I would think that it is going to be hard to do this conversion mate, just because I dont think that there are really many ae86 in oz with one in, I think ive seen one in a magazine that had a 1jz. Obviously if you have the cash to cover it anything is possible.
Many ae86 drifters use the 4age in theres and from the pictures they dont seem to have much a problem why not just go for a 4agte if you really want a turbo, there are a couple around that are pull 200+rwkw.
