 280z pistons but I've not been able to find out anything yet. I will probably post a thread here for some help.

shotblasted suspension parts
datsunzguy thanks for your comments!!! these were done professionally but I know they used coarse metal grit not beads, as there was a lot of pitted corrosion that beads do not remove as well. The struts came out really nice. I was reaaly surprised as they were so rusty beforehand. You could read the original nissan part stamp after blasting regards Abas

Engine Expert for Head Info
I'm no expert, and I can't remember where I heard this but as the bottom line of the 'E' on the head marking on the spark plug side of the head is very close to the head gasket flange, it is possible that if the head has been shaved that this lower line will have been lost. So if the head marking on your E31 says 'F31' then it is almost definitely been shaved by a considerable amount. If it has only been shaved a small amount and the head still says E31 then this will not of course work.!!!! Hope it helps

dropped valve damage to E31 head
beandip Thanks for your comments. there is no sign of overrevving damage to the other valves or pistons so I think it was due to a weak valve spring or possibly a poor repair job somehow ( the engine had a new head gasket on it when I pulled the head) E31 heads are rare over here. I'm glad the damage appears 'fixable'.

more gas tank questions....
Does anyone have any idea how to remove dents in a fuel tank? The previous owner of my 1970 z decided that the middle of the fuel tank was a good jacking point for the rear of the car:stupid: A friend of a friend thought I could 'blow' the dent out with compressed air, but I'm doubtful I could get enough pressure to do so without something breaking first. thanks for any help

Good paint results with a rattle can?
landmizzle I painted the engine bay on mine with rattle cans ( see my gallery). Looks OK from a distance but close up its nohing like as good as a professional spray job. It will however do for an engine bay where a large number of other components obscure any imperfections. I wouldn't attempt any exterior painting with a rattle can.

5 cylinder 240z
So a 240z has 6 cylinders no! 5..... piston smashed as a result of dropped valve. Wrist(gudgeon) pin has done a lovely job of scraping a large groove in the bore :-(

Hatches_1
I'm toying with doing the same on my early 240z as the previous owner 'kindly' cut speaker holes in the rear deck for me!!! I hope I make as good a job as on yours.

Greasing drive- & half- shafts
So you can remove the UJ's on 240z driveshafts without a press? How would you go about doing that? Is it something that can be done by your average DIY'er?

2 brackets...what are they for?
240znz just also to say that your car doesn't look as if the whole rear deck has been changed, just holes have been cut in the rear deck to accomodate the metal tool hatches. OK it might not be original but the tool boxes in the rear deck are a lot more convenient/usable than the plastic originals. ( as the plastic toolboxes no longer take up space behind the seats you can also treat your 240z as an occasional 2+2 if you have some short passengers!!!! although I accept this might not be strictly legal.

2 brackets...what are they for?
240znz, sorry to say,I agree with Nick that the hatches have been retro fitted. My 1972 z with hatches has a recessed flange in the deck all the way round the hole. You also have the remnants of the 'swiss cheese holes' in the rear deck that you can best see on the pictures that 26thzposted on this thread earlier. Finally there are the 2 luggage strap bolt holes holes that are right at the top of the picture (ie so that luggage strap goes the entire length of the rear deck as on the earlier cars), whereas the later cat had the luggages trap bolt holes roughly in line witj the rear suspension towers.

Finally My 240z Video.
Divx seems to dislike my PC intensely in both windows 98 and XP. I did see the video once ( ace!) but I can only get the sound now. Nice to hear a z again, its been too long. You need these kind of things every now and then to keep you motivated (especially with a rebuild that is 12 years and counting!!!!)

240z engine rebuild options
Alan Good to hear there is someone less than 3000 miles away!!! I'm near Bournemouth on the South Coast. I'm definitely interested in following this up. Do you have an E31 head for sale? Was going to get mine repaired but not sure now. I would lilke to keep my original engine if possible, do you know what the max overbore/piston size is for a 240z engine? I'm thinking of increasing the cc by overboring (which it needs anyway) but by keeping the crank the same. You have some great pictures in your gallery!!!! cheers Andrew
