    My friend is currently building a turbo 330ci, and bought a kit from someone that ran it for a while and it was all fine, however, I’m needing advice, guidance and opinions on what is needed in order to safely run it, even at a fairly low boost pressure.

    Fuelling, air etc, even basic stuff. The car already has -
    bigger injectors on a billet fuel rail
    540i MAF
    Forward facing intake manifold
    Turbo and turbo manifold
    Downpipe and exhaust

    looking for what else will be needed, looking at a Walbro 255 or a DW300 Fuel pump too.

    any help would be appreciated! Thank you
