Certainly not saying duplicate everything you see on here. I enjoy reading this thread and you’re a smart guy for trying to search better content. I was just mentioning those builds for an example. with Chris Andrews advising you on what needs upgraded, you’ll be fine. Just wanted to share is all. The stuff you initially listed are the main components I would say are required for a high HP build. Being a non trans brake unit, you may get lucky with no 300m input shaft output shaft and billet hub, but with how much power your planning on having and giving it nitrous, I would certainly recommend them in your case.
I do like your 2.28 ratio choice.
