So you want more power and dont want to deal with your crappy a604. I have the perfect solution for you! For sale i have a wrecked 1992 eagle talon tsi awd. Its got 155k miles on a 6 bolt 4g63 that runs awesome. The 4speed auto trans shifts perfect. The 4 bolt rearend is good. Its got everything you need to swap into your venge/sebring. I will let her go for 450. Car is located in central NY and you pick it up.
1st gens are totally different you would need a 2g to use the awd set up only thing you got there is a 6bolt with a ton of miles as for the auto you might as well swap to 5sp if your going though all the welding of puting in the 4g63
