Guys: I have a dilemma.....I have a 1991 Legacy Turbo 4EAT TZ102ZJ1AA...just did a tranny swap.... the donor numbers are TZ102ZB3AA-N7
While driving the car there is a diff lock scenario where I feel alot of shudder and hear some growling noises in the center/tranny area. I put the fuse in for FWD and all the crap goes away.
The donor tranny is an Imported 2.0 turbo/tranny combo with all electronics and harnesses. The wiring from the tranny to the chassis was plug for plug...exact match. At this point only the tranny swap is in place. The engine will be installed in the next few months.
Here's what I would like to know.....What the heck is the tranny front and center ratio I have just put in front of my 3.900 viscuous rear diff? Again I have mated this with a 2.0 turbo tranny TZ102ZB3AA-N7. I have been told the engine is an EJ20T spec g with a black water cooled intercooler, igniters at each plug, and a 90 degree turbo, very likely from an Australian Legacy (Liberty)Turbo.
I need to decide how to proceed...first I need to know If my ratios are the same....does anyone have the ratio info for the donor tranny part# TZ102ZB3AA-N7
Next, I am wondering what the symptoms are of a fried rear diff. I became aware of the fact that this car had the FWD fuse "IN" blocking the AWD before I ever touched it. What does a viscous rear do when it ever fails?
I have lots of parts cars, own a Subaru repair shop and this one has me begging for your expertise. Please feel free to ask about parts availability, I will reward you for your kindness. By the way, I have two EJ22T strong running engines that I could make available to a worthy buyer! They are a radical difference from the non-turbo engines. Closed deck design!! I also have a ton of ea82 turbo and non-turbo parts engines and chassis-es(?)
