I think you should go for it. It's kind of like when people upgrade the stock fuel pump and then eventually go for a larger turbo/injectors, if nothing else you'll have if you decide to go bigger. P&P the stock turbo is a good move as well. I have a Monster P&P TD-04 and it's great a great daily driver turbo. It spools great and I don't have to deal with upgrading the fuel system, intercooler etc.
