My Setup: (just dropped in the CTR intake cam today)

17,250 miles into build on new block/refreshed head

10.85:1 static CR
99 GSR head
CTR intake cam, skunk2 gear on intake
GSR exhaust cam
GSR/ITR head gasket, ARP head studs
ITR valvesprings, LMAs, GSR retainers
01 ITR block, ITR flywheel spun: 13.5lbs
stock GSR header with 5mm lifted ports, stock cat, gsr s/b pipe
98 ITR muffler
GSR intake with 4" to 3" CAI tubing to box, sealed, stock hose to
TB, stock honda air filter
70/60/68 tapered GSR TB, portmatched to IM at 68mm
secondaries opened for more flow, butterflies knife-edged
fluidyne radiator/GSR thermostat runs at 35-40% all the time

tuning if any:
+3 out of 10 on intake cam degrees advance (+1.5 on gear)
lashed .0065/.0085
18 timing, NGK 6-plats/wires
fuel pressure reg w/o vaccum 52.5 static psi (until I can see
a fuel curve, dont want to run lean)
10-40 amsoil full synthetic

I estimate this setup is netting 165-168/123-125 to the wheels corrected with
about 120-123/120-123 at 5252, pretty healthy acceleration increase with the cam,
especially with the +3 advance.

previously it dynoed 158/121 with all above at 18 and 0,0 cams 1500 into its life on GSR cams.

If I added:
ported JDM DC 4-1 stainless header $250
2.5" carsound cat $125
2.5" APEXi WS exhaust $450 (reduce bottleneck at exhaust)
Titan Cam gears, retune $200 (reshape airflow through motor, easy to read
K/N filter for my box $50
97+ Prelude Injectors $300 (remove some bottleneck at fuel system)
V-AFC $325 (fuel tuning)
give or take $1800 with tuning unless I can get some hookups.

tuned properly what gains could I see? I estimate 175-180/130-135 corrected with good midrange power. any thoughts?
