the wiring was definitely a pain, I used my winter break to get the swap done the mechanical stuff was easy, a couple of days max, and then there was the wiring. I wish i had bought a complete wrecked legacy h6 it would have made the swap a little easier. the wiring would still have been a pain though I spent a lot of late nights/early mornings and it seemed like i would get no where. Mostly just staring at the wires.
For cost well the engine swap stuff with the interior swap probably around 6-7k
I know what the major components cost me
1500 for the engine
500 for the seats
700 or so for the interior
650 for uk ecu/etc
prob 700 or so for exhaust components
and then all the little stuff makes your money disappear faster than you think. Very much worth it though!!
