Going single turbo with the doc 6766 kit. Also decided to upgrade clutch while doing this as I'd only burn out the act 6 puck I have in now (565tq rating) quickly. I see there's has been problems with the spec twin disk not lasting which worries me about spending the money on the twin disk. Mfactory offers a twin disk that's pretty reasonable in price compared to others while being a known brand. However the spec 3+, I have seen reviews of handling the power of single turbo cars fine. Anyone have any input to help my purchase decision? I already have a Mfactory smfw however the twin disk utilizes its own so this wouldn't be used unless I chose the spec3+.
