Introducing the MAP EF3, our attempt at the proverbial "best of both worlds" turbocharger. It's capable of making 100whp more than the EF2 (more than enough to add a window to your stock block should you so choose) while still retaining manageable spool characteristics for your daily driver or weekend warrior.

This turbo features upgraded thrust components with dual oiling ports for improved lubrication, upgraded monster thrust bearing material, a 2.4" comp cover inlet and a brand new, super efficient compressor blade profile that we are confident will outperform any wheel with the same inducer/exducer dimensions.
