  1. Where is the $8,000 to $10,000 estimation mark coming from? Is that because of the gearbox? I am interested to see what makes up the bill for the car that has 130000KM.. because everyone of us might need to be ready for that bill
  2. Guys, I was on a KIA 3.5 V6 rental van (similar to Tarago size) in Tasmania mountains. To be honest, the understeering actually is very annoying. We are not driving very fast because we got many passengers sleeping. The van just refuses to turn even at slow speed. I am very suprised Looking at the tires, it is thick and narrow as well.... so driving a van requires you to slow down much more !!! so if you switch from a car to a van, you have to readapt the driving style
  3. I love this, unfortunately, it does not fit on my car

  5. which suburb do you live? cannot understand why people stole from a Corolla !!! This country is full of thieves In Chinese we have a saying "People steal $$ from a beggar's bowl"
  6. John, your one is already good enough, The adjustable is more for me on the track.. Front Struct brace will increase understeering, I cannot notice anything on the street driving. I can notice some on the track only on high speed corners (probably I am using coilover, it is not that noticable) explains the advantages of struct braceI personally recommend you dun buy the front struct brace untill you finished enjoying your rear sway bar.. There is no local supplier so far for this so far, although we want to support local industries
  7. $4XX including installation.. it is 20mm adjustable..it uses the middle axle beam to hold one part of the bar as well The handling is far superior than that in Cusco. They actually manufacture for you on the day !!! here is my picture

    Steve, thanks for fixing the CSS, max-width will do the trick.. I finally made the profile picture working, it has to be 200px

    new site

    My original signature automatically converted to embedded videos, which I don't want Took me a while to change my signature back to hyperlink. I have removed the http part of the link.. If it still does not work, I have to convert to IP address !! Not to show off, since I am a programmer (not php), this is my input... look at the left for all our profile pictures, the images are all getting blurred, using Firebug, in css file, http://au.toyotaowne...ss/prettify.css line 243 You are setting the height and width over there, which makes the images blurry. and in other pages, you are using a different size This programming technique will resize the image and make it looks bad... The best technique is using a dynamic page to generate the image at run time, having the width and height specified at the top of the url.. example will be thumbnail.php?width=90&height=90&imagepath=encryptedpath Now, I need to reupload my profile picture, and find it not working!!! Anyways, I like the new site. Just require further polish and it will fly !!
  10. what exaction location is it in the nation? The sun looks very good, I am assuming it is sunset?
  11. they are not cheap, but very light and looks very hot, and I think you need some camber at the front
  12. can you share how to change the lights on the dashboard?
  13. Most of you probably know about the difference between 421 and 41 exhaust manifold differences, but do you know this? This article is quite useful if you are considering changing header configuration The Mazda Skyactiv engine produces the highest compression ratio of 14:1, one of the design is using 4-2-1 exhaust mainfold instead of 4-1, the explanation is quite interesting Surprisingly, Mazda uses a very conventional approach to do that: a long, 4-to-2-to-1 exhaust manifold. On a typical inline-4 cylinder engine with short, 4-to-1 exhaust manifolds (the first picture), once the exhaust valve of Cylinder 3 opens, its exhaust pressure waves (grey area) flows through the short manifolds to the exhaust valve of Cylinder 1, which is at the end of its exhaust phase. This pumps some exhaust gas back into Cylinder 1 and becomes residual exhaust gas. When the engine is running at low speed (2000 rpm in the first picture), the exhaust pressure wave arrives Cylinder 1 early enough to cause high percentage of residual exhaust gas. As engine rev rises, the opening and closing of valves speeds up as well, thus the exhaust pressure waves of Cylinder 3 reaches Cylinder 1 at later stage, causing lower percentage of residual exhaust gas. In short, from low to mid-range engine speed the level of residual exhaust gas is pretty high for this engine configuration. In the case of Skyactiv-G's 4-2-1 exhaust manifolds (the second picture above), exhaust pressure waves from Cylinder 3 has to travel a long way to reach Cylinder 1, by the time Cylinder 1 has already, or nearly completed its exhaust phase. Therefore the level of residual exhaust gas is much lower than the previous case, especially for low to mid-range rpm. As a result, the Skyactiv-G engine attains lower temperature in its combustion chambers and allows a higher compression ratio to be used. Well, if the principle is so simple, why not others discovered already? It's not that simple, of course. One critical drawback of the long 4-2-1 exhaust manifold is that it takes relatively long time to heat up the NOx catalyst during cold start. In fact, this is exactly the reason why most modern production engines have abandoned this exhaust configuration - with the exception of high-performance engines which may use thin-wall fabricated stainless steel exhaust manifolds to compensate for its extra length. On cost-conscious mass production engines, cheap cast-iron exhaust manifolds are still the norm. Its extra mass and surface area absorb a great deal of heat and delay the proper functioning of catalyst. This causes difficulty to comply with emission regulations. Article in http://www.autozine.org/technical_school/engine/Ignition_Compression.html#Skyactiv-G That also means that my car might not be able to pass emission test!! and I understand why my header is designed like this, the distance travelling in cyclinder 3 to cyclinder 1 is much more longer, producing less residual exhaust gas
  14. I think you need a plastic cover for the intake..not sure who can make it for you
  15. Rockdale in Sydney http://www.k-mac.com.au/ They do customised springs. Juvenile and I get my custom sway bar done there. Talk to Kelvin, the owner. He has my rear sway done few days ago It is a small shop, but the knowledge they got is expert in the industry
  16. To explain more, if you stiff the springs, I have read somewhere else that you can increase the spring by 20% without adjusting the valve in the coilover.. Please do research on this area as well.. If you are in NSW, I can introduce you a shop for you to ask instead of pedders.. I am no expect on this at all.. Superdave is, not me!!! MR 988, how much lower you want, your car is already hot, and you have to worry the guard inside the wheels as well after you lowered
  17. go to toyota tech USA or Europe web site I remember it is $15 for 3 days access in USA, and $8 for 1 hour access in Europe For Toyota USA, you have to search for TMC made (Toyota Motor Cooperation), because the USA makes corolla themselves and use a different ECU map and other components
  18. Taking the license plate looks so good, it is really a white chocolate feeling
  19. Thanks, bit disappointed after looking at this list I am looking for Subaru STI version of this car, TRD is very conservative and expensive
  20. I guess Pedders is right, because you now ask the shock to do more jobs that your spring The same theory goes to stock shocks with stock spring cut
  21. Thanks, Jeff for reminding I was shooting myself regarding my own words !!!! Correction: The front sway bar for ZRE is 25.4mm, not 16mm (to be confirmed) Whether it is 16mm or 20mm is really an experimental thing, and it is always a puzzle for me. At that time (september), I am still a beginner to track, skills are still yet to develop. Now I am still learning, but obviously, my skills are better than in sepetember. Now I can do quite consistent lap times, whereas in september, I cannot.. I have asked KMAC suspension for the thickness for FF car, he told me, 20-24... Looking at whiteline web site for their rear sway bars ZZE: 22mm AE92, AE101, AE82: 18mm VW Golf GTI: 24mm Ford Focus XR5: 22mm These number is just for reference, each suspension geometry is different, but ZZE, Golf GTI both using Torsion beam at the back and front struct, so the set up is quite close.. and I have no idea what is the spring rate they are using.. Also, I guess the ZRE has a really thick front sway bar (to be confirmed), I have checked the cusco front sway bar for ZRE, and the cusco ones has 30mm, checking at RHDJapan for 925 311 A30, the ZRE152N has original thickness of 25.4mm, so I guess our ZRE has the same thickness of 25.4 Some other factors also to consider 1. After I put front upper struct brace and front lower struct brace, the car starts to understeer more (I dun have these in september) 2. After I increase the thickness of suspension by turning the coilover, the lift off oversteer reduces 3. After I switch to semi slick, the lift off oversteer reduces 4. After you take off the back seat and front seat, the rear is more grippy 5. After you change the tyre pressure (I dun know how to tweat this in september) 6. Personal driving style 7. Camber? Too many factors involved only lap time will tell whether I have made the right decision
  22. I have replied already to the same thread in basically, unless u are tracking, dun waste money
  23. inspired by Juvenile regarding rear sway bar in http://au.toyotaowne...915#entry330915 I also decide to give up by Cusco 16mm solid sway bar and changes to 20mm adjustable solid ones but the design is like this, with rear ends of the bar attaching to one of the hole of the sway bar to make it adjustable (using sway links I guess).. and the torsion axle holding the bar on each side Price is close to $500 mark due to its adjustable nature (I know it is ripped off, but I dun have a choice, and since it is customised, it is reasonable for extra labour) This should fix the understeer problem after changing to Toyo R888 on track..(video at signature, not a good run) 16mm is too soft anyways when compared to other FWD cars with similar suspension design (Golf GTI, Ford Focus XR5, Corolla ZZE) Research shows 20 to 24mm is the reasonable thickness for our cars for aftermarket sway bars, but I am still testing AND My exhaust has rattle noise near the resonator when the engine revs at 600rpm idle, believe to have cracked developed.. My car is not even a turbo car, and the exahust has problems so early..sigh. How can I buy an expensive car to track !!!
  24. you should be looking for anti roll bar or hardening springs..rather than camber option, since you cannot do anything at the rear
