If you are looking for any driveline performance parts, your best bet is an AWD gearbox converted to FWD. The high performance diffs won't fit in the FWD box. For brakes and the like, you will want to swap out the subframes from an awd car so you can run the rear disks and all of the suspension from the AWD cars.
as far as the engine goes, it will be the same as the 1.8awd cars.
