The EFR 6258 is the smallest turbocharger in the ultra-efficient EFR lineup. The 62mm OD compressor has a 49.6mm inducer at 44lb/min max flow - supporting up to 440hp with very large map width for outstanding power potential even at high boost. The 6258 is the fastest spooling EFR turbo - and fits in a small package.
Ideal for small engines in single turbo configuration and stock internal or modified engines. This is an excellent turbocharger for autocross, rally, drift, road racing and street driven applications. The low inertia 58mm Gamma-Ti turbine wheel is optimally matched for maximum response and fastest spool with the FMW compressor wheel.
Standard is .64 a/r with T25 Inlet.
.92 a/r with T4 Inlet is optional
