Im a big fan of bang for buck setups and for between 3.5-4k i got
Tune
Turbo
Manifold
Gate
plenum
injectors
Z32
stack of 2.5",3" and 4" MS pipe
bosch 044
braided oil drain
Bunch of hose, nuts/bolts, joiners, heat shielding, clamps and gaskets
Pod filter
Ex cam gear
Ebay and the classifieds here were the weapons of choice!
I guess there's another 30-50kw left in it but would cost me at least another $1k for springs and some injectors to get there. Then you gotta take into account the extra component stress involved and i don't think its worth it.
with that said i don't think its fair to compare this setup with an IW garret or high flow low mount purely because of the legalities involved..
