Hello, So I am in pursuit of new found power with my car. My goal is for 600RWHP on a stock TT block. I haven't done anything internally to the engine, but by the time I am ready to put on these turbos I will have the following - 850cc Injectors - Tunable ECU - 3" Turbo back exhaust - 60mm Throttle Bodies - Dual Intake - MSP Manifolds - Z1 Sidemount ICs I am not looking to run a regular 600RWHP, but if I turn up high boost for short periods of time I would like to run 600RWHP So my options are between the GT28RS with the smaller 0.64AR turbine housing (Z1 offers the kit as the GT675RS) or the GT2871R, also with the 0.64AR turbine housing (Z1 offers the kit as the GT725R) The boosting characteristics are important. I understand that the GT2871R will hit full boost a small amount later than the GT28RS, but the GT2871R is like an on/off switch where theres no power, and then all of a sudden there's power a lot of power. The GT28RS from what I understand has a nice curve that contains desirable power in the lower RPMs. In fact, more power offered in the low RPMs than the GT2871R. What do you guys think? Thanks in advance for your inputs, Patrick
