Buildup of B18C1 vs. frakenstein engine

I've got a 2000 Integra GS-R (B18C1) basically stock, and I'm looking to buy another engine/tranny/ignition/ECU and build it up.

Goals:
250hp @ wheels, all motor
higher redline (9000-10000 rpm)
looks/sounds as close to stock as possible
still tolerable and reliable enough for daily driving
safe to put a 15psi turbo or supercharger on later

I've seen a lot of banter back and forth about putting B18C heads atop the B20 block, using a B17 crankshaft, etc. I'm trying to gather as much as possible about the ideal crank/block/head combination, with no price limits. I'm expecting this project to end up at about $10,000 US.

Thus far, the general idea is to make the following upgrades:

Bottom End:
clutch (clutchmaster)
flywheel (ITR or clutchmaster)
connecting rods (ITR or crower)
pistons (98 ITR - 10.6:1)

Tranny:
limited slip differential (undecided - any advice?)
JDM Type-R final drive (4.78:1)
Perhaps a less aggressive 1st gear
want to look at stronger CV's - I snapped 5! in my old 4g civic

Head:
camshafts (skunk2)
adj. cam gears (aem)
valves/springs/retainers/sleeves (JUN and skunk2)
milled head
mugen metal head gasket
port-matched exhaust to Spec-R
pulleys (unorthodox)
alternator pulley (if unorthodox doesn't come w/ one)

Electrical:
ignition (crane)
ECU Mod (G-Force custom-programmed) w/ 9500rpm redline, better A/F mixture mapping

Intake/Exhaust:
AEM cold air (long-throw)
intake manifold - not sure yet
individual breather cap for crank case
ITR 4-1 headers
ITR cat. converter
skunk2 Invidia cat-back

suspension/brakes/wheels:
any given 17x8 wheels
yokohama AVS tires to match
koni adj. shocks
eibach pro-kit springs
slotted rotors in front
old front rotors moved to rear

I'm wondering if there's a better block/head combo than the B18C1 to start with here. Since I'm looking to buy a completely separate engine, I'm open to anything. Is there anything hideous and awful I'm including or missing?

I don't know which Frankenstien swap you are refering to, there are many of them. If you mean a type R head on your B18C1, that is a possibility of course, although probably not a dramatically beneficial one. However, I do know that any swapping of heads might make your car a little unbalanced, even unreliable. But done correctly, you shouldnt have that many problems. If you are talking about 15 psi of boost however, I would reccomend getting low compression pistons and more fuel delivery. For 15 psi of boost, I would stay with the B18C1 for reliabilty purposes.

Oh yea if you want to rev 10k, you can increase the gear ratio of your final drive gears. This will make you rev higher and reach your redline faster, but you will top out at a lower speed. It's a trade of acceleration and revs for top speed. However, this shouldnt matter too much if you are just going to be racing 1/4 miles.

I think he is talking about the B20. The only Frankenstein.
