what is the best engine to put in a 92 celica gt?. (power)

i would also like to know if there is any major problems converting fwd to awd. like would i totally have to customize most of the parts and brackets i need or will some match up?

basicly i want an alltrac but i have a gt, and im willing to work hard to get it.

my current engine is a 2.2 ltr
