Default need help with modifications yes iam a noob

firstly have a 96 1.8 mx5.standard engine.
just aquired a 99 head with all the bits like fuel rail and injectors but havent taken my old head off yet as i think i need the megasquirt to run it right?does that mean i can keep the fuel rail that comes with the 99 head is that a duel feed one?

if i want to get to 270 whp what do i need to do from here on in i was looking at the fm 2 without management and injectors but dont know enough about turbos to know if the turbo they supply is too small for my goal or if iam better off with a bigger turbo.or should i pick up parts seperately from various places?

from what ive read on here after 250whp you have to use stronger rods and after 300whp use stronger pistons.

so say i have the 1.8 the 99 head the megasquirt ecu can anyone fill in what else i need to achieve 270whp?
whats the best way to get my engine running with this 99 head? should i fit the megasquirt first and tune to standard engine then swap head then tune to the new 99 head then turbo it?

you can do a head swap without switching ECUs

you will not be able to control VICS

I haven't controlled VICS since I did a head swap, i intend to very soon.

You will need the FPR off your old fuel rail to convert the 99 fuel rail to a return system.

As for hitting 270hp you will need rods for the bottom end if you want to have a reliable motor that you can beat the **** out of.
