You can buy the HKS GTSS kit that comes with everything you need.
If you buy the Garrett Turbos, how much would it cost to buy all the other stuff seperately like gaskets, hoses, etc, etc that comes included with the HKS kit??? Anyone know??
ie: How much cheaper is it to buy Garretts and the other stuff needed vs buying the complete HKS kit?
Ive seen the HKS GTSS complete kit for ~3K - 3.4K.
Ive seen -7's for ~ 2.5K for two.
