My setup runs a single 44mm wastegate with a suboptimal approach angle. It has zero trouble keeping this turbo under control.
Thanks! Yeah - it is mostly a potential for growth issue. If the cost difference between a 44mm and a 60mm is minor... well why not go larger, now - right? I really want to achieve symmetrical charge pipes and mount the turbo front and center (I'll kill the core support and run a more compact rad to achieve this). But, having the turbo offset, like yours, may be another option due to simplicity of packaging.
