I was thinking of getting a supercharger to put on my KA .. But they're just too expensive! it's like over $2k for just a vortech or an eaton 62 .. I can get a whole turbo conversion kit from the US with a BALL BEARING turbo , intercooler, wastegate and all piping for $1500 landed. and really a turbo has just as much low down torque if you set them up properly.
