Bin the front mount. You will need the to open your engine and do a heap of other supporting mods to install a turbo big enough that needs a front mount. A good combo on a stock rex is a VF34 turbo matched with either an sti or process west tmic. Fuck all lag but plenty of punch all the way to redline. But really it depends on how much power you want, which you have not said.
