ya i forgot the + sign 
ya turbo vs displacement is a bit off!
the 362 is going to be way to big for road racing or autox but if you want to choose between the two i would def go with the 362. Personally i would go with a disco if your going to road race, at the max a 30r, those turbos are a blast on a 1.8 and you can still get into the 10’s with them in your hatch.
