i currently have a 2000 gsR that is pretty much stock. i purchased a usdm type R head(rebuilt) and intake manifold, and a block that will need to be rebuilt. it has been previously sleeved and one sleeve cracked due to un-tuned boost driving by the previous owner. so my plan is to just throw the engine on a mount and rebuild it. i'll send the block to a machine shop and get that fixed up.

other than this what kind of other things will i need to be thinking about?
-wiring harness
-engine management
-ecu
-exhaust manifold
-???????
-engine mounts

what else? and do i need any of the stuff listed? or will most of my gsr stuff swap over?
