A bit of a pointless poll unless you are going to be willing to upgrade the headlamps too. You do realise the Phase2 Mk3 have different shape headlights and grilles right? This is why the last Phase2 GSis had early headlamps - so the GSi grille would fit.
Thing to bear in mind is they're both modified. As standard I'd take the V grill, modified with mesh like that I'd take the phase 1 for the cleaner look.
The standard phase 1 grill (non-gsi) looks orrible.
Phil, I have a phase one filled out and meshed like yours and I have just ordered a bad boy bonnet lip - so I guess it will look like yours, one question though- what did you do about the bonnet release catch? Did you just remove it or extend the 'handle' so you can still get to it through the grill?? cheers mate, nice motor btw :beer:
