Popular Build Paths
Single T6 Upgrade: Requires a T6 manifold and matching downpipe. Expect later spool than T4; major payoff in top-end flow.
S300/S400 Compounds: Run 177287 as the low-pressure (atmospheric) unit with an S300 high-pressure turbo for fast spool and huge airflow.

FAQ
Will the 177287 bolt to my factory manifold?
No. The 177287 uses a T6 twin-scroll inlet. Most light-duty trucks are T3/T4. You’ll need a T6 manifold plus compatible downpipe and piping.
Streetable as a single?
It’s designed for high horsepower. On small displacement/stock fueling, spool is later than S300/T4 S400 options. It excels as a single on built engines or as the atmospheric charger in compounds.
What are the inlet/outlet sizes?
Typical S400 sizing: 5.0" compressor inlet, 4.21" V-band compressor outlet, 5.75" Marmon turbine outlet. Check your exact housings before ordering.
Oil feed & drain?
Clean, unrestricted feed with a -10AN to -12AN return line is standard practice on journal-bearing S400s. Avoid restrictors unless oil pressure is excessive.
