We have a 67r kit-and full motor build going to a customer with a VR-4 up here. He is purchasing all the supporting parts, so I think he will make every bit of 680whp. We have made over 700whp with out 67mm T3 turbo kits on Evos, so its realistic.
But-I don’t think he will be coming down to Columbus with us, so you should be worry free.
