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?

 

Browse through the build threads. It's easier on everyone. Good luck with your mods.

 

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.
