Hi Ipin, few things to take note:
Stock TD04 turbo outlet face upwards, U will need to do some custom piping to join a FMIC, which mostly has the inlet & outlet at the sides & located lower.
There are 2 version of TD05 turbos available, EVO 123 & EVO 456789. Not sure about the older ones, but the newer version TD05 are twin scroll (2 entry type), will not bold-on to your stock exhaust manifold.
It's a personal preference, changing to FMIC alone will help prevent detonation & maintain the boost responsiveness.
Changing to a more efficient turbo will be even better, but there'll be a increase in lag, expect boost to delay 500-1000rpm depending on which TD05 U choose & overall setup.
