This is a stout power adder, for a very good spool up to 600hp! Brand new turbocharger! 61mm compressor wheel inducer, and the popular F1-62 exhaust wheel. T3/T4 combo, for a nice power curve, with a robust journal bearing. Comes with a T3 V-band out 0.85 a/r turbine housing, and a 1 year warrantee.
