The only parts you really need to get from Japan are the starter, alternator, water pump, and headgasket.

doesn't the Primera have the SR from factory?
anyways, the primera is FWD

Edit: the Primera P10 and P11 has the SR20

Just to note; I beleive it is possible to use a DOHC KA24 alternator if you swap pullies and modify the tensioner bolt hole.  Also, I have read you can use a SOHC KA24 starter if you swap the head from an SR20DET starter.  These are only really helpful if you have already have broken SR alternator or starter.

What about wireharness?
