FAQ
Is the 177272 a T3 or T4 inlet?
It uses a T4 divided twin-scroll inlet (0.91 A/R).
What are the core wheel sizes?
60mm compressor inducer; turbine wheel approx. 76mm inducer / 68mm exducer. Journal-bearing center section.
Will this bolt to my factory setup?
Not without supporting parts. You’ll need a T4 manifold, compatible downpipe, correct oil feed/return (-4AN feed, -10AN/-12AN return recommended), and charge-pipe adapters.
Streetable as a single?
On mild fueling/timing, it offers good drivability for many 5.9/6.7 builds. For quick spool + top-end, consider S300/S400 compounds.
