m running a bp+t on a cable g series. diff keeps breaking

[fastivab6tg25mr]

95egt bp+ big 16G mitsu turbo on 13psi. centerforce clutch, cable g25mr trans, 1/4 mile 13.2@109


i have destroyed 2 diffs in 7 weeks after my stock gears were replaced . has anyone had a problem with after market diff gears shearing off teeth?

i had my stock diff gears replaced when the trans was rebuilt 7 weeks ago. 2 weeks ago they sheared off 2 teeth 180* from each other. trans shop called it abuse so i had to pay $200 (they warrantied the labor but not the parts) and it just snapped again... i drag race my car every week and the stock trans and diff gears lasted 2 years with just a few chips out of the gear faces of one of the spiders. any imput is helpful

Some member here are doing the Toyota E153 gearbox conversion instead of spend a lot of money on repairing their busted g series. Here is the link to the thread http://www.wihandyman.com/forum/showthread.php?t=45016

At what rpm does your car come on full boost with the 16G & what is the response like?

The E153 wont fit in a festiva.

My bad didn't kno it was a Festiva. I saw 95egt bp & thought otherwise.

it doesnt fit in any mazda / ford car. You have to use a big ****ing hammer and beat the **** out of the frame rail or be a civilized person and cut and then box/weld everything shut.

why not put in an lsd that can take more abuse?

he says hes shearing teeth off the ring gear, an lsd wont stop that.

He's shattering / shearing teeth off the spider gears. Ring gear is fine.

LSD is the way to go.

thanks for the replies... seems there are alot of the same faces(you know what i mean) on different forums.

Did you have the preload set on your gear boxes? Too much play in the diff is bad.

Ive blown up plenty of g series, All diff failures with 200whp/220tq, daily driven hard w/ some track time as well, mfactory lsd goes for about $650, the next weak link will be 3rd gear, which tends to strip teeth.

thanks... i guess ill look forward to that...lol
