Looking for the absolute best turbo money can buy? Look no further; the EFR series are the very best turbos ever made, bar none! Borg-Warner pulled all the stops in designing the very best setup that technology could offer, and boy did they deliver! No turbo has better response, and no turbo of similar size makes more power.

We strongly recommend the 1.05 A/R Twin scroll T4 turbine housing. This 62.6mm turbo is designed to make 475-750 HP
