G series ratios.

[strat]

Hi all.

Just need help finding a ratio for my improved production KSEVS.
It runs a hilux g series diff and I'm looking for something around 3.9 to run at Phillip Island.

A mate has a 04/1991 4runner it's a petrol v6 auto 4wd. Model number is vzn130r - gkpseq engine is a 3vz-e.
Would that have something close to a 3.9?
I would rather find out before pulling it appart and counting teeth.

Any help would be awesome.

i put brand new 3.9 gears in mine, theres a few ebay stores that sell them, do a search, or i got mine from the states with a true trac centre for much cheaper than you can get them here.
