Could sum1 please tel me if this is a uk box or import as I can't find this code on any chart this is in my 94 import wrx and is nackard also how would I find the rear diff ratio hope sum 1 can help me out. Thanks

 

Anything with VN is a uk box and is 3.545 rear and 3.9 front.

 

Thanks also bit more help how do I find out wot ratio is of the rear diff is there a plate with it stamped?? The box that shud b in the car shud b 4.111 but I'm not sure wot the previous owner has been up 2 I'm goin 2 go bk 2 ty752vb3aa that shud b in it but need 2 make sure rear diff is goin 2 match

 

the rear diff you have in is a 3.54 the diff for vb3aa is 4.11 you would need to change your current diff to match its original box.to identify your diff it can be done by removing the back plate and th eratio is stamped on the crown pinion wheel,either get a box to match your current diff or source new box and matching diff.

 

Thanks 4 the info
