Default B20 IM/TB header question for all you NA guys

this is my setup.

B20B Block
Balanced 89mm crank
Eagle Rods
84 mm 12.5:1 CP pistons
ARP hardware
Mugen Oil Pan
Head:
B16B Head
Skunk 2 Stage 2 Cams
Skunk 2 Retainers & Valvesprings
AEM Tru Time Cam Gears
Rocket modified spark plugs
Fidanza 7.5lb flywheel
ACT Extreme Pressure Plate
ACT Street Strip Disc
CTR N1 crank pulley
AEM alternator pulley
AEBS IM
AEBS 68mm TB

after reading the thread by king motorsports on the 93 octane b20
im not so sure if i should use my aebs IM and TB since i have a p73 IM and TB layin around. and i think i may go with a hytech reproduction header, im just not sure yet. or do you think my jdm type r header would work.
let me know. thanks

bigger header is gonna be alot better for a 2.0 especially with that compression. as far as the intake setup, id just leave it rather than go to a different setup. what kind of fuel system are you going to use? sounds like a decent setup though.

well this engine was nick m`s old engine from his hatch..

as far as fuel system i have type r injectors and a str fuel rail with an adjustable fpr. i was told that the type r injectors should have plenty of pulse with however i do plan on upgrading to a 255 fuel pump and probably 310cc injectors before i take it to get it tuned. do you think it will be ok to drive it around untuned for a little while?
should i run my p72 ecu or my p30 till i get it chipped and dyno tuned?

i think im going to just put the type r injectors in and run it with the stock fuel pump and retard the timing -2

and as far as keeping the same setup as jeffy said.. i have both, the aebs im and aebs 68mm tb and i also have a p73 im and tb..
just not sure wich one to use..

please bear with me guys i just recently got back into the honda game and i have a lot i need to learn.. i just dont want to break **** in the process..
so any feedback/help or suggestions would be greatly appreciated

what kind of management are you going to be using? i would recommend getting that with a base map on it already for the new pump and injectors. set the timing at stock settings as long as the map seems to run it fine, and only drive it to the dyno for tuning, and drive it easy on that ride. run the blox setup for sure. id port/clean it up on the inside before installing it though. good luck.
