Copied,
i can see this question being asked more than once. here is a list of the parts required to do the conversion, if i have missed anything let me know and i'll update the post (its 10:26pm and i have been at work since 4, thats 4 this morning which means i got up a 3 to get to work )


AE86 or AE71 engine crossmember
AE71 gearbox x member (86 one can be used)
AE71 pedal box
AE71 or AE86 clutch master cylinder
AE71 or AE86 solid clutch line from master to slave, and rubber hose
AE71 or AE86 rubber engine mounts
AE71 or AE86 steel engine brackets
AE71 or AE86 gearbox stays (link box to block)
AE71 tailshaft if keeping the ke70 borg diff
AE86 tailshaft if using S series
AE86 tailshaft with T18 back half if using T series diff
T50 gear box
obviously a 4AGE of some sorts JDM being easier, ADM FWD being a little trickier but no big deal.

thats just what you need to get the engine in there, you will also need

modify tank pickup with fuel pump, plus mod top tank plate with a 8mm fitting for fuel feed.
fuel hose (injection spec)

loom to suit, either modded AE82 loom if using a bigport, modded AE92 loom if using a smallport, or a slightly less modified JDM loom again if you are using a bigport.
