No. Definitely not. RPW's setup uses a turbo manifold whereas RRM's uses the stock extractors and a return pipe.
If you plan on upping the boost from 5-6 psi at ALL I'd really recommend the T28. And don't skimp. Be sure to get an LSD or you'll be spinning and smoking tires in first and second without even trying.
EDIT: Oh yeah, and supposedly RRM will be making a turbo manifold eventually, but I originally heard that in September. They're already way backed up on development and Rob is having surgery done so God only knows if/when it'll be done. Either way you can't go wrong. In my opinion both kits have their shortcomings but neither is bad.
