Funky gear ratio question
Posted 18 February 2005 - 05:32 PM
My wagon has an RX 3:7 dual range full time tranny in it. However, its been dropped to 4:11 to match up with the 4:11 LSD I have. So.....what ratio would that put the RX 1st gear into when in Low range? --E

You need 1st gear x low ratio x final drive
so you have 3.545 x 1.196 x 4.11 = 17.425 overall ratio.
Maybe... a thought for those who want a 4.11 final drive, perhaps the FULLTIME 4wd RX box, like this man has is the same setup as the later RS legacy trans(also fulltime 4wd but with the lsd centre). If so, you can use the pinion shaft and crownwheel out of the ej20 box and slot them into the ea82 box, since the pinion is on the end of a longer shaft with splines for the centre diff.

the diff sticker may not be true if your Mech.....was swapping things......What really needs to be done is a Spin test in the rear....to verify 3:70 or 4: 11 gear set.....
Or pull the rear and physically count teeth.....
I have been Researching this 4:11 gear swap into a Hi-Lo Box for Several yrs now.......I wish you were closer I'd Love to look at the work done to your Ride....
