i would definetely do it yourself if you can. it isnt hard at all. the hardest thing to do on vehicles now a days is diagnose wiring and electrical issues but to me none of its hard because ive been doing it for soo long and have done it for a living. now just on the side or my own car. It took me 2 hours to get the old motor out when i first bought my current se-r. i spend about an hour cleaning up the messy oily engine bay and getting everything inline ready for the jdm. the weekend came and prepped the jdm and put the tranny and everything on and and put it in and buttoned everything up. that only took another 3 hours or so with putting fluids in and double checking all the bolts and for leaks. done and out the door. i did have a cherry picker also
ive done motor pulls out the bottom and out the top and personally i think out the top is better. but its still easy to do out the bottom if you dont have a cherry picker. its just a pain sometimes to get the front of the car up high enough to pull the motor out from under.
the turbo setup didnt take me but a day and a half, that was including, the fuel pump install (1 hour) s4 cams install (2 hours and that was because my chain skipped a tooth on the crank so i had to advance both cams 1 tooth) drill and tap the block 2 hours includes allowing silicone to dry. turbo oil line 30 minutes, safcII install 2 hours, injectors 30 minutes, turbo manifold, turbo, downpipe all in at once. 1 hour. fmic and piping install 3 hours or so. 300zx maf install 30min. Fidanza flywheel and ACT clutch kit 2 hours.
its a lot to do none the less. just take your time with it. i started on it saturday morning ad i was done with it mid sunday working on it for 8 hours or so on saturday and 4 on sunday. it was done.
