Building a motor is based on the goals you’re looking for and those goals will drive the rest of your choices for the drive train. This isn’t meant as criticism, but you need to talk to someone who can explain the whole package to you. My suggestion is to get a good Machine Shop in your area, which hopefully some members can provide you. Tell them what you’re looking for and your budget. They will put together a motor with all the correct pieces for you, which is better than you trying to piece things together for yourself given your knowledge about performance applications. You can end up spending a whole bunch of money by listening to all the comments you get in this thread and you still may not get what you want. Just my two cents worth.
