Gav240z

A few reasons really the first is that the substitute they put in for the lead isn't all that good. Second it's not as powerful as the old leaded fuel was and third because it's overpriced and really no better than normal leaded fuel. I have been running the car on optimax for more than a year and it definately runs better than premium fuel.:classic:

Dunno about optimax destroying gaskets maybe the cleaning agent inside it might cause it to deteriorate them dunno I've run optimax with my Z on Su carbs no problems so far. A stock 260z wouldn't require a high octane I think the manual says 88 octane and up. However if your valve seats are brass(notsure) you might wanna use a lead or lead substitute however if your Z has done high KM's then you will need to rebuild the engine within the next few years anyway and therefore it won't make a difference till then. Lead substitute is a joke in Australia. You can run normal unleaded but you'll probably loose some power. Stick with optimax or premium.

what timing did u adjust? If not electical then mechanical timing if it's feeling really sloppy could it be a timing chain that has streched and slaps around? The tensioner could have broken? Sounds like detonation to me have you done as other suggest check valve clearance electrical timing etc?? Maybe it's a broken valve is it just under load what if you rev it at idle sound ok? You can always check if the engine is on the way out by doing a compression test and checking your oil pressure for a start. You could have a problem with your distributor are you running a mechanical points type or electronic one? Pinging is difficult to describe I always say it's a clacking noise sorta like a chain slapping around or when u almost stall a car you hear a similar like noise. The fact that you mention is higher gears it being more common would mean under higher load and usually means pinging also if your travelling along and your at fairly low revs like 2500rpm - 3000rpm maybe a bit less and you give it wide open throttle do you instantly hear the noise? If so I'd put my money on an electrical adjustment and definately pinging.

Might be a silly question but what is the condition of your lower bushes? Are your drum brakes in good condition? just trying to get an idea here. :classic:

BTW i wax her often but hadn't had the chance yet hence the car cover . So i don't have to wash again before applying the wax . Do you go with the canauba wax that's meant to take really hot tempretures?

voyeurism - An obsessive observer of sordid or sensational subjects. Hmmm I can live with that . It strikes me though how i can leave the car under a cover in a garage free from car parks to find that someone within my house knocked the side mirror so hard it won't screw back into the door properly. I feel i can never win why me :disappoin . I had it reversed into once and the front of the bonnet damaged $700 and 2 weeks later someone does it again this time the bumper $300 more. I go to great lengths to look after my precious maybe I should just stop caring .

What's your location in Australia I paid $700 for 4 new struts all around in a 260z that included labour somewhere close to $600-$700 anyway. Depends on what brand they are I guess. To me it doesn't sound unreasonable.

I had GT2 on PS and I managed to get the S30 Fairlady Z it was a 240zg oh yeah I had fun I used it to win alot of the races did it up to 350HP shame no turbo L28 engine could be done just N/A Tune. A friend of mine got the KPGC10 GTR in the game also but i could never find it at the dealer ship . I just watched the GT4 game trailer and loved it I'm so inspired now I've always wanted to program PC games like this hence the reason i'm doing a multimedia stream in computer science for an additional 1.5 years after my advanced diploma in computer science this year. Looks like alot of fun. Also did you guys note that the factory from which they were taking photo's of the cars in Japan from the Nissan factory was the same as the one Alan visited a few months back? Saw alot of great cars and from the fairlady 2000(Roadster) to the 350z. Hmm i'll have a look this week for the Nissan game again have a feeling i lost the cd cause I just didn't care about it.:disappoin

your right about the one way valve part

I have it somewhere but where is the question I have to find it i'll have a look on the weekend for it. To be honest guys it's really not that good.

No idea on the 05 head. The P90 definately has a stamp saying P90 I have one in the garage . N42's on an L20? seems a bit odd are you sure they weren't placed there later?

There is as Alan would point out they change hands privately and for large sums of money.

I have a F54 block with flat tops and an early E88 head off a 72 240z i get 180 PSI across all cylinders dunno how to convert that to a compression ratio format but if anyone does let me know.:cheeky:

HSG130 would indicate a RHD 280zx most likely of japanese Australian or NZ origin.

Not in WA get in contact with member Cuong Nguyen he is based in Perth I believe and has an excellent 240z that just underwent a lot of work

Completely agree with you, I had a 260z that im sure had only the basics done to keep it running. I replaced the struts in it for the first time in 25 years of it's life they were the oil filled struts yikes. I'll keep working on him but that's if he wants a Z in the end of it all he may save the money and want something newer as you know an old Z isn't for everyone.

Thanks for that it looks a good car but i don't think he will be spending that much on a Z. I know if i buy a Z in future i'll be spending a decent amount of money. That's if I get a second Z ;-) He originally wanted a 2+2 for the extra seats so he can drive his younger brothers to skool I'm trying to convince him to get a 2 seater so you could say im half way there now getting him to spend a bit more money on it is the next stage .

Yeah i think it was something like 70 - 73 or maybe even later for the ZG model run like 71-73 i think the latter. So no 2+2 Gnose model ever was released there was a prototype at the tokyo show in 74 with the intro of the 2+2. I kinda like the car but I don't think i'll go for a 2+2 again unless it's a bit of fun for me and the boys 2+2 with an RB26 . I too was waiting for Alan to chime in and make a few corrections. Still i wouldn't mind grabbing that Gnose off it

Having bought my first 240z at 17 i realise that in alot of ways it would have been a good idea to wait until i was older to buy this kind of car. The main problem is when your young generally you have small pockets and can't fund something of this kind. $500 now could be $5000 in 3 years. Having said all of that buying a car at a young age and fixing it up with dad is a great way to hang out with dad and gain some knowledge about cars. I've learnt so much when i started I didn't know anything really I didn't want my step father to take the dizzy cap off cause he might not put it back properly. how things have changed in just 4 years. If your dedicated and you love the car by all means do it I look back now and don't really regret anything except buying the 2+2 hehe. If you like the 280z it might not be the best idea to get a $500 beater. Keep earning money doing summer jobs put it aside and by the time you can have your licence you'll have enough for a great 280z that won't be rusting out everywhere. As for women not caring what you drive yes and no if it's clean reliable and doesn't take much $$$ it's a good idea for a daily car. If you can have a project that doesn't require to be on the road all the time even better if i hate anything it's driving my 240z daily hence y it's been in the garage more time than on the road last 4 months . As for 280z values well I think the best thing to do is get it tested by a professional mechanic who will give you a good opinion and advice and take it from there. Pay more for anything that won't require alot of work.:cheeky:

Well yes you may be right but at least you won't be the one having to correct the poor install at a later date. I'm not always fond of the work other have done on my car so I've always done most it myself. I never do body work and it seems to be about the only I have ever had to complain about. I need to get my women fired up next time and do the negotiations . I'm the type who will usually put up with poor work and never return. I'm glad you stood your ground and made them correct the problem, my problem is once someone does't do it properly I just don't want them to touch it again.
