Hi guys I am new here, just have a couple of ?????

I am just about to finish building my engine it is a B20B block with a B16A head(DOHC VTEC 168hp) i did minor head mods(changed valve springs). I kept the block pretty much stock, same pistons and rods(for now). Changed the injectors to RC 310cc and installed a mugen ecu chip(before block swap). HKS intake, custom exhaust, ACT clutch.

Anyway my ?'s are
1) Does anyone know the recommended "break in" engine procedure?
2) the mugen chip was originally for the B16A engine, i was wondering if it would be still be okay for my "Frank" engine or if with the new injectors and all that the fuel maps will be all wrong?
3) We do not have a dyno in my country so i was wondering if anyone out there have these mods and could give me an estimated HP output.

Tried to keep it short sorry.
Thanks a lot
