just wondering for all of you drivers that are using a 091 6 rib tranny behind the subaru turbo motor. What do you do about the differiental.. do you upgrade it to the super differ? also do you change out the gears to better gears? i'll have mine as a street rod with street tires so im not sure if im suppose to change the differential and the gears out.. would like some inpute n help.

just use the standard gears..leave it as it is!!

i had a NA EJ20 in the stock 85 transporter with a 4 spd. Blew a gear right out of the box housing after about a year or so. however i dunno how the previous owner drove it before me. I would go back pull the box out and put better gears and a super diff in it. Also might turbo next time as i heard then can handle the extrapower with those mods. . . . SAVE MORE MONEY IN THE LONG RUN!

If you plan on putting big chunks of power through it,,, then maybe talk to someone in the know about some "Albins" gears & shafts & maybe a "peloquin" diff for it

i just did all that to mine & so far so good,,, but that`s after blowing a gearbox/diff nearly every month for the last year or so :-)

If you go down the tuff 091 road set aside 5~6k as a ball park
