East Tennessee Region SCCA

Well, I'm looking to swap out my ailing 1.8L engine and tranny out of my 96 Impreza Brighton (bottom of the line) and replace it with either a 2.2L from a 95-01 Impreza L, a 2.5L from a 98-01 Impreza RS, or a 2.0L from a 02-04 WRX. However, after doing a few autocrosses, I'm not sure i want to change into some gung-ho Street Prepared class. Can anyone help me out with my options as far as engine swaps and class changes go?
Thanks, -matt

well, you will probably be in some crazy class.....if you have to change the crossmember to put the engine in, you are not even legal for SM...but do it man....Your car would be pretty sweet with a 2.0 swap.
