First things first the Caliber srt is FWD. Now lets make a list of front engined cars that are AWD 1and2 gn eclipse, evo, wrx, 3000gt, audi quatro, skyline. Lets get rid of the engines and trannys that probally wouldnt fit and or have the trans pointing the wrong way. That leaves eclipse, evo, and, wrx. The wrx is a boxer which makes it a pain in the ass to do anything to it plus even wrecked wrx's are expensive. The evo has a bunch of electroinic mess to deal with and will be expensive if you can find one wrecked. The eclipses are old, mechanical, and cheap sounds like you have a winner. Now break out the vast array of saws the welder and a tube bender. You will probally have to make a rear subframe to hold the diff, axles and ect. Have fun and let us know how it turns out.
