GA16DS to SR20DE

Hey all looking for help, i'm currently looking to swap my 1600cc Primera LX (GA16ds) engine for my 2000cc (SR20DE) out of my Primera GT, Wondering if it will fit straight in without modification and wondering wat wires i will need from the GT. Just wondering if someone could post up a check list or diagram (if possible) so far i have disconected all the hoses to the engine, taken out the wiring loom in the engine bay. Would i need to take the ignition barrel aswell ?

Thx Jason
