High torque motor isn't really required unless you're pushing a really heavy spring. If I'm not mistaken, you're keeping this gun under 350 fps so you can use it indoors. No need for high torque anything there. I'm sure that even wtih the stock spring, new hopup, tightbore, and a bearing spring guide, you could get the gun up to the 330-340 mark without having to replace anything else.
