Do you think the stock bottom end and stock internals are good with the F-1R with the rare occassional high RPM's?
My objective is to have higher boost at lower RPM's to obtain more low end TQ numbers. While taking into consideration my future goals, I'm thinking better to go with the F1-R up front than the D-1SC and then have to upgrade later to the higher model.
What's your honest opinion?
