I know ITR internals would help, but I don't know what parts I need. I want to spend nomore then $1500. Would swapping in all new parts be also considered as a rebuild? And ensuring the life of my motor aswell? I'm not looking to build a rocket, low 14 is more then satisfying for me, high 13's would be great. I doubt I will achieve high 13's. But please shed some light on this for me I'd really appreciate it.
