    as long as your not stalling then it should be fine... kung 60kph dapat mga 2nd o 3rd gear ka pa lang nyan pero since mahal na ang gas oks lang yan for cruisin speed. put it in 4th gear para di masyadong mababa yung idle mo.. tatalon lang yan ng mga 3K-3.5K RPM

    I think it's OK for your car. I do that too, mine is 2.0 liter gas Innoval

    That's ok, kaya lang parang taxi ah... If gas-saving is the objective, puwede siguro hanggang 2,500 and your mileage will only go up very little. Try it. Also, shifting at 2K or less is not always advisable, like when you need power to pass or go uphill.

    diba most economical na driving is when u reach 60-80kph at highest gear? yung nakasulat sa manual ng mga kotse namin pati sa ilang libro na nabasa ko...

    Eh... kaya pala... sports transmission yun. My RS does only 60kph at 2000rpm in 5th also.

    theres really no "correct" top-gear rpm * X speed. that depends entirely on the gearing specified by the manufacturer for your particular car.

    2,000 rpm * 60 kph at top gear is pretty high... meaning that your car is geared pretty short overall... that would mean you'd be at 3333 rpm at 100 kph. but if that's what you're getting, then it's normal (unless you changed your wheels to larger-diameter ones, in which case it's not stock anymore but it won't harm anything).

    as to the ideal shift points, as long as the engine doesn't lug, okay lang. you can shift at 1,800 rpm even as long as the engine rpm doesnt lug at upshift. sa diesels, you can shift at practically any rpm hehe.

    Your SiR wants you to rev to get those 160hp!! Usually NA engines have narrow power band so gear ratios has to be close so that you don't drop below the power curve when shifting while you're on full throttle.

    What if you shift too low and the engine doesn't have enough torque so you have to compensate by pressing the gas pedal further... doesn't this waste more gas?

    im not sure but i try to keep my engine "happy" by shifting not too low and not too high... un tamang tama lang. i shift at around 2-2.2k pag overtaking 2.8k to 3.0k

    Yeah, 60 km/h at 2000 rpm is rather high. Regular 1.6 cars usually have 1800 rpm when traveling at 60. SiRs are real revvers and not exactly made to be cruisers. The engine is high on power but low on torque so the gears must be closely spaced for better acceleration.

    Psylocke,

    not really. if the rpm is too low and torque is lacking, the revs will rise very slowly even if you mash the throttle. if you hadn't upshifted, the revs would have been higher anyway, and higher revs always drink more gas than lower revs.

    Well, with short-geared engines, shifting at 2k isn't that hard... when I'm just diddling around, I'm usually in fourth gear between village humps, going at 40kph... fifth gear on longer roads at 60kph, but my engine makes over 100 ft-lbs of torque at 2000rpm already, not like the Honda. The SiR really isn't lacking all that much in the way of torque, but it can feel sluggish sometimes at low rpms. When I'm driving the SiR, I usually shift at 2.5k, even when going slowly.

    If you feel you don't have enough torque to shift at 2k (and honestly, when merging into traffic, it's sometimes dangerous to accelerate this slowly), 2.5k is all right, as long as you settle into your cruising speed after and lift off.

    For me, it's just finding your car's balance of the lowest revs which will give you acceleration with the least pedal pressure.

    pano naman ung 2nd gear kagad from stop. hindi na ginagamit ung 1st gear. barakada ko ganon e, sabi niya ayos lang daw un kasi diesel naman daw.

    nung araw na manual pa drive namin, hindi ko pinapalampas ng 2k rpm to shift. Kahit pa Civic (EK) sya, in fact sa 'rolla is even lower. As long as hindi parang hirap yung makina, and by that, other factors such as inclines/load should be considered. If you are trying to merge sa Highway traffic, its better to have your car reach cruising speed as fast as possible

    for a/t depende yata sa driving style eh - cant really tell when an A/T shifts but its at least 120kph * 3000rpm when cruising.
