Default fuel/ignition support opinion KA-T

yah yah i change my mind more than some people do their underwear but this weeks flavor is mild ka power. not sure of power goals wanted, but say something that would probably start out at ~250 to the wheels and in the end probably shooting for as close to 300 as possible while maintaining a conservative a/f ratio. lag is irrelevant in this. so how does this sound:

-walbro pumpomatic
-unstable hybrids top feed rail
-50 lb/hr (525cc) top feeds
-sard or aeromotive fpr with cute mini gauge
-z32 mafs
-ngk sparks
-msd 6btm
-apex s-afc2
-profec b2 (irrelevant really, but displays boost since not listing boost gauge)
-egt gauge
-oil psi gauge
-intercooled t3/to4e, stock ass 100k KA. my tial is .45 bar, aka 6.5 psi, definately not upping boost til assured tune is good and paranoia is gone.

things to note: unstable hybrids rail and 50lb'ers come as a package for $430 and includes connectors to wire up (high impedance so no resistors needed right?). this is easier to setup than tomei/nismo/denso sidefeeds that would drop and connect in, simply because its a deal for the UH equipment and seems easier to run the aeromotive or sard fpr. the stock one could be used if going with just injectors, but i figure to have as many aspects of tunability adjustable to make the tuner's job easier by having more things to fine tune.

z32 maf, pump, s-afc2 are self explanatory

what alot of people dont run is the msd 6btm. reading the description off of jegs and msd site, btm seems best for this application, but i really dont have much clue when it comes to choosing and ignition system, but this seems right. alot of ka-t guys are running just hacked mafs or z32 mafs with retarded timing, but its sketchy at times, esp like with like temps and etc
other guys run jwt but i'd like to not run jwt if possible (unless someone learns to reburn them or starts rom tuning KA ecu's in the future)

discuss/opinionize

please also note, ecu is 97 now but if i find 95 ecu soon i will be obd 1 converting and putting my 95 manifold on with deleted egr and charcoal can and all that stupid crap that nobody likes. jwt only deals with ecu's up to 96, though converting is only a few wire switches.
