Some people recommend me to use a turbonetics t60-1 ball bearing for a daily driver of 18psi, but some other recommend me to use a t66 ball bearing… I know that a smaller turbo will be better in a short run, but a bigger turbo will be better some other application… the thing is that I think that by putting a smaller turbo comparing to a t66 o t67 ball bearing, it will be a better reaction but the question is …… what turbo will be better for a long run?
