Chops Posted July 13, 2014 Share Posted July 13, 2014 Hey all, I completed quite a long journey today, but found my ears were bleeding from all the constant high revs of motorway travel lol. for a car labeled as being a gt (which I presume stands for grand touring) its not that pleasant to monster along in the fast lane for too long. I was considering finding a taller final drive from a different version of the same gbox, but i do like being able to shove it in 5th at thirty and burble around town, so i came to the conclusion that more gears were needed. Can anyone give me advice as to the pros and cons of the six speed version box ( out of a high spec late 90s corolla arn't they? ) and what id need to do the conversion please, cheers!

richardc9052 Posted July 13, 2014 Share Posted July 13, 2014 6 speed isnt that much lower than a 5 speed. only maybe 3-400rpm.. Quote Link to post Share on other sites
Chops Posted July 13, 2014 Author Share Posted July 13, 2014 6 speed isnt that much lower than a 5 speed. only maybe 3-400rpm.. at what speed? i dont know what the ratios are for each. isnt the lsd box a shorter final drive as well? Quote Link to post Share on other sites
5e colin Posted July 13, 2014 Share Posted July 13, 2014 its only the mr2 spyder ( euro ) that has the lower cruising rpm !!!! ( 6 speed ) a yaris d4d is perfect 2200 at 100kph or starlet box with a yaris 5th will be around 2500 +- Quote Link to post Share on other sites
Chops Posted July 13, 2014 Author Share Posted July 13, 2014 do you need a conversion plate, or does the bellhousing match up to most toyota engines or something? presumably custom shifter parts would need to be made as well. Quote Link to post Share on other sites
5e colin Posted July 13, 2014 Share Posted July 13, 2014 (edited) you knead to swap bel on both boxes and cables to ( 6 pot ) yaris d4d internals can be fitted in the starlet box with no isseue i also bean told the 6 speed internals will fit inside a 5 box when using the 6 speed outer cap !!! where 5th and 6 is i personally cant confirm the last part but thats something i have bean told on another forum you can get 4efe g6 6 speed ( strait bolt on ) but 6th gear isnt any lower then starlet in 5th at 62mph Edited July 13, 2014 by 5e colin Quote Link to post Share on other sites
Dylanfarrell Posted July 13, 2014 Share Posted July 13, 2014 do you need a conversion plate, or does the bellhousing match up to most toyota engines or something? presumably custom shifter parts would need to be made as well.For which conversion? You can get a 6 speed out of the corolla g6 which comes with 4efe. Alternatively you can get the gear stack, diff and housing from a BZR and swap it into the bellhousing from a gt/glanza. Open to correction on this though Quote Link to post Share on other sites
morgey Posted July 13, 2014 Share Posted July 13, 2014 Corolla g6 4efe bolts on.G6r 4afe needs bell housing swappingCorolla Sr 3zzfe 99-01 needs bell housing swappingLevin/trueno bzr 4age needs bellhousing swapping.Corolla/celica tsport 2zzge needs bellhousing swapping. (£150) probably cheapest option tbhYou can notch you selector to allow for the extra movement needed for reverse (its besides 1st on 6 speeds) If you wanted to put the extra gear in to a starlet box you would also need both input and output shafts as they are longer. Along with the casing and all the other parts so theres no point in doing this as it is way to much hassle. Only thing im not sure about is which cables and the mounting brakets on the box you would need. Quote Link to post Share on other sites
Gainzy Posted July 14, 2014 Share Posted July 14, 2014 Sounds like alot of work and you need to know what your doing for the sake of an extra gear you can live without, a high top end big power engine yes but a 1.3, can't see much benefit when you could spend the money on some ear plugs or an ipod haha or even an exhaust bung stock air filter I jist think is an extra gear worth the time and money.

morgey Posted July 14, 2014 Share Posted July 14, 2014 They have been know to strip 6th gear in levin/truenos running near stock power. But stu was running 350+ in his with no problems for years. Some do have lsd's yes (Bzr stock and an option on every other model 20v) best way to check is make sure theres a plate across the holes through the driveshaft holes if theres a 10mm pin its an open diff.

richardc9052 Posted July 14, 2014 Share Posted July 14, 2014 3rd gear grinds in a lot of them. Caused by people who don't know how to drive getting behind the wheel. They are a soft ish box but if you double clutch and rev match (becomes natural after a while) the box will be fine.. Quote Link to post Share on other sites
morgey Posted July 14, 2014 Share Posted July 14, 2014 Could say the same about the 5 speed tbh. 2nd and 3rd 5th have all had grinding issues on my 5 speeds. 6 speed I've got a 2nd gear crunch that im sorting out. Like you say it depends how you drive and if you give the synchro's time to do there job Quote Link to post Share on other sites

5e colin Posted July 14, 2014 Share Posted July 14, 2014 yes ^^^^^ 195/50/15 im trying to buy a yaris d4d box , if i find 1 cheap ish but there freaking waaaaay overpriced !!!!!! Quote Link to post Share on other sites
morgey Posted July 14, 2014 Share Posted July 14, 2014 Ill let you know what mine does when its in my corolla. Your mate could have trd final drive if its different from mine. However iirc mine wasnt far from 20mph per 1000rpm Quote Link to post Share on other sites
Dylanfarrell Posted July 14, 2014 Share Posted July 14, 2014 (edited) yes ^^^^^ 195/50/15 im trying to buy a yaris d4d box , if i find 1 cheap ish but there freaking waaaaay overpriced !!!!!! D4d boxes are all expensive because they fail so regularly and they're the same box in nearly all the D4D's like avensis and corolla Oul lad has a D4D Auris and the first gearbox blew up and cracked the housing. Bought a second box and had it professionally rebuilt to be sure it was A1 going in and within a few months that blew as well. On his 3rd box which he bought refurbished with warranty in exchange for his broken gearbox. Hopefully this one lasts a little longer lol Edited July 14, 2014 by Dylanfarrell Quote Link to post Share on other sites

Dylanfarrell Posted July 15, 2014 Share Posted July 15, 2014 do you still have the 1st box i will take itThat was given in with the second box in case they needed any parts for the rebuild as far as I remember. I'll ask him in the morning what he did with it. Quote Link to post Share on other sites
Neversimple Posted June 19, 2018 Share Posted June 19, 2018 Waking up an old thread I know but recently discovered that my Glanza came with a 6 speed box it is not far from Standard still to my knowledge should I be concerned about the gear box going at some point in the near future?
