Tranny gear ratio Questions, please help im new to the svx world

[noitseuq]

Hey guys i just recently bought a laguna blue 1994 svx FWD immaculate condition and 75k miles.

My plans with the car is to convert it to a AWD 5 speed manual

What i have bought for the swap already is and COMPLETE drivetrain from driveshaft to hub / and sub frames off of an AWD 1994 SVX.

The tanny i think im going to go with is the 02-05 wrx tranny.

now the only thing im stummped on is that if i use the o2-05 wrx tranny it says i can leave the rear end stock?! the reason why im stummped is because isny the final rear of the svx like 3.45 or close to that? and isnt the wrx 4.xx?

someone please clear up my ignorance on this car and refering to what i have car and parts combined, what tranny do i need?

thanks much
