Gaar

Hey guys, I got a 1990 lego, manual 2.2 and i'm in my final stages of making it a vehicle that can survive where I live. Lifted, Locked, Updated breaks, quality rubber, etc. I would like to be able to gear it down with either a older model transfer case or just fully change the first gear ratios..There is one other 93 Impreza in my town that has already done this, so I know its possible. Although he is out of town for the next few months. Anybody know what generation transfer case I should be looking for? I have access to an 89 Loyal T/C Taking ideas...This is also a budget car Thanks g
