ive seen quite a few posts now about people bolting all the bits onto the N/A 4ages and them still handling a fair bit of abuse and being pretty reliable.
for those who have done it,
i was just wandring what other bits ya need etc and how hard it was to do, and how it goes, and how much boost you run could also be helpful
i have also seen a few posts about people with gtz's building up bluetop heads for them i assume for compression reasons maybe ?
but the gtz bottom end is what makes them more robust for boost reasons so bolting the bits onto a complete bluetop prob wouldnt be to healthy if you plan a pulley kit etc,
cheers
