4wd transmission proplems, broke gearbox then diff and transferbox updated with broken gear selec Options

[tufy]

2 months ago i broke my gearbox, because i coulnt find stronger gearbox for daily use, i installed a 2nd hand standart gearbox which was slightly shorter... after i installed this g.box, traction of my car was more like front wheel drive.. (%60 front and % 40 rear. thats what i feel). then when i make a quick start i started to feel that rear diff. is slipping gears. after 3000 km i break my rear differential.
does anybody knows if ratio of g.box diff ratio and rear diffrential ratio change it make diff stress and broke easier. or my diff. broke from too much power.
simply;
does it make proplem in a 4wd car if i have shorter ratio gearbox without changing diff..
sorry for my bad english. and thanks for your help.

the stock E154-F isn't really that strong... it depends how you drive it, and if your using a launch controller than ya that trans is goingto get raped, first the rear diff will start to warp then the fluid in the tranny will burn and there goes your trans.

if you want to end this post do your research, get a damn bias rear diff out of any of the caldina's and grab the awd trans out of it as well

you cant say a trans can hold X power, its all about how you drive, my 5s-gte is only sitting @ 20psi on an E153 and i've already destroyed first gear prior to using my EMS's onboard launch control and im NOT that wild of a driver. (445whp)
