don't listen to ANYONE, its not an easy conversion...... belive me im still going through with it.
engine will sit nicely in the bay, but FE cars had different A/C piping so your dipstic will be rubbing on the piping (nothing really major)
wiring is A REAL PAIN.
go aftermarket sraight away, but for most part you would like to have an ECU from Fe car...... there are some bits and peaces on FE that not a lot of aftermarket ECUs be able to handle. you can't use your F2 ECU as the signals are different, esp if you have later then 94 model FE (mine is 97 and its a PAIN)
on average you will pay 500-1500 for the engine
another 2000 or so to fit and tune AMM
also about 500-1000 on unexpected things (like i have to change fuel pump as ZE needs more flow then F2T

)
if yours is manual as is, you can keep it no problem, though your gearing will not be very well suted to the engine. you can go with BP gears to better sute the engine or better yet FS-ZE gears...... this will need some work, even though actuall gearbox looks like it will bolt up to F2/FE bellhousing...... matching final gear and diff that could be a problem (90% sure it will)
Turbo will cost you a bit, while the lazer cut flages readily avalible the piping will need to be done for the manifold, but the downpipe on FE looks like its the same as F2 so it might be an option of using stock turbo(or the family).
though there is a lot more involved then just bolting up a turbo

. FE is a good engine but not as fantastic as its made to be, just remember this
with Fe you will have 7200 valve float, there are HKS solid buckets avalible to replace HLAs but its a real pain to find them. also you will rarely find them by themselves as they are in a kit with titanium valvesprings and oversized valves.
anyway, good luck dude and post some pics of your mates sportage :tup:
