i just finished my 1j swap and it wasn't hard at all once the harness is converted. i bought a engine, harness, ecu, ignitor, and map sensor from driftmotion for $2100 but i already had the trans. after that there's a lot of little things you need like the high press. power steering line either custom or driftmotion or 2j( i think), also you need to figure out weather your gonna use the hydro fan setup or if you want a e-fan or mechanical if you go with the e-fan/mechanical you will need a 2j water pump and pulley. also you will want to replace all the vacuum lines and all the water and oil lines to prevent any leaks later. i no there's a lot more but thats the basics of it. im not sure what your planning for a budget for your swap but i would suggest around $6000 i only say this cuz i only allotted $4000 and i had to wait in the middle of my swap to save up some money to buy the remaining parts.
