Well we all have options. I could always pull the motor again and sell the turbos to get something else. To answer your question, I'm pleased because the turbos have met my expectations and I feel I have yet to reach their full potential. Right now I'm runing high flow cats and stock manifolds. I think i can still improve my cars performance in those two areas. I think the Sport 530 are great turbos with a proven track record, but the price was a little more than I wanted to pay.
