  1. Just so happens I had a run against a SSS this moring in my 03 stivo (both cars stock from what I could tell). Standing start from traffic lights, uphill where two lanes had to merge into one. This guy had been driving like an idiot swerving in and out of traffic so I thought I would show him what a real performance 4cyl can do. Both of us lauched with low revs then floored it. Race was dead even until I hit lift in first, between 6000-8000 rpm I put about 2 car lengths between us, by the time I got to the rev limiter in 2nd the SSS would have been about 10 car lengths back. I thought maybe he had given up and this was why I was so far in front, but as I backed off and slowed down he came charging up behind, so I don't think he had. By the way, I traded an N15II SSS to by my Sportivo, so I knew the sportivo was going to be a fair but quicker.
  2. Negatron, I may be able to help with some of your questions, but first, why are you looking for headlamp protectors? Headlamp protectors on modern cars are a scam. They were introduced when cars had headlamps with glass lenses that could be easily chipped or cracked. Todays car headlamp lenses are made from polycarbonate usually LEXAN (i.e similar stuff to that used for bullet proof windows). You would need a rock the size of a cricket ball to hit the lamp while driving at 100km/h to break the lens. By the way headlamp protectors also reduce the light output of the lamp and reduce its ability to dissipate heat (i.e more likely to melt). HEADLAMP PROTECTORS ARE A SCAM!! Regarding opening up the headlamp. The lamp lens and housing are attached to each other with clips and a sealant. The sealant may either be a hot melt or a silicone sealant, I'm not sure what is used for the corolla lamps. As metonied on this forum perviously if its holtmelt then you could heat the lamp up to over 80degC and pull it apart, but it is very unlikely that you could achieve a good seal when you put it back together again. If its silicone then you won't get it apart at all. Hope that helps.
  3. Guys (& girls) There seems to be a few people on this form making statements about this topic without really understanding what they are talking about. :( So I thought I might try to clarify the meaning and realtionship between power and torque, if anyone is interested read on. Torque is the amount of twisting force an engine generates, or how strongly it can twist the crank shaft. Power is the amount of work and engine can do in a given amount of time. Talking conceptually Power = Torque x RPM Often you hear people say that it is torque that determine how hard a car can push you in the back under acceleration and this is ture tue a certain extent. Is what people fail to appreciate is that it is torque at the wheels that determines how hard a car can accelate (also weight needs to be factored in, but we will come to that later). Is what needs to be considered is the role of gearing. With a gear box the amount of power you put in is the same amount you get out the other side (excluding any loss due to gear box efficiency). A gear box is about trading torque for rpm. So you can get more torque out the other side at a reduced RPM or more RPM out the other side with a reduced torque. So to give an example, lets say you have 2 cars one is a commodore travelling at 50km/h with the engine at 3500RPM making 300Nm of torque. The other is a corolla sportivo travelling at 50km/h with the engine at 7000RPM makeing 150Nm of torque. For this to occur the overall gear ratio (gear box & diff) of the corolla is double that of the commodore. The gear box in the corolloa is trading RPM for torque at twice the rate of the commodore. Thus both cars have identical amount of torque at the wheels at identical wheel RPM, and thus (assuming the cars weighed the same) would accerate at the same rate or push you in the back with the same force. So is what determines how hard a car accelerates is torque on the road divided by weight, and torque on the road is more directly related to power (as this considers both toque and RPM) than torque alone. So to put this into persepective. The reason why relatively low torque engines like that in the corolla sportivo can give stong acceleration is that they can make torque at such a high RPM that you get lots of power that can be geared down to give lots of torque at the wheels (remember power = torque X rpm). So that's it. I hope it was informative and/or helpful. B)
  4. Well assuming the 235Nm is made near the top of the rev range, say lets say 7,800rpm then you would have approximately 183kw B)
  5. This sound to me like to opinion of some 50+ year old who would be much happier in a V6 auto family sedan. Anyone who doesn't like the sound of a high-tech 4cyl at 8000rpm is obvisouly on a completely different page to all the people on this forum. OK the sportivo has it's limitations, low torque at low revs, open front diff etc. but you get way you pay for, and this this case you get a lot for your $30,000. If there is another car that comes close to the sportivo on performance, features & driving enjoyment for less money then go out and buy one.
  6. Along the same lines as this post, today on Burwood Highway, just near Station Street I saw I white sportivo at full roar :) (1st gear & 2nd gear), it had red plates, c-one spoiler ends, stickers one the front doors etc. It sounded more like a big bore motor bike than a car ;) . Was it anyone on this forum, if so what mods did it have?
  7. I'm another one with this problem. The front left suspension is noticeably louder than right over even small bumps in the road. On the other end of the scale I have had instances of going over speed humps at slow speed and hearing a loud CRACK :o from the front left. Upon inspection not a single mark on the bumper lip, underbody etc. the noise has to be somewhere in the front strut, or suspension/steering linkage. I will have it checked out at the next service.
  8. Hey, I used to go to Monash, to study engineering. In those days I drove a slightly rusty escort RS2000. How do you guys aford to drive Sportivo's while at Uni
  9. I traded in a Series II N15 Pulsar SSS in to by my Corolla Sportivo. Having driven the SSS (stock) for 5 years 100,000 kms, then changing to the Sportivo I can say with no doubt that the Sportivo (stock) is substantially quicker. From 2000-6000 rpm the SSS may have a slight (marginal at best) advantage, but from 6000-8000 rpm the Sportivo is in another league, the Sportivo would pull away like the SSS was standing still. If people start talking about mods then I guess things change. If you throw $3000 at a SSS it will probably out run a stock Sportivo, but throw the same $3000 at a Sportivo and put it up against the modded SSS then again the SSS doesn't stand a chance. That's my 3 cents worth!
  10. Regarding the HID (High Intensidy Discharge) issue. As an engineer involved in the automotive lighting area I thought I should let you guys (and girls B) ) know that the HID kits being discussed in this topic are not ADR (Australian Design Rule) approved, as a result it is most likely that by fitting such a kit to your car you would make the vehicle un-roadworthy. This may or may not be a concern to you but it's always best to be fully informed.
  11. Sorry E-Gene I had never seen this animation before and wasn't aware that it had been posted before. My pilosophy: a lift session a day helps you work rest and play! :D
  12. No need to post file, I found the internet link where it came from. VVTL-I Link Download, unzip and check it out :)
  13. Guys, I have come across an animation explaining and showing how vvtL-i works. It is a zip file 440kb. Can someone tell me how I post it so you can all check it out.
  14. Having worked for a company that painted plastic bumpers for Australian auto industry I can tell you that the vast majority of bumpers on new cars are made of polypropylene (PP). I have no reason to beileve that the corolla/sportivo bumpers are any different. This being the case if you want to do a repair to a bracket the best option is to heat the plastic (not too hot or it will burn) and just push/weld it back together. 03MikeSportivo you mentioned the grill, these are usually made from ABS (acrylate butal styrene or something like that) but can also be welded just by heating up. By the way PE isn't polybuttlene it is polyethylene, sorry to be a smart **** ;) Hope that helps.
  15. Check out www.tomsracing.com.au they seem to have a lot of C-ONE stuff for sale. From their website it looks like they have a showroom at 2 Cottage St Blackburn VIC. I am planning to go there and check it out tomorrow. Has anyone else been there?
  16. Good work ZEEROLLA ;) Toyota seem to acknowledge that there is an issue to be addressed but don't mention anything about what the issue is. Did your email talk specifically about one or more issues or was it just general. To put it another way what specific problem do do think the 'action plan for resolution' is going to address?
  17. Guys, add me on there too. 8400rpm 03 silver Sportivo VIC south eastern suburbs
  18. Great to see all you guys out this afternoon. TRD 141 that quad exhaust looks sick, I was suprised at how well it integrates with the look of the car, if someone didn't know any better they would think the car came out of the factory like that. Look forward to seeing some photos, although photos can't really capture the sound as three sportivos hit lift as they drive past. Look forward to another meet/cruise.
  19. I'm keen too, although I can't guarantee that I'll be availiable. Hopefully I'll be there.
  20. Don't get me wrong!! I'm not suggesting that the Sportivo could have taken the Clubsport, but I think the HSV driver was expecing to leave me in his dust when he took off in the way that he did, but was supprised to see the corolla still next to his rear bumper. I know if I had paid $60,000 for a 'performance' V8 sedan I would expect to easily blow off a corolla.
  21. Nah, not my car in the picture. Althoug strangely enough mine does look exactly the same :D The picture is a cropped version of one of the photos from the original Toyota media release for the Sportivo.
  22. My Sportivo has about 13,000km on it and I have the same issues everyone else here, eg noisy brakes when reversing, mild gear cable rattle etc. Unfortunately I don't have any inside info on any of these issues or the ADR/recall issue. The company I work for supplies parts that go on the Australian built Toyotas (i.e. camry & avalon) so the engineers at Toyota we deal with are focused on these models and in general don't have anything to do with the import models (i.e corolla etc.), but if anything does come up I will be sure to post it here. By the way I'm also from Melbourne B)
  23. shaohaok, Don't want to give away exact details, but I work for one of the major tier one automotive suppliers, we manufacture original equipment for Toyota, Ford, Holden and Mitsubishi.
  24. G'Day guys, I've had my for Sportivo for about 12 months and have been visiting this site for a while and decided it was about time I had some input. On the way home from work today I had run short run against a VY clubsport (260kw, auto trans I think), anyway in 1st he slowly pulled way about 1 car length, until I hit lift at which point I pulled about 1/4 of a car length back. At that point we caught up with the trafic in front of us and had to back off. But I think the HSV driver was very suprised to see the corolla still next to him at 70km/h. Anyway, one thing I have been curious about reading all your posts the last few months, what do all you guys do for a living? I'm an engineer in the automotive industry.
