Gilly Posted August 10, 2014 Share Posted August 10, 2014 (edited) I am interested in this, 5th gear is crap and there is literally 500rpm difference from changing up from 4th. whats the final drive ratio, or will it just be a straight swap over from the c52 drive?

jayc-glanza17 Posted August 11, 2014 Share Posted August 11, 2014 what lsd's are there for the yaris gears?? it would be nice to go to shows at low revs, be cheaper too.lol Quote Link to post Share on other sites
5e colin Posted August 11, 2014 Share Posted August 11, 2014 there is 6 bolt and 8 bolt lsd available so what ever the outcome lsd can always be fitted :-p :-p Quote Link to post Share on other sites
jayc-glanza17 Posted August 11, 2014 Share Posted August 11, 2014 what lsd are they?? I love my cusco in my c52.. just be nice to sit at 70mph doing less then 3300rpm of their abouts.. Quote Link to post Share on other sites
daniel_g Posted August 11, 2014 Share Posted August 11, 2014 You wont need to swap the whole gearset over, you can just swap the 5th gear, the d4d is a C series box so the gears are interchangeable. Quote Link to post Share on other sites
jayc-glanza17 Posted August 11, 2014 Share Posted August 11, 2014 yea I know that dan, just wondered it cannot be that easy surely?? bearings must be different?? what sort of revs is the diesel gearbox at 70mph compared to the stock 5th Quote Link to post Share on other sites
rwdrev Posted August 11, 2014 Share Posted August 11, 2014 are the crowns a differnt size and can these be used on my lsd i have already? Quote Link to post Share on other sites
morgey Posted August 11, 2014 Share Posted August 11, 2014 5th could be changed separately. Youd have to use both input and output gear (drive and idler gear) from the yaris box and fit them straight back onto the starlet gearsets. There would be no bearings touched in doing that.If you wanted to change the whole gearsets I would just follow taggy's guide to fitting an lsd (hopefully yaris boxes run 8 bolt diffs so your aftermarket diffs will bolt into the yaris ring gear if not you'll need a 6 bolt lsd). And use it to fit an lsd to the yaris box and also to swap the bell housings over from the zz bell housing to the 4e bell housing as they will be almost the same.Thats the easiest way of achieving longer gears. Pulling differnet gears off and using them on the final drive set to make a box of your choice would be a lot of work and will require use of a hydraulic press and a lot of time and effort. (I know, im about to do it to change some selector hubs and shyncros on my bzr 6 speed box) Quote Link to post Share on other sites
5e colin Posted August 12, 2014 Share Posted August 12, 2014 yea I know that dan, just wondered it cannot be that easy surely?? bearings must be different?? what sort of revs is the diesel gearbox at 70mph compared to the stock 5th at 62mph the yaris d4d box doos 2200rpm and morgey if they where to use the whole gear set then it aint that hard gears can stay on shafts exept 5th setup !!!! i will have to make a tutorial on the d4d box when i rip another 1 apart Quote Link to post Share on other sites
Gilly Posted August 12, 2014 Share Posted August 12, 2014 at 62mph the yaris d4d box doos 2200rpmand morgey if they where to use the whole gear set then it aint that hard gears can stay on shafts exept 5th setup !!!!i will have to make a tutorial on the d4d box when i rip another 1 apart A tutorial would be awesome! :-) Quote Link to post Share on other sites
morgey Posted August 12, 2014 Share Posted August 12, 2014 pulling 5th off can be a right royal pain in the ass though, i broke 2 sets of pullers getting mine off. and anyway if they want to use the whole gearset then just change the bell housing, that way you dont even need to remove 5th gear anyway.

jayc-glanza17 Posted August 19, 2014 Share Posted August 19, 2014 definitely need to look at this now.. japfest2 their and back was a killer sitting at 70mph.. whats best or easiest way to do this. does anyone know if my cusco lsd would fit the yaris gearset? Quote Link to post Share on other sites
daniel_g Posted August 19, 2014 Share Posted August 19, 2014 Even though 5th can be a cunt to get off id say just swapping the 5th would be the easiest way to go about it. Can just take the end cover off the box and do it with the box still in the car. And you dont need to change whole gearsets or diffs etc. Quote Link to post Share on other sites
rwdrev Posted August 19, 2014 Share Posted August 19, 2014 any part numbers for this yet? Quote Link to post Share on other sites
