you can fit the head and the manifolds (would then need a gti6 cat/de-cat) to make a bit more power on the xsi, not sure what power you would get from it as the compression ratio would be a little different due to the pistons being different to the gti6 (they have a pocket in the centre)...
I think they run a different crank too... Obviously it'd be best to get an unlocked gti6 ecu and fit gti6 injectors and make sure you have the relevant MAP sensor and the camshaft sensor is there and wired up.
