The 200SX and the Sentra shared the same 1.6L GA16DE motor. I have been told there are some minor differences relating to motors fitted to automatic versus manual transaxles, so if you are going to a junkyard try to find one that was fitted with the same type of shifter.

One caveat: Some 200SXs (and the 1998 Sentra SE 2.0) were fitted with a higher-displacement 2.0L motor. These too will fit in your Sentra, and it's a VERY common swap to do, but you would need the motor, trans, axles, mounting hardware, and ECU in order to make that work. I would stick with a straight like-for-like swap and you won't have any surprises.

Yes. as long as your sentra is a B14 sentra with GA16DE and SR20DE (FWD version).
