On the average the stock flywheel cost about $500
$150 for the disk and $250 for the pressure plate.
Most performace shops charge about $300 for a clutch install. I rather pay someone to put mine in but it not too bad doing it yourself. Only if you dont mind working in about 24" of space under the car and have all the tools.
