hey guys, this question has probably been talked about before but i dont think it has for the corolla sportivo in particular...

in normal driving i shift at around 3.5k when cold and 4k when warm.

in thr manual, the recommended shifting speeds are as follows:

1st to 2nd - 30kph

2nd to 3rd - 40kph

3rd to 4th - 65 kph

4th to 5th - 72kph

5th to 6th - 80kph

knowing this, is it ok for the gear box and/or engine to be cruising on 6th at lets say... 50kph or 60kph?

Fuel efficient yes, but in the long term, going too high a gear at low speed would damage the gear box...

atm, i cruise in 4th from 50kph on a straight road and 3rd on an incline...

anything below 40kph i do 2nd and 1st bloew 20kph...

also i don't really use 6th until i hit around at least 80 to 90kph

whats your opinion guys?

cheers :)

You won't damage the gearbox, the recommended shift points are more for keeping the engine in it's most efficient zone. You can run the car down to 40-50km/h in 6th and just burble along but if you put any sort of load on it then downshifting would be essential so the engine doesn't lug.

Crusing at 60km/h or less you get better economy being in 5th instead of 6th. At 60km/h the difference is stuff all though.

Cruising wont cause any damage to the box, unless you don't have oil in it :P

Just listen and feel you car, if it feels like you are go to slow for the gear you are in and you cant feel any pull downgear. its pretty simple dude.

Basically. It's to do with engine load, as Hiro pointed out. The more load you put on the engine the more fuel will be used. In your example of cruising at 60km/h in 6th when you try to accelerate you require more throttle than you would if you were in 5th.

I don't wanna sound too negative but you've made quite a few topics that are either have already been covered or are a bit silly. There is a topic for that (the stupid thread thread)

yeah ur right. Also ur probably not the only person that thinks I post silly topics online. But I ask these silly questions becuz I really don't know or need information on some things. Just like everyone on these forums, they want the best for thier car. And this is wat it's about right? Helping each other?

Also I am one of few that probably spend thier time Reading thru the topics seeing if the topic is covered or not. (Yes all 2xx pages.)

I am sorry if I ask questions that r covered already but either I found the replies too vague or inadequate for me to understand. Yes I am a noob and I don't deny it

I don't blame u and1... Just let me get out of the "noob phase "(and hopefully it will be soon)

Everyone to thier own I guess... :)

cuz i've heard people say that travelling too high a gear in low speed will damage the gearbox, i wanted to ask for people's opinions here

maybe each car is made differently to another?

also my previous car had only 4 gears, so i drove it much differently than this one. just trying to learn whats best to make the mechanicals last longer

      1999 Camry Driver's door locking hatch issue

      It's possible that it could be something fouling or dirt build up, dry, or a broken mechanism, so have a look and give the mechanism some lubrication, most likely though, it'll be the actuator. I found one for a good price on Ebay, $25 delivered: Front Door Lock Actuator Right Side For Toyota Camry 1997-2001 | eBay

      Query about the correct rotors for 2006 ACV40 Camry.

      Hi, I'm looking at a set of front rotors for an ACV40 2006, 2.4L Camry. I got a good price on some RDA's at Sparesbox. However both RDA8112 and RDA7686 show as for my car and I'm wondering what the difference is and if there were changes to the rotors during the model production. So does anyone know which rotor is the correct one? Many thanks in advance.

      It's a simple solution though? Already laying down 60k for a RAV4, so what's another 1k on a phone to make everything work seamlessly? 👍

      Your solution is akin to suggesting that switching to a different car manufacturer would resolve the issue. However, not everyone shares the same enthusiasm for using an iPhone as you do.

      Turboed Corolla Overbuilt?

      that engine will be fine, the rods are the main thing to be concerned about. The 2860 is a decent turbo for the 1zz but in this day and age I'd go for a G25-550. The injectors might be on the small side, we run DW1000's. You need a full length injector, the shorter injectors with adaptors like ID1050x dont fit the 1zz head. You don't need an aftermarket intake manifold, if you do go down that path, avoid the CNC innovations unit, it's garbage. Do the boost control with a MAC valve and control it with the aftermarket ECU of your choice, I use Link stuff on most of my builds with the G4x Storm as the minimum. I also wire a fuel pressure sensor and oil pressure sensor to the ECU in my installs. Use a decent intercooler, the better cores (ARE, PWR, Garrett, Vibrant, Plazmaman, Hypertune) work a lot better than the chinese stuff like Aeroflow. a 450x250-300 fits fairly well with custom end tanks to route the cooler pipes through next to the radiator Don't forget about the clutch and gearbox. These days I like the Uniclutch twinplate, Above 300whp you'll want to think about upgrading the 3rd and 4th gears in the box also with the SSC (Hollinger) gear set and install an LSD of your choice. If you're going to give it a hard time, you'll also want an oil cooler. I like the HKS thermostat type sandwich plates and setrab or mocal oil coolers with -10 speedflow fittings/lines (Chinese AN fittings neck down to a lot smaller internal diameter in their bends, not great for flow) You'll also want to think about brakes, Celica or Sportivo front calipers will bolt on with sportivo discs as a starting point. To have somewhere like Tunehouse do the work you'll want to budget somewhere between 20-40K

      Camry Touring 2010 Fuel consumption 15.2L/100km. Normal?

      I did the mathematics myself regarding costs vs benefits for fuel injector cleaner. I have changed from 91ULP to 95PULP and 98PULP. Price difference can be about 13 -20 cents. Compared to 91ULP, Premium quality fuel should have a better quality additive package designed to have superior engine cleaning capabilities so the engine can perform at their best.

      "Fuel injector cleaner is a waste of money" Only if you by the cheap crap if you use LiquMolly a German Product it does work and you won't waste your Money.
