search for more info, there's a couple threads pertaining to this swap. anyhow, you have the donor car, might as well swap everything out. you still have to swap out the passenger side motor mount, use the sr20 engine harness but modify the ga16de accessory harness (starter plug). through my experience (98ga16 to 98 sr20), both throttle and clutch cables were different in size, but like i said, might as well swap everything out. might wanna consider swapping out the power steering rack, it is different.
