just got the gearbox for my 4eat to 5spd conversion...

the donor is Subaru Impreza (wagon) 1997, ej20... the box is dual-range...

can anyone tell me the diff ratio on these boxes? I need to figure out what ratio the rear diff has to have as I'm not going to use the rear diff out of the donor car due to different inner hub type....

I think the box is 3.9 but I'm not 100% sure...

the gearbox code is: TY752XRCAA

hmm...

all assembled... have made a couple of testdrives and here is what seems to be wrong...:

when rewing the engine at speed (2nd, 3rd) the car starts to vibrate at higt rpms... driveshaft ballancing?

the transmission gets pretty hot... what is a normal operating temperture of a subaru manual trans? could that indicate the front and rear diff ratio is messed up?
