I am looking to give my 2014 Ford Focus SE (hatch) some performance upgrades to make it handle similar to an ST or RS. I understand that in most cases buying a used ST/RS would be the most cost effective solution, however I am unable to operate a manual transmission due to disability (not that I dont know how to drive a manual, I am physically incapable). I would like to be able to take my car to local track days & similar events, however the SE hatchback isn't exactly the epitome of performance. I am looking to potentially swap in either a Focus ST or Focus RS engine & turbo (I understand that as long as the engines are from a 2012-2014 donor car they should fit fine). I would also like to upgrade my brakes and exhaust to match. If anyone has any tips/warnings about doing this I would be very grateful. Thank you.
