1992 eagle talon tsi awd I believe have an original 7 bolt but it needs a engine so wondering if 6 will fit stock transmission?

No, a 6-bolt engine will not fit directly into a 1992 Eagle Talon TSI AWD with its original 7-bolt transmission. The engine block's mounting points and the transmission's input shaft are different between the 6-bolt and 7-bolt engines. You'll need a 7-bolt engine or a significant amount of adaptation work (which is usually more costly than finding a 7-bolt).
