trigger88 Posted October 25, 2016 Share Posted October 25, 2016 Hey ya guys just wondering how many revs your sitting at when doing 100kph. I'm doing about 3900 in fifth which seems really high. car is glanza v 1996 sitting on 17's with 205x40 tires. Just want to know if this is normal or if something is different. Ie does it have a different dif possibly or is the counter reading wrong or something else? Use the vehicle for 1000km plus road trips. Want to make sure car is not over working and burning to much fuel. Cheers Quote Link to post Share on other sites
funny onion Posted October 26, 2016 Share Posted October 26, 2016 100kph is about 62mph according to google? seems a bit high to me. Quote Link to post Share on other sites
5e colin Posted October 26, 2016 Share Posted October 26, 2016 Turbo box a100 is 3000Na box is 32/3300 sounds like your stuck in 4th use a multimeter to check what real rpm you doing Quote Link to post Share on other sites
trigger88 Posted October 26, 2016 Author Share Posted October 26, 2016 Yep is the turbo model. Sorry don't understand what you mean is stuck in 4th? How do I use the multimeter to check? Cheers for the help. Quote Link to post Share on other sites
morgey Posted October 26, 2016 Share Posted October 26, 2016 Trd gearset maybe? Thats very close gearing or incorrect rpm reading Quote Link to post Share on other sites

Ralph1 Posted October 26, 2016 Share Posted October 26, 2016 My NA EP91 sits on 3000/3100 at 100kph. Pete Quote Link to post Share on other sites
gorganl2000 Posted October 26, 2016 Share Posted October 26, 2016 does the car sound as if its actually revving at 3900rpm when your speed is 100km/hr? Quote Link to post Share on other sites
trigger88 Posted October 26, 2016 Author Share Posted October 26, 2016 It does sound pretty high. Driving on very smooth asphalt engine noise is definitely there, unlike my golf GTI which is noticeably far quieter (probably because its a golf) but when the golf is at 3900 it is far louder than starlet. Is it possible that the counter is having problems? It seems to read fine at idle approx 1000rpm. At 50kph in 4th gear reads around 2100rpm. Ive had a look round on the net, found that normal c56 gearbox has fifth ratio of 0.815 and diff ratio of 3.72. However have seen that the c52 box is a common straight swap. This box 3rd and 4th ratios are different but fifth is still the same. correct? If so i dont give a toss which box is in it, my question is are the diff ratios different? Has someone stuck a GT c52 box in my glanza v changing the diff ratio of 3.72 to something higher? say like 4.3? If this is the case I imagine its one hell of a job to swap out which Im really not keen for. Hope that im wrong with the possible changes in gearboxes. Is there an easy way of telling which box I have? and is there an easy way of telling if I have an after market diff with a high ratio? really appreciate the knowledge and quick responses.

gorganl2000 Posted October 27, 2016 Share Posted October 27, 2016 does you rev counter needle bobble about or move smoothly as you accelerate? what does it say at cold start?...what does it say at limiter? i think around 2500rpm in 5th gives about 80km/h-----can someone verify that???---my car is not daily anymore., so that's based off my aging memory lol Quote Link to post Share on other sites
trigger88 Posted October 27, 2016 Author Share Posted October 27, 2016 Moves smoothly during accelerationReads about 1800 from initial then calms down to about 1000 Quote Link to post Share on other sites
trigger88 Posted October 27, 2016 Author Share Posted October 27, 2016 Is there an easy way to test it, mate has a hoist I can throw it up on if need be, but would prefer to do it with a multimeter, have had a look around on Youtube but for the glanza seems difficult could anyone upload a clip that works for the starbo or photos of their own vehicle with it being done. Im pretty sure you need a hertz reading function. Doing the math with tire diameter, I know I should be getting 2900rpm. Once again thanks for the knowledge. cheers Quote Link to post Share on other sites
fiddlersport Posted October 27, 2016 Share Posted October 27, 2016 Put a picture of the box Some one may have put the end casing off a glanza/gt onto n/a box ? Quote Link to post Share on other sites
morgey Posted October 27, 2016 Share Posted October 27, 2016 Stick a timing light on it to test if rpm matches dial. Some have a rpm readout. If its ok check speedo against a gps. If they match then its down to your box being modified Quote Link to post Share on other sites
morgey Posted October 27, 2016 Share Posted October 27, 2016 Ok so just had a thought whilst driving my daily. Cruised up to 60mph/100kph in 5th... nearly 4000rpm Its a 6 speed corolla.What position do you have to put the gearstick in to get reverse? Quote Link to post Share on other sites
trigger88 Posted October 27, 2016 Author Share Posted October 27, 2016 Reverse is far right down pretty sure its a five speed unless there is some special shift like on European cars ie lift the gear stick up or push down to access another gear. Sorry unfamiliar with a timing light could you please provide more detail cheers. Quote Link to post Share on other sites
morgey Posted October 27, 2016 Share Posted October 27, 2016 Ahh definitely a 5 speed then 6 speed is up to the left. Timing light is used to set the timing, you clip it to the ht lead and it flashes every time that cylinder fires. However some timing lights also have a digital readout that displays the Rpm. Its an easy way to check the rev counter agaisnt actual rpm Quote Link to post Share on other sites
trigger88 Posted October 27, 2016 Author Share Posted October 27, 2016 I have a spare rev counter lying around... which bloody wire do I tap into on the dizzy for the sender wire? photos would be appreciated cheers. Quote Link to post Share on other sites
trigger88 Posted October 27, 2016 Author Share Posted October 27, 2016 Also what other connections do I need? Earth? positive connection on battery? negative connection for battery? Quote Link to post Share on other sites
