  1. Yeh probably right about the cold start. I think of it this way. Imagine what other cars the owner must be having not to drive the Z! If you go through that thread u will see that there is a forum member with a Z tune with almost the same milleage!
  2. Came across this today! Car has only 39km and never driven since delivery. http://www.gtr.co.uk/forum/upload/94523-nismo-z-tune.html Isn't 2300rpm is bit too much for idle? but who cares...

  10. Brief minute contacts are oil films on the liners which does not have direct contact with the oil in the sump. These oil get burned in the chamber and goes out with the exhaust gas. Compression gets less when piston rings are worn, oil gets into the chamber when oil rings are worn. And about "Tolerence get wider". Thats why u have rings which are spring loaded. never heard of new cars needing regular topping up. Give some examples please.
  11. Where did I mention about me buying new cars every 100,000kms? I think u r not only competent enough about engines but also understanding simple english too. And could u please tell us about this "many many" cars that went wrong? I'm yet to hear of "well looked after" new toyota engines going bust. I know quite a number of people using new toyotas in sri lanka but never heard any of them going bust.. Maybe its how these "many" cars are maintained. For your info, engine oil is not the only reason a new engine can go bust. There can be so many other factors. Running low octane petrol in an engine mapped for higher octane alone can damage an engine significantly. European vehicles are mapped to 95 octane or higher and japanese performance vehicles are mapped to 100 octane. Since u r aware of the conditon of petrol in sri lankan best is to get the ecu remap to somewherer around 90. Dust, high humidity can be a problem for engine electricals too. Give them some thought.
  12. Machan what u said is correct. thats the reason u got piston rings. when u make the rings from a lower grade material than the liners u get the rings to wear out faster. thats the reason u have to put new piston rings every now and again. Pistons don't touch the liners but the rings do. oil rings actually scrape the oil from the liners thats y i said only oil left on the liner surface are the ones trapped in between hoaning lines. When i said negligible amounts i mean something like 1cc (cubic centimeter) of oil every hour or even less. And these oil will burn away rather than mixing with oil again.
  13. Ok i will try to be considerate if u try not to be obnoxious. The reason I'm confident about synthetic oil is because I've learned enough about the molecular bonding of synthetic and ordinary mineral oil to know how they break. And for ur information most of the earlier synthetic oils were either semi-synthetic or a mixture of two different synthetic oils with different viscosities mixed to get the required viscosity. When these oils break, they break into two different viscosities. one thick layer of oil which is known as 'formation of sludging' and a very thin layer of oil. Both equally useless for the engine. This problem was found few years back by the oil manufacturers and they have brought solutions to it. (They actually did proper research ) Ur knowledge of piston engines is quite astonishing:D Makes me wonder who does these research for u For ur information each piston has 2 rings one is the piston ring and the other is the oil ring. Oil ring make sure that the chamber is free of oil at the time of ignition! Oil that is in the chamber are the ones that is trapped in between the hoaning marks of the cylinder liner. These are negligible amounts. Unless the rings are worn out there can't be any significant mixing of petrol and oil. Furthermore Low octane level won't affect the oil. And I would like to know what impurities are there in Sri Lankan petrol? I know the conditions in Sri Lanka is different. Thats y asked if anyone has a car with computer controlled service reminder built in, because it takes all that u mentioned into consideration.
  14. what proof have u got to tell us that fully synthetic oil breaks after 8 months? our company cars (mostly VWs and Audis) do about 18,000 - 20,000miles before an oil change. that is not within an year. sometimes even 2 years!! VW told us that there is absolutely no need to change oil until the "Service" light comes on. some of these cars do about 200,000 with only 10 - 12 oil changes. so u telling us that u've done more research than the VW guys? There is no way in this world fully synthetic oil can break down in 8months if its NOT used!! The whole thing about synthetic oil is that it breaks down when it is used unlike mineral oil which tends to contaminate quite easily. The older your engine gets you can go onto semi syn and then mineral oils This is just ridiculus! I don't know who does these research! so u r telling me after 10 years time i should put mineral oil to my car because its old, even though the manufacturer recomends synthetic oil? Before u bring the whole "Sri Lankan conditions" thing here I would like to ask if anyone here from SL uses a car with computer controlled service reminder built in? Please let us know what intervals do u get and what kind of driving do u do?
  15. The next Toyota Celica is to be built by Subaru, the Monday morning rumour mill has reported. It has been reported that the replacement for the Celica will arrive next year in Japan and is a joint effort between the two car makers. It is expected to come in two variants – a high-performance four-wheel drive GT-Four and a more sedate GT model. Toyota is hoping to put the GT on the market in the US for just over £10,000. It will feature a front- mounted, naturally aspirated 2.0 litre Subaru engine and rear-wheel drive. The pricier GT-Four is understood to be getting the same 300bhp turbo four seen in the Japanese-spec Impreza STI. Both cars could come in a coupe and three-dour hatch bodystyles. http://www.pistonheads.com/gassing/topic.a...23&t=493094 Toyota reliability with a subrau STI engine. Not a bad idea. Found this under comments.. Hillarious "Mmmmm pretty sure that they've discontinued "Celica" as a model (like mr2, corolla).. so that WOULD be interesting to see a subaru built toyota.. or is that a toyota built subaru.. or a tubaru.. or .. god, i'm confused."
  16. It is highly unlikely that u will need to change engine oil at 1500kms. Remember that ur engine is built from high precision machinery and all the parts are more or less ready to use as soon as they come out of the manufacturing plant and If there are any impurities left, the oil filter should prevent them from circulating around the engine. But during ur initial 1000 to 1500miles try to keep the revs below 4000 and avoid full throttle in any gear. Also avoid quick starts and hard braking. These are of course not MUST DO's, but they will help the engine to settle in initially. If the main dealer recomends 5000Kms for an oil change then stick with it because even in extreme conditions It will need atleast 10,000miles for synthetic oil to start breaking up. So in Sri Lankan conditions 5000Kms for an oil change sounds very reasonable. Try to change oil atleast once a year even if u don't do 5000kms. Hope this helps

    Changing Timing Belt

    Thanks for the info. Yeh I've heard about the timing chain issues with QG16 and QG15's as well. After Renault took over nissan, most of the models came out of that factory were not up to the Nissan's standards! I was told by a mechanic who used to work for Nissan that some electronics for newer nissans come straigh from the Renualt, even has the Renault sticker on them; and also he said he would not recomend newer Nissans. But pre 2000 ones are considered 'bullet proof' because of very good build quality and reliability. I think u missed my 2nd question. Does GA14DE and GA16DE got timing chain? Cheers

    Changing Timing Belt

    I have heard quite a number of recalls from both nissan and Vaxuall regarding timing chain issues. Could u please give us some tips on maintaining the timing chain? Does the chain gets its lubrication from the engine oil? Also is there any investigation that we could carry out ourselves to find a faulty chain or tensioner? Im sure quite a number of members here must be having cars with Nissan SR20DE s. Were Nissan GA14DE and GA16DE engines came with timing chain as well? Cheers.
  19. Yes I know the topic is about sri lankans conservative attitude towards cars, what I'm trying here is to establish a comparison between a UK car buyer and a sri lankan car buyer and see what exactly affects them when choosing cars. There are quite a lot of factors such as running costs, taxes and things like that. After considering these; an ordinary citizen does not have much options but going for a car with 'reliability' & 'cheap running costs'. Which is why sri lankans go for toyota corolla rather than getting a bit old BMW or an Audi for the same price. Unless u got big bucks u don't have much options when choosing a car innit? Its the same in the UK as well as in SL. What I think is sri lankans are not conservative as such, its just they don't have a choice! Just like here in the UK most of us have to drive stupid ford fiestas even though we want something more exciting. we don't have a choice! Hope u understand what I'm saying here About the evo and 911 thingy I totally agree with u when u said people don't know much about the 911 where as Evo's performance is proven on track. But putting that as 'conservative' is questionable.. And don't worry mate I'm cool
  20. Like I said earlier I don't care!! Did i say I was the only Asian in my class? I said I was the only colored person. I don't consider Chinese and Malaysians as 'Colored' because they aren't!!! Anyway Its not important for this this topic. So we should leave it here and get back to the topic.
  21. You’re going to like the new Nissan R35 GTR. A lot. But you’re also going to have to wait for it, like it or not. The official line from Nissan GB is that it won’t go on sale in the UK until, yawn, March 2009 – and when it does it’ll cost ‘between £55,000-60,000.’ Unofficially, it went on sale in Japan on December 5 for 7.7 million Yen (just over £31,000, ouch!). And although the first 2500 out of the annual 10,000 production run have already been sold, there’s another reason why you won’t be seeing GTRs in the UK for a while yet. Nissan GB is threatening to punish anyone Tesco-Levi Jeans style who imports and tries to sell an R35 GTR in this country for anything less than the intended list price. Grey importers, in other words, won’t be getting their hands on cars anytime soon, not to sell on at a profit at any rate. Which is a pity because, having just driven the car in Japan on both road and track, I can tell you it’s a heck of a machine. Not just quick with a capital F (you expect that from a car with 477bhp and four-wheel-drive, even if it does weigh a lardy-sounding 1740kg) but also mind-spankingly composed. Way more so than a Porsche 911 turbo if you really start to lean on it, which is maybe not surprising considering Nissan benchmarked the Turbo during every inch of the GTR’s five year development program. The technical highlights of the new GTR come at you so thick and fast it’s hard to know quite where to begin. If the engine spec sounds impressive – it’s a bespoke 3.8-litre V6 which, says NISMO, bears only a passing relation to the 3.8-litre V6 of the Infiniti G35 and 350Z but which does have twin IHI turbos and develops 477bhp and 433lb ft – then the chassis is very much the centre piece of the car technically. As with previous GTRs it’s four wheel drive and centrally controlled by a very clever brace of computers, but this time it’s massively more complex and allows you to do things on the road which no other car will allow. The reasons why are various, and not especially simple to understand. For starters there’s just one rear-mounted transaxle into which every key component of the drivetrain is contained. No one’s ever done that before but, says Nissan, this adds strength and saves weight compared with a conventional four wheel-drive-system (although that still doesn’t explain why the GTR weighs as much as it does). Chief engineer of the entire GTR project, Mizuno-san, reckons he could just about get the weight down to below 1600kg if pushed – by reducing the huge 380mm brakes front and rear, swapping to lighter conventional tyres in place of the standard run flats and binning many of the interior luxuries (heated electric seats, cruise control, BOSE stereo etc). But in doing so he’d need to sacrifice too much of the GTRs inherent strength and durability. So when the V-Spec version appears in Japan in ‘about one year’s time’ expect it to be half way between the two extremes. Around 1650kg in weight and even more focused than the standard GTR we drive here. Not that the standard GTR is what you’d call blunt. Genuinely it feels sharper than a 911 Turbo on the road, which is saying something. More accelerative (the official zero to 60mph is 3.5sec, the top speed 194mph), better steering, less roly-poly during high speed direction changes, and more sorted generally, especially on a track. Nissan claims its testers have recorded a 7min 37sec lap of the Nurburgring but, apparently, certain sections of the lap were wet when the time was set. They also have data for a 7min 38sec lap on which the driver was blocked by a slower car for several corners. Both laps were recorded using original equipment Bridgestone RE070A tyres, in other words with the car containing no secret tweaks or tricks. In reality they reckon it’ll do a low seven-thirty – maybe a 31 or 32 – whereas a 911 Turbo wearing far more trick rubber with Walter the wheelman at the controls, could ‘only’ manage 7min 40sec. Truth is the GTR is a good 10sec quicker round the ‘Ring, maybe a little bit more. And on the road it feels even quicker than that. Lag from the twin-turbo 3.8 is almost non-existent above 2500rpm, and by 3000rpm it fires the GTR towards the horizon with such conviction you wonder whether the tarmac can take it. Partly it’s the traction but mostly it’s the pure and efficient flow of power to the road that makes the GTR feel so rapid. And that’s before you so much as mention what it can do through corners, which is when the gap between it and the 911 Turbo really opens up. There are no less than three driver aid systems, each of which can be tailored to suit an individual’s preferences. One controls the dampers, another the TC system, and another both the traction and stability systems. You can set them each to Race, Normal, or switch ‘em off completely, depending what road surface you’re driving on. And how brave you’re feeling at the time. With everything set in Race the GTR can be driven very aggressively on the throttle, especially on the way out of corners, mainly because it’s been designed to dial out understeer in this mode. So when you feel the nose running wide in, say, a third gear corner, rather than backing off to shed speed, you plant the throttle harder and, instantly, more torque flows to the rear axle and, presto, the understeer goes away. Then as if by magic the nose tightens its line and you scream out of the corner with a whiff of opposite lock applied. And a round of applause from any one who happens to be watching. Switch the TC off altogether and the tail will come right round if you give it the full beans, but at the same time there’s still enough torque at the front axle to pull you out of the corner. Result? M3 style sideways amusement but with monster traction (read huge ground speed) thrown in as a bonus. And then there’s the interior, which is a surprisingly decent place in which to spend time, the proper sized boot, the never-ending standard equipment list, the looks. And the image. The only downside is that the ride is stiff to the point of irritation over rough surfaces, even with the dampers set to Comfort. That could be a real issue in the UK, what with our beautifully surfaced, not even remotely pockmarked roads. But Nissan GB has time to sort that locally. And in any case, you’d be inclined visit the dentist more often if the rest of the car is as sensational as it is. Tech note; the twin turbos are no longer ceramic so the R35 GTR can no longer be tuned with relative ease to deliver massively more horsepower than standard. In fact, Nissan has written an anti-modification program into the ECU software to prevent the GTR from being tuned. They are even talking about de-validating the warranty on cars they know have been tampered with, although for sure someone, somewhere will find a way to tune their car. What’s not known, however, is how much more the new bottom end can take. The rumour is circa 600bhp, possibly less. http://www.pistonheads.com/roadtests/doc.a...=47&i=17295 Please note: Dear Moderators, could u please make Gtr into GTR on the topic. Thanks.
  22. I thought Its a honda Fit as well. So this doesn't come with the 7 speed auto CVT?
  23. And also the Primera GT's they built in 96 - 99 were amongst the very best when it comes to handling, driving feel and reliability. The equipment they provided with that car was un-matchable for european rivals at the time. Back to the original topic if I was in ur shoes I would go for the honda; provided that it has auto CVT box. Try to do some research on how to maintain the CVT gear box if u r going for that. Cheers.
  24. I did not say ALL the exotic car buyers are playboys. I said MOST!! I know there are some people as u mentioned. To GTAM About the "huge amount of money thingy" I'm not only talking behalf of me. I would say my posts represent "an average car buyer" from UK. Yes owning a car is a huge expense for any family with an average income. The number of small cars on the roads today have increased dramatically over the past few years. U could get a 2nd hand BMW/Audi/Benz for a brand new Corsa/Clio money. Which will be "prestige" according to u. But does that happen all the time? NO. People who take that option are a minority. Buying a new small car means free 3 year service, No MOT for 3 years, cheaper insurance and tax, better on fuel. So number of people consider that option rather than getting a used BMW or an Audi and paying for its maintainance, MOT, tax and insurance. If u see the size of the so called small cars manufactured today, they ain't any smaller than an ordinary 5 door hatch. The small cars are built bigger to easily accommodate 5 adults. Small cars are more or less a family cars nowadays. Like the new Fiesta which has taken over the market of its big brother Focus as well. Do u think if running costs was not an issue people would ever go for a small car as a family car? When an individual wants to buy a car; the first thing comes to his/her mind is how is it gonna be to live with it! Not how cool am I gonna look in it! U get what I'm saying? Its just like people go for toyota. nissan since they are cheaper to run in SL. In the UK they go for a brand new small car or a slightly used very reliable cheap to maintain japanese or european car. I was talking to a trader the other day and he was saying that buying a 2nd hand japanese car is increasingly difficult; reason being people who owns them tend to keep the cars for a longer period of time due to their unquestionable reliability. Cars like Honda Civic has a very good 2nd hand market compared to its European rivals. Mainly due to its reliability and the build quality. Sales of lower medium cars have been usurped Superminis are the most popular cars in the UK after used sales in the sector overtook those of small family cars. During the first half of the year sales of B-segment models reached 1.11 million units – 0.2 per cent higher than sales of lower medium cars. The Fiesta is the UK's best selling used car According to data analyst Experian, which compiled the used car study, it is the first time in eight years that the lower medium segment has not been the nation’s best selling sector, although its lead has been whittled away in recent years. The Ford Fiesta is the UK’s best selling used supermini and was also the best selling used car overall during the first half of the year. The Fiesta notched up sales of 176,351 units, ahead of the Vauxhall Corsa with 154,224 units and the Renault Clio which followed with 111,762 sales. The Vauxhall Astra topped lower medium car sales with 167,080 units, the Ford Focus and Ford Escort were the next best-selling lower medium models. Kirk Fletcher, managing director of Experian’s Automotive division, said: “With growing levels of personal debt, higher running costs, increasing tax and pressures to reduce our impact on the environment, the benefits of a smaller car are becoming more apparent to car buyers. “It is not surprising that supermini sales have topped the popularity list in the used car world.” http://www.motortrader.com/26196/Supermini...K-used-ca.ehtml
  25. Yes there are many students who don't go to uni because of the loan. maybe u haven't met many, but I have come across quite a few... For ur information, I went to the university ranked 1 in whole of the UK by The Guardian for my field of study which is Mechanical Engineering. I don't know much about mickey mouse courses mate, maybe u could explain a bit..... Have u studied that? As about believing me, I don't really care u believe me or not, I couldn't care less.
