GTS is a bigger engine as I said this is what it would take. However it still does not have much more torque down low and still makes its power up top. Gthal was talking about an extra 250-350 foot pounds. I understand it is possible to increase torque and keep a high revving engine but if you want 300 more foot pounds you would need to really increase the displacement of the engine (unless you use FI) and if you do want the torque available really low and in the middle than you need to tune the engine delivery for that and that would make it impossible to make peak power at such a high rpm.
