What 5-lug swap you use all depends on what wheels you want to get and what type of braking you want.
There are cheap $300 conversions which offer no brake upgrades and allow you to run limited wheels...to mild budget SN95 conversions which do upgrade brakes, to Cobra SN95 conversions which offer great braking to high dollar brake systems from Baer and Brembo.
Guys are putting together Sn95 conversions for cheap these days as parts from wrecked Sn95's flood the market. $500 is a reasonable budget to put one together (not including wheels)
